Overview

AI-generated overview

Vinktar gives an assistant read and build access to product analytics and error tracking, so it can query events, errors and boards and set up SDK tracking.

What you can do
  • Explore projects, schema and raw events, and run trends, funnel, retention and read-only SQL queries
  • Review error issues, their occurrences, stack traces and fix checks, and update status or assignee
  • Create, read, update and delete boards and panels, and manage alerts and their recipients
  • Define tracking-plan events and write project notes for agents
  • Install guidance and setup checks: install guide, project keys, setup status, start and claim a project
When to use it
Useful when a coding agent should answer questions about traffic, conversions, retention or errors in a Vinktar workspace, or wire Vinktar tracking into a repository and verify that data arrives.
Requirements
Remote Streamable HTTP endpoint at mcp.vinktar.com; no key to paste. Sign-in happens in the browser, where you choose the workspace, projects and permissions. Some tools work before sign-in via a claim link.
Before you install
The connection can write: it creates and deletes boards and panels, creates and updates alerts, changes issue status and assignee, and defines events. Deleted boards and panels are restorable for 30 days. It returns a project write key and a claim link that only the owner should open; the source-map upload key is never returned. Data requests count against a monthly allowance, and every call is logged on the project's AI agents page.

Installation

In SourceWeft

  1. Open Vinktar in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.vinktar%2Fmcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

README

Vinktar for coding agents

Vinktar is error tracking your coding agent can read, with what the user did right before each error. This plugin gives Claude Code, Cursor and Codex three things:

  • The Vinktar MCP server (https://mcp.vinktar.com/mcp). You sign in in the browser and choose a workspace, the projects it may reach, and read, build or configure. No key to paste.
  • The setup skill. Run /vinktar:setup in Claude Code, or ask your agent to "set up Vinktar". It reads your repo, installs the SDK for your stack in a standard layout, fetches the project's write key over the connection, wires identify, errors and source maps, defines each event it tracks, checks what actually arrived, and ends with a list of every environment variable and where it goes.
  • The /vinktar command. Type /vinktar to set Vinktar up in this repo, or once it is set up to hear what broke. /vinktar what broke after the last deploy? asks a question directly.

Once it's installed, ask it things like "what changed this week?" or "which errors hit the most people since the last release?".

You don't need an account beforehand. Before anyone signs in, the agent can start a project on its own (start_project), set the app up with its key and check that data arrives; you then open the claim link it gives you, which signs you in or makes your account and keeps the project with its data. Unclaimed, a project takes up to 10,000 events and is deleted with its data after 7 days.

Install

Claude Code

sh
claude plugin marketplace add vinktarhq/agentclaude plugin install vinktar@vinktar

Run /vinktar:setup. It can set the app up before you sign in; to ask questions about your data later, run /mcp, pick vinktar and authenticate.

Claude (claude.ai, the desktop app, Cowork)

Adding the plugin does not connect Vinktar. After you add it:

  1. Open the plugin's Connectors tab, or claude.ai/customize/connectors, and choose Connect next to Vinktar.
  2. Sign in or make a free account in the browser, leave Build and Configure on, and approve.
  3. Start a new chat. A chat that was already open does not pick up the connection.

Then ask "what broke today?", or type /vinktar.

Cursor

Import this repository under Customize → Plugins → From GitHub Repository. Cursor asks you to sign in the first time it connects.

Codex

sh
codex plugin marketplace add vinktarhq/agentcodex plugin add vinktar@vinktarcodex mcp add vinktar --url https://mcp.vinktar.com/mcp

The last line adds the connection and opens the sign-in in your browser.

Any other MCP client

Add https://mcp.vinktar.com/mcp as a Streamable HTTP server; it finds the sign-in on its own. Then ask your agent to call get_install_guide. Setup for each client: vinktar.com/docs/mcp.

A harness that reads skills but has no plugin format

Copy .agents/skills/setup/ into your repository (or your home directory, wherever your tool looks). It is the same skill, at the path most tools agree on, and it needs the MCP server added separately.

What it can and can't do

The agent sees what you'd see in the workspace and project you approved. The only things it can delete are boards and panels, and those stay restorable from the boards page for 30 days. It can't delete events, errors, issues or projects, create projects or keys once you are signed in, manage members or billing, or add somewhere new to send your data. Before sign-in it can start one project nobody owns until you claim it. Every call is logged on the project's AI agents page, and an admin can switch agents off.

Vinktar works on every plan, Free included. Data requests count against a monthly allowance; setting a project up never does, and nothing is charged per call.

