Overview

AI-generated overview

A time-tracking server that lets an assistant run work timers, log hours per project, apply hourly rates and produce reports, CSV exports and invoice lines.

What you can do
Start, stop and check a single running work timer, with today's total hours and the project it belongs to. Log, edit, list and delete time entries with project, task, tags, notes and hourly rate. Set per-project rates and currencies, and set or check a weekly hours target. Read day, week and per-client summaries and grouped timesheet reports. Export the timesheet to a CSV file and build invoice line items per project and rate. Mark invoiced hours as billed and check or activate a Pro licence.
When to use it
Useful for freelancers and small teams who bill by the hour and want to start timers, log forgotten time and turn tracked hours into reports or invoice lines from chat, without a separate SaaS account.
Requirements
Either the hosted remote endpoint with a bearer token in the Authorization header, or a local install via the .mcpb bundle or a clone-and-build of the repository. The npm package is not yet published, so npx may fail. Local use needs Node.js 18 or later. Data is stored in a local JSON file. A Pro licence key (MCP_LICENSE_KEY or license_activate) is optional.
Before you install
The free tier only reads back the last 7 days for entry lists, reports, CSV exports and invoice summaries, and allows hourly rates on two projects. Deleting an entry is permanent and also removes a billed entry's invoice record, so corrections should use entry_edit. Only one timer runs at a time; starting another stops and logs the previous one. The README states the server makes no network requests and keeps data locally, but the hosted endpoint stores data on a remote service.

Installation

In SourceWeft

  1. Open Pomodoro Timer in the dashboard and add it to a workspace.
  2. Connect Authorization token credentials. They are stored privately and never shown on public pages.
  3. 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/io.github.theluckystrike%2Fpomodoro-timer/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

README

Track time from Claude with a free, no-install server

Featured on Awesome MCP Servers - directory listing | live hosted endpoint, free tier, no signup.

Track billable time without leaving your AI chat. Say "start a timer on the acme redesign", keep working, then ask for "my hours this week by project" or "invoice lines for acme in August". It keeps a running timer, lets you log time you forgot to track, applies your hourly rate per project, and turns the result into a report, a CSV file or a set of invoice line items. Everything is stored as plain JSON on your own machine.

Built by theluckystrike.

In the official MCP Registry (io.github.theluckystrike/time-tracker-timesheet-billable-hours).

Listed on the AI Product Index - live remote endpoint at mcp.zovo.one/s/time-tracker, free tier, no signup.

[time-tracker demo]

Track billable time from chat and turn it straight into a report or invoice line items, zero setup, all local.

60-second install

npm publish for @theluckystrike/mcp-time-tracker is pending. Until then, the .mcpb one-click bundle or a clone+build is the working path, both are verified below.

One-click (.mcpb): download time-tracker.mcpb from the latest release and double-click it in Claude Desktop: https://github.com/theluckystrike/mcp-servers/releases/latest

(claude_desktop_config.json):

json
{  "mcpServers": {    "time-tracker": {      "command": "npx",      "args": ["-y", "@theluckystrike/mcp-time-tracker"]    }  }}

Claude Code:

sh
claude mcp add time-tracker -- npx -y @theluckystrike/mcp-time-tracker

(.cursor/mcp.json):

json
{  "mcpServers": {    "time-tracker": {      "command": "npx",      "args": ["-y", "@theluckystrike/mcp-time-tracker"]    }  }}

The npx form above starts working the moment the package is published. Until then, use the .mcpb bundle above, or build from source with exactly these three commands:

sh
git clone https://github.com/theluckystrike/mcp-servers.git && cd mcp-serversnpm installnpm run build -w packages/mcp-license -w servers/time-tracker

Then point your client's command at node with one arg: the absolute path to servers/time-tracker/dist/index.js.

To run in Pro mode set MCP_LICENSE_KEY in the same config block, or call license_activate once with your key.

