Try Rosette with your agent

Connect Rosette, then paste this into Claude, ChatGPT or Cursor. For ideas from other apps, see the use cases.

Using Corsair, show me what you can do in Rosette on my account, then run one read-only example and show me the result.

Rosette tools and triggers

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

Connect Rosette to Claude, ChatGPT or Cursor

  1. 1

    Connect Rosette in Corsair

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

    If your link lets the agent add apps, you can skip this: it gives you a sign-in link the first time it needs Rosette. On a ChatGPT personal plan, connect Rosette 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. Every Rosette operation only reads data, so it runs right away in every mode.

FAQ

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

Yes. Rosette requires an API key from your Rosette 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 Rosette, GitHub, Notion, Stripe, and the rest. Trigger Rosette from a webhook, push updates to Slack, or chain actions across plugins. Same tenant context across integrations, plain TypeScript.

Teams use Corsair for language detection, entity and relationship extraction, sentiment, topics, semantic vectors, name matching and transliteration with the Rosette text-analytics API. Common builds include sync jobs, admin tooling, and agents that call Rosette 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 Rosette 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/rosette in the open repo. When Rosette 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 Rosette data or hold individual access credentials. Credentials stay in your database. API calls run on your instance. We do not store Rosette 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 Rosette on a link in Strict mode and every write waits for your approval, while destructive actions are refused. Every Rosette operation only reads data, so there are no changes to approve today. You can change a link's mode at hub.corsair.dev/me.