Tools

add_panel

Add panel

Add a panel to a board. Each panel answers one question and reads at a glance: a number, a line or a bar. Build it from the structured types; `sql` is the last resort. Choose in this order: `funnel` for conversion through ordered events (viewed pricing → started checkout → paid), with a breakdown for conversion per segment (per shop, per plan): always a funnel, never a query or trend lines per step. `retention` for whether people come back. `trends` for everything that counts or sums events: `chart` "scalar" for one number (revenue, installs, failed charges; several numbers are several scalar panels, never one wide table), "line" for a metric over time, "bar" to compare segments over time, "hbar" to rank them, "share" for parts of a whole, "heatmap" for when in the week; set `display.format` to "currency" for money and "percent" for a rate. A series can carry its own `breakdown`, so one panel shows signups by plan beside checkouts by country; reach for that before SQL. A table only when the rows themselves are the point (the operations or shops to look at), with at most four columns. `issues` for the top errors, `text` for a heading over a row of panels: a single "## Heading" line renders as a slim section title. `sql` only when none of those can show it (a ratio between two measures), with at most four columns, the board's range as `{from}`/`{to}` rather than now(), and `sqlReason` saying why. A funnel and retention count the project's identified users: if the people in the question are not them, say so in a text panel instead. The spec is exactly what query_trends, query_funnel, query_retention or run_sql just ran (same field names), so check the numbers with that tool first. The panel is run once before it is saved: one that fails or breaks these rules is refused and nothing is saved, so follow the message and call again. The board is a grid: a panel joins the last row when it is the same kind and there is room (numbers up to four to a row, charts two, a table or

Parametersnamerequiredtexttyperequiredviewchartqueryfunnelissuestrendsdisplayprojectsretention+2 more

browse_events

Browse events

Raw events, newest first, under simple filters: event names, one user (distinctId), page search, property filters or a VinktarQL WHERE expression. Use it to see what one user did, or to inspect real payloads. Pass `eventId` instead to get that one event in full, every column and the whole payload. Windows longer than 30 days are narrowed to their last 30. For counts, use query_trends or run_sql instead of paging.

check_fix

Check fix

After a fix for an issue ships, start a server-side check of whether it comes back: occurrences on the fix release (or the next release seen) and later, against how many sessions reached that release, over a horizon of up to 14 days. It keeps running after this session. Read the result later with get_alert and the issueId. The result is never "fixed": it is recurred, no recurrence in N sessions, or not enough evidence.

ParametersissueIdrequiredreleaseenvironmenthorizonDaysminExposure

create_alert

Create alert

Create an alert: a query (source events, errors or sql; measure count or unique_users; filters; an optional groupBy; a window in minutes), a condition (above or below a threshold, or changed by a percent against the window before, a week earlier or the trailing week) and who hears it (recipients among members, saved channels, the team by default). Each series is judged on its own and a series that fired stays quiet for one window. Examples: new issues = source errors, lifecycle first_seen, condition above, threshold 0. Users affected = source errors, measure unique_users, windowMinutes 60, above 100. Signups dropped = source events, event signup, condition changed, changeDirection down, changePercent 50, compare week. Orders stopped = source events, event order_placed, below 1. You cannot name a webhook, a URL or an outside address: a person adds those in Vinktar. Only create an alert when the user asked for one.

create_board

Create board

Create an empty board in the workspace, to leave the user a view of what you found; fill it with add_panel, where each panel says which projects it reads. First decide what kind of board the request is, from the decision the user wants to make with it: "launch" when one feature or release just shipped: is it used, by whom, does it convert, did it break anything; "conversion" when a funnel someone cares about: where people drop and which segment converts; "growth" when the business at a glance: new people, active people, conversions and money over time; "engagement" when how much and how often people use the product, and whether they come back; "revenue" when money: how much, from whom, and the path to paying; "acquisition" when where people come from and which channels bring the ones who sign up; "reliability" when what is breaking and whether it hurts the flows that matter; "custom" when none of the above: a board shaped around one specific question. The result is a plan for that kind, filled in with the project's own signup, activation, conversion and revenue events: follow it, dropping what the user did not ask about. If the request fits none, ask the user what the board is for before building. Pass `expiresInDays` for a board built for one launch, so it deletes itself afterwards instead of staying forever. Only do this when the user asked for a board or agreed to one.

ParameterskindrequirednamerequiredprojectprojectsdescriptionexpiresInDays

define_event

Define event

Define an event in the project's tracking plan: what it means, its role, the properties it carries (type, unit, whether every send must include it, an example) and where the code sends it. Call it in the same step as adding or changing a track() call, before any data arrives; and for existing events once you have read the code that sends them. It takes effect at once, labelled as written by an agent, and the team can correct it in Vinktar. get_setup_status then reports defined events that never arrive and sends missing a required property. Conventions (get_install_guide with section "conventions" has them all): new event names and property keys are snake_case, object then past-tense action (signed_up, report_exported); a description is one sentence of at most 100 characters and a longer one is refused; an event already shipping under another spelling is defined as it is sent, never renamed unasked. Do not overwrite a description the team wrote unless the user asks. Setup call: never counted.