Tools

ToolWhat it does
timer_startStart a timer on a project (optional task, tags, rate, currency). Starting a new one stops and logs the old one. A partial project name that matches exactly one existing project is used as that project.
timer_stopStop the running timer, write the entry, return the duration.
timer_statusWhat is running, for how long, and today's total.
entry_addLog time you already worked (start plus end or minutes), with an optional rate and currency: rate "90 euros an hour" bills as EUR 225.00 for 2.5 h. Partial project names resolve like timer_start.
entry_listCompact table of entries, filtered by date range and project.
entry_editChange any field of an entry.
entry_deleteDelete an entry by id.
project_set_rateSet the hourly rate and currency used for money totals (currency accepts codes or words: EUR, euros, pounds, zl). apply_to_existing: true re-rates time already logged for that project; add only_missing: true to touch only entries that carry no rate.
reportHours and money for a period, optionally grouped by project, day, task or tag; omit group_by for the plain total per currency. Table, JSON or CSV. Hours already invoiced are left out; pass unbilled_only: false for the full timesheet.
export_csvWrite entries to a CSV file and return the path.
invoice_summaryInvoice-ready line items for one project: hours, rate, amount, total, in the currency the time was logged in. One line per task and rate, so no line ever shows a blended rate nobody agreed. Returns the entry_ids behind the lines, and skips hours already invoiced (unbilled_only: false includes them). Free for the last 7 days, Pro for any period from full history.
entry_mark_billedStamp the hours that went on an invoice with its number (ids from invoice_summary, or project + from + to), so report and invoice_summary stop offering them and the same hours are never billed twice.
license_statusFree or Pro, and where to upgrade.
license_activateActivate a Pro key (verified offline).

Also exposed: the resource timetracker://today (today's summary) and the prompt daily_standup (writes a standup update from yesterday's and today's tracked time).

What you can say

No tool names required. These are the sentences that were actually tested against the server; the tool column is what answered them.

You sayTool
"Start a timer for the Acme website project."timer_start
"Stop the timer and tell me how long I worked."timer_stop
"What's running right now, and for how long?"timer_status
"Log 2.5 hours yesterday for Acme, design review, at 90 euros an hour."entry_add
"Show me my Acme entries for this week."entry_list
"That last entry should say API refactor, not design review."entry_edit
"Delete the entry I just logged twice."entry_delete
"Set my rate for Acme to 90 EUR an hour."project_set_rate
"How many hours did I bill this month, grouped by project?"report
"Give me invoice lines for Acme in August."invoice_summary
"I invoiced those hours as INV-2026-0001."entry_mark_billed

Two more worth knowing: "export my time to a CSV for my bookkeeper" (export_csv) and "write my standup update from yesterday and today" (the daily_standup prompt).

Worked example

This is a real transcript from the audit in docs/USER_VALUE_R2.md, numbers unchanged.

You: Log 2.5 hours yesterday for Acme, design review, at 90 euros an hour.
  entry_add { project: "Acme", ... }  -> "Acme" resolved to the existing project "Acme website"  -> rate "90 euros an hour" parsed as EUR 90.00/h
Assistant: Logged 2.50 h for Acme website - design review at EUR 90.00/h = EUR 225.00.
You: How much do I bill Acme this week? Give me invoice lines.
  invoice_summary { project: "Acme website", from: "2026-08-31", to: "2026-09-02" }
Assistant: Invoice summary - Acme website  design review    2.50 h   EUR 90.00/h   EUR 225.00  TOTAL            2.50 h                 EUR 225.00

One call each. The rate carries its currency all the way through: the report never prints a bare "225", and it never turns into "$225" by accident.

A second worked example, the weekly report and the daily_standup prompt:

You: How many hours did I put into Acme this week, grouped by task?
  report { project: "Acme website", from: "2026-08-27", to: "2026-09-02", group_by: "task" }
Assistant: Acme website, 2026-08-27 to 2026-09-02  design review   2.50 h   EUR 225.00  TOTAL           2.50 h   EUR 225.00
You: Write my standup update.
  (prompt) daily_standup
Assistant: Yesterday: 2.50 h on Acme website (design review).Today: nothing logged yet.

