Overview

AI-generated overview

Remote MCP server for cookieless web analytics that an AI agent can create and query: sites, goals, funnels, revenue and read-only SQL.

What you can do
  • Create and manage analytics sites and tracking configuration
  • Query traffic data by country, region, city, channel, UTM and ad click ids
  • Define and inspect goals, funnels, revenue and realtime activity
  • Run read-only SQL against the collected event data
  • Send server-side events and verify results through the API
When to use it
Useful when an agent needs to set up web analytics for a site without a signup form or dashboard, or to pull traffic, conversion and revenue numbers into a conversation. Also fits agents that want to check their own tracking setup end to end.
Requirements
Remote streamable HTTP endpoint at analytics.agentfirststack.com. Authentication is required: an Authorization header carrying a bearer API key, obtained from a single POST to the provider's signup endpoint, or OAuth. No local runtime or package install.
Before you install
The Authorization header carries a long-lived API key that works across the provider's services, so treat it as a secret. The hosted service has fair-use limits. Creating sites and sending events writes data to a third-party service; self-hosting requires a Cloudflare account and API token.

Installation

In SourceWeft

  1. Open AgentFirstStack Analytics in the dashboard and add it to a workspace.
  2. Connect the required 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/com.agentfirststack%2Fanalytics/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. The client completes OAuth sign-in on first connect.

AgentFirstStack

Analytics, tag management, email inboxes and session replay that an AI agent sets up by itself.
No signup form, no verification email, no dashboard to click through. Free to use, and open source.

[CI] [AGPL-3.0 license]

Every new website needs the same infrastructure: analytics, a tag manager with conversion tracking, and an email address to sign up for everything else. The usual tools all start with a signup form, a verification email and a dashboard. Coding agents can't get past those steps alone.

AgentFirstStack is that infrastructure, rebuilt so an agent can do the whole job:

  • One request gets an account. POST /v1/signup returns a key that works on every service.
  • Everything is an API call and an MCP tool. Nothing is hidden behind a settings page.
  • The manual is a text file. Each service serves /llms.txt with every endpoint, tool and field.
  • Every step can be verified. The agent checks its own work instead of guessing.
  • Humans optional. When it's done, the agent hands its person a claim link. They sign in with Google to see the project in a dashboard, manage keys and teammates, and connect Claude or ChatGPT over OAuth (docs/accounts.md).

TagsA tag manager and server-side conversion router. Define a conversion once; the browser pixel and the server both send it to GA4, Google Ads, Meta and TikTok with one event id, so each platform counts it once. Scan, validate, preview, test and publishGoogle Tag Manager, server-side GTM

Quick start

Hosted (free)

Copy the prompt from agentfirststack.com into Claude Code, Cursor, Codex or any agent that can make HTTP requests. Or do it by hand:

sh
curl -X POST https://agentfirststack.com/v1/signup# { "api_key": "afs_...", "mcp": { ... }, "next_steps": [ ... ] }
curl -X POST https://analytics.agentfirststack.com/v1/sites \  -H "Authorization: Bearer $AGENTFIRSTSTACK_API_KEY" -H 'content-type: application/json' \  -d '{"domain":"example.com"}'

Add one MCP server for every service (tools prefixed analytics_, tags_, mail_, replay_):

sh
claude mcp add --transport http afs https://agentfirststack.com/mcp --header "Authorization: Bearer $AGENTFIRSTSTACK_API_KEY"

Or one per service:

sh
claude mcp add --transport http afs-analytics https://analytics.agentfirststack.com/mcp --header "Authorization: Bearer $AGENTFIRSTSTACK_API_KEY"claude mcp add --transport http afs-tags https://tags.agentfirststack.com/mcp --header "Authorization: Bearer $AGENTFIRSTSTACK_API_KEY"claude mcp add --transport http afs-mail https://mail.agentfirststack.com/mcp --header "Authorization: Bearer $AGENTFIRSTSTACK_API_KEY"claude mcp add --transport http afs-replay https://replay.agentfirststack.com/mcp --header "Authorization: Bearer $AGENTFIRSTSTACK_API_KEY"

The hosted version has fair-use limits, listed in the manual.

Self-hosted

Everything runs on Cloudflare Workers in your own account:

sh
git clone https://github.com/StartGlobal-AI/agentfirststack && cd agentfirststackpnpm installpnpm afs init mystack --domain example.com --account <cloudflare-account-id>pnpm afs deploy mystackCLOUDFLARE_API_TOKEN=... pnpm afs email mystack     # inbound + outbound mailpnpm afs check mystack

See docs/self-hosting.md for requirements, signup modes, limits and updates.

How it's built

TypeScript on Cloudflare Workers with Hono and zod. Storage:

  • D1: configuration and the shared identity database.
  • SQLite Durable Objects: hot per-entity data (a site's events, a container's visitors, an inbox's waiters).
  • R2: mail blobs and replay recording chunks.
  • Queues: retried delivery to ad platforms and webhooks.
  • Email Routing and Email Sending: mail in and out.

Development

docs/development.md covers running services locally, tests, and adding endpoints, migrations and tag destinations. docs/operations.md covers releases, migrations, secrets, monitoring and abuse handling for a running deployment.

Contributing

Issues and pull requests are welcome. Read CONTRIBUTING.md first; it's short. Report security issues privately as described in SECURITY.md.

License

The services are AGPL-3.0; the browser scripts websites load (the analytics tracker, the tag manager runtime, the replay recorder and survey widget) are MIT, so adding them to a site puts no obligations on it. Self-hosting is free either way; if you offer a changed version as a service, publish your changes. Details: LICENSING.md. Built and hosted by StartGlobal.

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
