Ramp tools and triggers

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

    bills.get

  • ListRead-only

    List bills with filters for vendor, status, approval, payment and date ranges, plus cursor paging

    bills.list

  • UpdateWrite

    Update a bill: its internal memo, the memo shown to the vendor, the invoice number or the due date

    bills.update

Transactions

  • GetRead-only

  • ListRead-only

    List card transactions with filters for date, merchant, cardholder, state and approval, plus sorting and cursor paging

Connect Ramp to Claude, ChatGPT or Cursor

  1. 1

    Connect Ramp in Corsair

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

    If your link lets the agent add apps, you can skip this: it gives you a sign-in link the first time it needs Ramp. On a ChatGPT personal plan, connect Ramp 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. None of Ramp's operations are destructive, so in the default Cautious mode they all run right away. Strict mode asks before each of its 4 writes, and Read mode allows reads only.

FAQ

Install corsair and @corsair-dev/ramp, add the Ramp plugin, and connect with an API key or OAuth. Then call methods like corsair.ramp.api.bills.get() from your app. Corsair stores tokens, and keeps each tenant isolated.

Yes. Ramp supports an API key or OAuth. Use credentials or OAuth scopes that match what you automate. Create them in the Ramp developer console, then paste into Corsair or connect through managed auth in Hub.

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

Teams use Corsair for corporate cards and spend management with Ramp - read card transactions, bills, reimbursements, virtual cards, merchants, users and departments, split a transaction into line items, edit a bill and attach memos. Common builds include sync jobs, admin tooling, and agents that call Ramp 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 Ramp 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/ramp in the open repo. When Ramp 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 Ramp data or hold individual access credentials. Credentials stay in your database. API calls run on your instance. We do not store Ramp 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 Ramp on a link in Strict mode and every write waits for your approval, while destructive actions are refused. None of the Ramp operations are destructive, so the default Cautious mode runs them all without asking. You can change a link's mode at hub.corsair.dev/me.