Billed hours close

An hour that has been invoiced is finished. entry_mark_billed {ids, invoice_number} writes billed_at and billed_invoice onto those entries; from then on report and invoice_summary skip them by default, so next month's "invoice Acme" cannot re-bill work already paid for. The whole timesheet is still there: pass unbilled_only: false to any of them. invoice_summary returns the entry_ids it used precisely so they can be handed straight to entry_mark_billed once the invoice exists.

report and invoice_summary answer overlapping questions on purpose: report is for "how much time and money," grouped any way you like; invoice_summary is for "give me the lines I can put on an invoice," which is a narrower, invoice-shaped view of the same entries for one project.

How it stores data

Entries, projects and rates live in one JSON file: ${XDG_DATA_HOME:-~/.local/share}/mcp-servers/time-tracker/data.json.

Every write (starting or stopping a timer, adding, editing or deleting an entry, setting a rate) happens under an advisory lock file at .../time-tracker/.lock, held across the whole load-mutate-save cycle, so two overlapping calls cannot interleave and corrupt the file. The save itself writes to a temporary file and renames it into place, so a crash or a killed process mid-write leaves either the old file or the new one, never a half-written one. Reads (entry_list, report, timer_status, export_csv) do not take the lock.

To back up your data, copy the single data.json file (and .lock if present, though it holds no data). There is no database and no hidden second file.

If data.json is ever unreadable or not valid JSON, the server does not treat that as "no data yet". It moves the file aside byte-for-byte as data.json.corrupt-<timestamp>, writes a data.json.corrupt marker and makes every tool, reads included, return data file is corrupt; moved to ...; nothing was written. Restore a good data.json (the quarantined copy is right there) and delete the marker file to carry on. Nothing is overwritten in the meantime.

Dates, times and rates

  • Timestamps with no offset are your local time. 2026-09-02T09:00:00 means 09:00 where you are, not UTC. Pass an explicit offset (2026-09-02T09:00:00+02:00) or a trailing Z and it is honoured exactly.
  • Date-only bounds cover whole local days. from: "2026-09-01" is 00:00:00 local on the 1st and to: "2026-09-30" is 23:59:59.999 local on the 30th, so a month reported by dates includes its last day. Timestamps with a time are used as given.
  • Entries are clipped to the window. An entry that starts before from or ends after to counts for the part inside the period, not all of it and not none of it.
  • Entries are split at local midnight for day grouping. Work from 23:30 to 01:30 is 0.5 h on the first day and 1.5 h on the next, including across a month boundary. timer_status counts only the part of an entry, or of the running timer, that falls after midnight today.
  • Rate strings are parsed, never guessed. "1,200 USD" is 1200 (a comma followed by exactly three digits is thousands grouping), "12,50 EUR" is 12.50 (the unambiguous European decimal shape), and "1.200,50" is 1200.50. Anything that could mean either thing, such as "1,2345", is refused with a worked example instead of being read as the wrong number.
  • Rates are captured when the time is logged. entry_add and timer_stop store the effective hourly rate and currency on the entry, and reports and invoices use that stored rate. project_set_rate therefore applies to future entries only; pass apply_to_existing: true to re-rate the time already logged for that project. That re-stamps EVERY entry of the project, including entries that already carry a rate, and the response says how many changed and the project's new total. Add only_missing: true to touch only entries that captured no rate of their own.
  • Tag rows overlap. In group_by: "tag" an entry tagged dev and meeting appears in both rows; the total is computed from the entries once, so it is never the sum of the rows.

Limits and honest caveats

  • Free entry_list, report, export_csv and invoice_summary only see the last 7 days. Timers and entries themselves are unlimited and nothing is ever deleted, the window just narrows what a free call can read back.
  • Free tier supports hourly rates on 2 projects; a third rated project needs Pro.
  • Every report grouping is free, tag included: the tag total is a correctness fix, not a premium feature. group_by itself is optional, omit it for the plain total per currency.
  • Only one timer can run at a time. Starting a second one stops and logs the first, there is no concurrent-timer mode.
  • There is no reminder or idle-detection: if you forget to stop a timer, it keeps running until you stop it or start another.

