MCP.Pizza Chef: jitsucom

This tool watches what happens on your website or app — page visits, button clicks, purchases — and automatically routes that information to wherever you want to use it, such as a spreadsheet, a database, or a marketing tool. It works as a free, self-run alternative to Segment. Connect it to Claude Desktop, Cursor, or VS Code, and your assistant can create new connections, test that data is flowing correctly, and fix problems along the way. You'll need a free account and a connection key to get started.

What is Jitsu?

Jitsu collects event data from your websites, apps and servers, and delivers it to your data warehouse and to whatever other tools you use. It covers the same ground as Segment, but it's MIT-licensed and self-hostable, so the whole pipeline can run inside your own infrastructure — or on Jitsu Cloud, same software, hosted.

Data lands in minutes, not hours: Segment loads warehouses once or twice a day (hourly at best), while Jitsu delivers per destination in batches as frequent as a minute, or row-by-row where that suits the destination. And where Segment bills by Monthly Tracked User, Jitsu Cloud bills by event volume, so the bill tracks data rather than audience size — while self-hosting has no usage billing at all.

A typical Jitsu setup gives you:

  • Event collection from the browser, mobile, or the server, via SDKs, an HTTP API, or a drop-in Segment proxy.
  • Delivery to destinations — ClickHouse, BigQuery, Snowflake, Redshift, Postgres, S3, GCS, and dozens of SaaS tools, streamed or micro-batched depending on what the destination prefers. See the destination catalog.
  • Functions — JavaScript that runs on every event to filter, transform, and enrich it before delivery.
    • Write them in the browser, or build and deploy them from your own repo with the Jitsu CLI — jitsu-cli init scaffolds a TypeScript project with tests, and jitsu-cli deploy ships it to your workspace. Use whatever tooling you like: TypeScript, npm libraries, your own test suite, and your normal CI.
  • Connector syncs — pull data into your warehouse from third-party sources (Airbyte-compatible connectors).
  • A user identity graph and profile builder, built automatically from the event stream.
  • Live Events — see every event, function log and destination write as it happens, which makes debugging a pipeline a matter of seconds rather than days.
  • An MCP server, so an AI agent can configure and operate all of the above.

jitsu FAQ

Can I use this to track what people do on my website?
Yes — it watches page visits, clicks, and other activity on your website or app, then sends that information wherever you want it to go.
Can I use this to send that data into a spreadsheet or database?
Yes — you can connect it to a spreadsheet, a database, or dozens of other everyday tools, and choose how often the data updates.
Which apps can I use this with?
It works with Claude Desktop, Claude Code, Cursor, and VS Code, and connects the same way in each — you add one web address to your assistant's settings.
Do I need an account or a key to use this?
Yes — you'll need a free account and a connection key from the service. Once you have one, your assistant handles the rest.
How hard is it to set up?
Setup is quick: add a single web address to your assistant's settings, and the first request opens a browser tab for you to approve the connection. Nothing to install and no code required.
Is this free to use?
There's a free plan that includes 200,000 tracked visits or events a month, with no credit card required to start.
Can my AI assistant fix problems with my tracking on its own?
Yes — it can check the live activity log, notice when something isn't working, and correct the setup itself, instead of you having to dig through settings.
Do I need to know how to code to use this?
No — you describe what you want in plain language, and your assistant sets up the connections and destinations for you. Advanced users can write their own small pieces of custom logic, but that's optional.