Parametersroleeventrequiredprojectpropertiesdescriptioncode_location

delete_board

Delete board

Delete a board with its panels. Only when the user asked for it, or agreed when you proposed it; name the board before you do. A person can restore it in Vinktar from the boards page for 30 days.

ParametersdashboardIdrequired

delete_panel

Delete panel

Remove a panel from its board. Only when the user asked for it, or agreed when you proposed it; say which panel before you do. The panel id is in get_board. A person can restore it in Vinktar from the boards page for 30 days.

ParameterspanelIdrequired

get_alert

Get alert

Read alerts and what they said. Pass alertId for one alert: its query and condition, whether it is on or snoozed, what its last check read per series, who hears it and what it said recently. issueId gives that issue's latest fix check (awaiting_release, watching, recurred, no_recurrence, not_enough_evidence or stopped, with exposure and recurrences on the fix release). Neither lists every alert in the project, what fired in the last 24 hours, and the saved channels an alert can post to.

ParametersalertIdissueIdproject

get_board

Get board

Read a board: every panel computed over a window with the change against the previous period, as headline numbers. The quickest way to answer "how are we doing" in the terms the team already tracks. Each panel shows its id, for update_panel and delete_panel.

ParameterstofromlastdashboardIdrequired

get_install_guide

Get install guide

The step-by-step guide for setting Vinktar up in the app you are working in: which SDK fits the stack (with current versions), the recommended file layout and environment variables, defining the tracking plan as you add events, proving it with get_setup_status, and the handover telling the person where each variable goes. Call this first when asked to install, set up or audit Vinktar, and follow it. It ends with Vinktar's conventions (event and property naming, descriptions, how an event changes, releases and environments, identifying users and connecting the browser visit to the server); pass section "conventions" for those alone before adding or changing a track() call in an app that is already set up. It answers before sign-in too, and then starts with where the person signs in from each app. Setup call: never counted.

Parameterssection

get_issue

Get issue

Everything needed to debug one error issue: what it is, its status and history, how often and for whom it happens in the window (by release, environment, browser, URL, tag), the latest occurrence's stack trace (source-mapped when available, each in-app frame linking to its file in the repository once the project's repository URL is set), breadcrumbs and request, and the product events that user sent in the 30 minutes before it.

ParameterstofromlastissueIdrequired

get_project_keys

Get project keys

The keys installing Vinktar needs: the project's public write key (VINKTAR_KEY) with the ingest host, the Sentry-compatible DSN and the Bugsnag-compatible endpoints, and whether a source-map upload key (VINKTAR_CLI_KEY, a secret) exists, with where a person creates one. The secret is never returned: tell the person to add it as a CI secret. Needs a read and write connection. Setup call: never counted.

Parametersproject

get_schema

Get schema

What a project tracks (or several, with `projects`, each under its own heading): event names with their volume over the last 30 days, the payload properties each event carries, user trait keys, and the columns and functions VinktarQL (run_sql) accepts. Call before any query so names are real. Pass `event` to see every property of one event, or `propertyKey` to see that property's most common values, which is how you find the exact spelling of one before filtering on it.

ParameterseventlimitsearchprojectprojectspropertyKeypropertyScope

get_setup_status

Get setup status

Check a project's Vinktar install from the data that actually arrived: events and errors received, users identified, releases and environments tagged, source maps for the latest release, items the SDK dropped, and key events described. Each gap comes with the next step. Call it after installing, and again after each fix, until nothing is left to do. Setup call: never counted against the agent allowance.

Parametersproject

list_boards

List boards

The boards whose panels read from a project, or from any of several with `projects`. A board shows what the team already decided matters; read one with get_board.

Parametersprojectprojects

list_issue_occurrences

List issue occurrences

Recent individual occurrences of one issue, newest first: when, which user and session, release, environment, page, browser and OS. Use it to spot a pattern (one browser, one release, one customer) or to pick a user or session to follow in browse_events.

ParameterslimitcursorissueIdrequired

list_issues

List issues

Error-tracking issues (errors grouped by fingerprint) for a project, or across several with `projects`, with occurrences and affected users inside the window. Default: open issues (unresolved + regressed) sorted by occurrences over the last 14 days. Follow up with get_issue for the stack trace.

Parameterstofromlastsortlevellimitcursorsearchstatusprojectreleaseprojects+1 more

list_projects

List projects

List the Vinktar projects this connection can read (a project is one app or site sending events and errors), with the workspace plan and what this connection is allowed to do. Call this first when you do not know the project handle.