Troubleshooting

  • npx hangs or fails to find the package: npm publish for this package is pending. Use the .mcpb bundle or the clone-and-build path above until it lands.
  • Using the .mcpb bundle: it installs into Claude Desktop directly; there is no separate path to configure.
  • Using the clone path: the server binary is servers/time-tracker/dist/index.js after npm run build. Point your client's command at node with that absolute path as the only argument.
  • Node version: requires Node >= 18. Check with node -v.
  • Nothing shows up / silent failures: this server writes logs to stderr only, never stdout (stdout is reserved for the MCP protocol). In Claude Desktop, check Settings -> Developer -> the server's log file; in Claude Code, run with --mcp-debug or check the terminal you launched it from.
  • A Pro key isn't recognized: run license_status to see what the server thinks your tier is, and confirm MCP_LICENSE_KEY is set in the same process the client launches (not just your shell).

Privacy

All data stays local: entries live in ${XDG_DATA_HOME:-~/.local/share}/mcp-servers/time-tracker/data.json. The server makes no network requests, has no telemetry, and needs no account. License keys are Ed25519 signatures verified offline against a public key compiled into the package, activation works with no internet connection.

Pairs with

FAQ

Yes. All three speak MCP over stdio with the same config shape; the tools and the data file are identical regardless of client.

Nothing is deleted. The entry stays in data.json forever; it just will not appear in entry_list, report, export_csv or invoice_summary results until you activate Pro, which opens full history.

Yes. Currency is set per project (or per entry, overriding the project default) and every total is grouped by currency, a report never adds EUR and USD together.

The server does not block overlaps; it logs what you tell it. entry_edit lets you fix a mistake after the fact.

No. There are no network calls anywhere in this server, including for license activation, which is verified with a local public key.

One business profile for the whole suite

Your identity is stored once, at ${XDG_DATA_HOME:-~/.local/share}/mcp-servers/profile/business.json, and every server in the suite reads it: the invoice issuer, the docx letterhead, the recurring issuer, expense-tracker's default VAT rate, time-tracker's and timezone's home zone, and the resume and contract letterheads. Set it once with business_set (invoice or docx) - you never repeat it anywhere else. An email address is only ever taken from that profile or from an explicit argument; when none is stored, documents show [add: email] and the tool says so rather than letting anyone improvise an address.

Frequently asked questions

Is there a free MCP time tracking server?

Yes. The time-tracker server at mcp.zovo.one is a free MCP time tracking server with no install: start and stop timers in chat, keep per-client totals, and produce weekly reports. Unlike SaaS trackers (WebWork, TrackingTime) it needs no account - paste the hosted URL and go.

How do I track time from Claude?

Connect https://mcp.zovo.one/mcp/time-tracker (tokenized URL from mcp.zovo.one/mcp/connect) and say: 'Start a timer for the Acme project.' Stop it later the same way; weekly summaries are one ask away.

Use these docs as an MCP server

Any MCP client (Claude, Cursor, Windsurf, VS Code) can read this repository's documentation directly via GitMCP - no install:

license_status

License status

Report this endpoint's licence state for your token as JSON: the product, the tier free or pro, why it is not Pro, and the checkout URL. Call it to explain a free-tier refusal. No arguments, nothing changes.

Takes no parameters.

license_activate

Activate license

Turn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it.

Parameterskeyrequired

timer_start

Start timer

Start a stopwatch for work on a project and return the start time. Only one runs at a time: a new one stops and logs the previous, naming it. rate is an hourly rate in MAJOR units for this timer only.

Parametersratetagstaskprojectrequiredcurrency

timer_stop

Stop timer

Stop the running timer and log it as one entry. Returns the duration, the money at the rate in force and the new entry id. With no timer running it says so and writes nothing.

Parametersnote

timer_status

Timer status

Report the running timer and today's total hours. Today is the local calendar day, so a timer started at 23:30 yesterday contributes only the minutes since midnight. No arguments, and it writes nothing.

Takes no parameters.

entry_add

Add time entry

Log time already worked as one entry and return its id, duration and amount. Give start plus end or minutes. rate is hourly in MAJOR units and is frozen on the entry, so a later rate change never moves it.

Parametersendnoteratetagstaskstartrequiredminutesprojectrequiredbillablecurrency

entry_log
