RudderStack Transformations tools and triggers

Tools are what your agent can do in RudderStack Transformations through Corsair's MCP server. Triggers are the RudderStack Transformations events a routine can start from.

Transformations

  • ConnectWrite

    Connect a published transformation to a destination, replacing any transformation already connected to it

    transformations.connect

  • CreateWrite

    Create a transformation; unpublished unless publish is true, and only a published one can be connected to a destination

    transformations.create

  • DeleteDestructive

    Delete a published transformation; its revisions are never deleted

    transformations.delete

  • DisconnectWrite

    Disconnect a transformation from a destination

    transformations.disconnect

  • GetRead-only

    Read one published transformation by ID

    transformations.get

  • Get VersionRead-only

    Read one revision of a transformation

    transformations.getVersion

  • ListRead-only

    List the published transformations in the workspace with their code, language and connected destinations

    transformations.list

  • List VersionsRead-only

    List the revisions of a transformation, newest or oldest first

    transformations.listVersions

  • UpdateWrite

    Update a transformation, which always writes a new revision and makes it live only when publish is true

    transformations.update

Libraries

  • CreateWrite

    Create a reusable library whose importName transformations import it by

    libraries.create

  • DeleteDestructive

    Delete a library by ID

    libraries.delete

  • GetRead-only

    Read one published library by ID

    libraries.get

Connect RudderStack Transformations to Claude, ChatGPT or Cursor

  1. 1

    Connect RudderStack Transformations in Corsair

    Add your RudderStack Transformations API key once in Corsair. Corsair stores the credential encrypted and makes the RudderStack Transformations API calls for your agent, so it never goes into a prompt or a config file. Connect RudderStack Transformations

    If your link lets the agent add apps, you can skip this: it gives you a sign-in link the first time it needs RudderStack Transformations. On a ChatGPT personal plan, connect RudderStack Transformations here first.

  2. 2

    Add Corsair's MCP server to your agent

    Every client uses the same address:

    https://mcp.corsair.dev/mcp
    Open Customize → Connectors → Add custom connector, paste the address, then select Connect.

    Codex, Gemini CLI, VS Code, Zed and other clients with OAuth sign-in work the same way. Clients without it, such as GitHub Copilot's coding agent, use a link's own address and an API key. Setup for every client

  3. 3

    Sign in and choose what needs your approval

    Your client opens Corsair to sign in. Pick a link: the apps your agent can use and a mode that decides what it may do without asking. In the default Cautious mode, RudderStack Transformations's read and write operations run right away and its 2 destructive operations wait for your approval. Strict mode asks before every write and refuses destructive operations, and Read mode allows reads only.

FAQ

Install corsair and @corsair-dev/rudderstacktransform, add the RudderStack Transformations plugin, and connect with an API key. Then call methods like corsair.rudderstacktransform.api.libraries.create() from your app. Corsair keeps each tenant isolated.

Yes. RudderStack Transformations requires an API key from your RudderStack Transformations account or developer dashboard. Create credentials with access that matches what you automate, then paste them into Corsair or connect through managed auth in Hub.

Yes. One Corsair client can hit RudderStack Transformations, GitHub, Notion, Stripe, and the rest. Trigger RudderStack Transformations from a webhook, push updates to Slack, or chain actions across plugins. Same tenant context across integrations, plain TypeScript.

Teams use Corsair for create, version, publish and connect RudderStack transformations, and manage the reusable libraries they import. Common builds include sync jobs, admin tooling, and agents that call RudderStack Transformations APIs from your backend.

The SDK is open source. Self-host and you pay Corsair nothing for the integration layer. Hub bills for hosted auth and execution, not per RudderStack Transformations API call. Hub has a generous free tier. For hobby projects you can probably run the whole thing on free. Paid plans start to matter with more tenants or heavier traffic.

We maintain @corsair-dev/rudderstacktransform in the open repo. When RudderStack Transformations ships API changes, upgrade the package. Your call sites stay typed. You should not need to rewrite the integration layer each time.

No. Corsair does not read your RudderStack Transformations data or hold individual access credentials. Credentials stay in your database. API calls run on your instance. We do not store RudderStack Transformations data on your behalf.

Yes. Add https://mcp.corsair.dev/mcp as a custom connector or MCP server in Claude, ChatGPT, Cursor, VS Code, Claude Code, Codex or any client that supports remote MCP servers with OAuth sign-in, then sign in to Corsair. On ChatGPT personal plans, custom servers currently get read tools only.

Yes. Put RudderStack Transformations on a link in Strict mode and every write waits for your approval, while destructive actions are refused. The default Cautious mode asks only before the 2 destructive RudderStack Transformations operations. You can change a link's mode at hub.corsair.dev/me.