Takes no parameters.

query_funnel

Query funnel

Conversion through an ordered sequence of events (e.g. view_pricing → start_checkout → purchase): how many entered, how many reached each step, where they dropped, how long converting took, optionally by segment.

ParameterstofromlastorderstepsrequiredfiltersprojectprojectsbreakdownconversionWindow

query_retention

Query retention

Cohort retention: users who did targetEvent in a period form a cohort, and the table shows what share of each cohort did returningEvent in each later period. Use it for "do people come back" and "did retention improve after the change".

ParameterstofromlastperiodfiltersperiodsprojectprojectstargetEventrequiredreturningEventrequired

run_sql

Run sql

Run a read-only VinktarQL SELECT over the project's `events` table, for anything query_trends, query_funnel and query_retention cannot express; start with those, since what they run is what a board panel should be. A ClickHouse-flavoured subset: WHERE, GROUP BY, HAVING, ORDER BY, LIMIT, DISTINCT, IN, LIKE and allowlisted functions (count, uniq, sum, avg, quantile, countIf, toStartOfDay…); no joins, subqueries, CTEs or INTERVAL, so filter time as `timestamp > now() - 86400 * 7`. Payload properties are `properties.<key>`, user traits `user.<key>`. Tenant scoping and plan retention are applied automatically. Call get_schema first for columns, functions and property names, and aggregate in SQL rather than paging through raw rows.

Parameterslimitqueryrequiredcursorprojectprojects

set_project_notes

Set project notes

Write the project's notes for AI agents: what the product does and for whom, the flows that matter (signup, activation, the paid action), what counts as an active user, and anything that makes the data easy to misread. Write them from the codebase during setup, in plain sentences, up to 2,000 characters; they replace the current notes, so read them in get_schema first and keep what the team wrote. Every later agent reads them before the data. Setup call: never counted.

Parametersnotesrequiredproject

update_alert

Update alert

Change an alert from get_alert: any part of its query, condition, timing, recipients (workspace members) and channels (saved ids or "#name" in the connected Slack). Or hold its news with snoozeMinutes (0 ends a snooze; a week at most). Switching an alert off or deleting it is a person's, in Vinktar. Only change an alert when the user asked.

ParameterssqlnameeventfloorlinkssourcealertIdrequiredcomparegroupByissueIdmeasurerelease+16 more

update_board

Update board

Rename a board, rewrite the line under its title, change when it deletes itself, or lay its panels out. A board is a grid: every row spans the full width, its panels share it (one to four) at one height, equally unless you give widths. Pass `rows` to set the layout outright, top to bottom, as rows of panel ids from get_board; panels you leave out keep their order after them. Or pass `arrange` to straighten the rows as they read now. Pass only what changes. Panels are changed with update_panel and delete_panel.

ParametersnamerowsarrangedashboardIdrequireddescriptionexpiresInDays

update_issue

Update issue

Change an error issue's status or assignee: resolve it (optionally in the release that ships the fix, or in the next release when it has not shipped yet, so a later occurrence reopens it as a regression), ignore it, reopen it, or assign it to a teammate. Only act on an issue when the user asked you to.

ParametersstatusissueIdrequiredassigneeenvironmentresolvedInReleaseresolvedInNextRelease

update_panel

Update panel

Change a panel on a board: its title, how it draws, its number format or what it shows. Pass only what changes; the rest stays as it is. The panel id is in get_board. To turn it into another type, pass `type` with the full spec for it, the same fields as add_panel. A changed panel is run and held to the same rules as add_panel before it is saved (structured types before SQL, one question per panel, the board's time range), and one that breaks them is refused with nothing changed.

ParametersnametexttypeviewchartqueryfunnelissuestrendsdisplaypanelIdrequiredprojects+2 more

whats_changed

What changed

Start here. One project's window, or several pooled with `projects` (every row then names its project), compared with the one before it, across analytics and errors: traffic (events, active users, sessions), the events that rose, fell, appeared or stopped, error volume, new, regressed and fastest-growing issues, and the releases that shipped, and what the project's alerts said. Each row names the tool to go deeper.

Parameterslastprojectprojects

start_project

Start a project without an account

Before the person has signed in to Vinktar: start a project for their app now, so setup can run and data can arrive before anyone makes an account. Returns the project's write key (public, safe in browser code) and a claim link that only the person should open: it signs them in, or makes them an account, and keeps the project with its data. Unclaimed, the project takes up to 10,000 events and is deleted with its data after 7 days. Only call it when the person has not signed in and the other tools ask for sign-in; once signed in, use list_projects and get_project_keys instead.

Parametersnamerequiredplatform

get_start_status

Check a started project

Whether events and errors have arrived for a project started with start_project, by its write key, and whether the person has claimed it yet. Call it after installing the SDK and sending a first event. Projects someone already claimed answer only after sign-in, through get_setup_status.
