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

Connect CoinMarketCap in Corsair
Add your CoinMarketCap API key once in Corsair. Corsair stores the credential encrypted and makes the CoinMarketCap API calls for your agent, so it never goes into a prompt or a config file. Connect CoinMarketCap
If your link lets the agent add apps, you can skip this: it gives you a sign-in link the first time it needs CoinMarketCap. On a ChatGPT personal plan, connect CoinMarketCap here first.

https://mcp.corsair.dev/mcpOpen Customize → Connectors → Add custom connector, paste the address, then select Connect.Add a custom MCP server with the address and choose OAuth. Personal plans get read tools only.Add to CursorOr add this to~/.cursor/mcp.json. Cursor opens Corsair to sign in the first time it connects.{ "mcpServers": { "corsair": { "url": "https://mcp.corsair.dev/mcp" } } }Run this, then run/mcpin Claude Code to sign in.claude mcp add --transport http corsair https://mcp.corsair.dev/mcpCodex, 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

FAQ
Install corsair and @corsair-dev/coinmarketcap, add the CoinMarketCap plugin, and connect with an API key. Then call methods like corsair.coinmarketcap.api.cryptocurrency.info() from your app. Corsair keeps each tenant isolated.
Yes. CoinMarketCap requires an API key from your CoinMarketCap 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 CoinMarketCap, GitHub, Notion, Stripe, and the rest. Trigger CoinMarketCap from a webhook, push updates to Slack, or chain actions across plugins. Same tenant context across integrations, plain TypeScript.
Teams use Corsair for crypto market data from CoinMarketCap - ranked market listings, price and volume quotes, ID resolution, asset metadata, global market metrics, price conversion, exchange details, and API key usage. Common builds include sync jobs, admin tooling, and agents that call CoinMarketCap 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 CoinMarketCap 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/coinmarketcap in the open repo. When CoinMarketCap 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 CoinMarketCap data or hold individual access credentials. Credentials stay in your database. API calls run on your instance. We do not store CoinMarketCap 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 CoinMarketCap on a link in Strict mode and every write waits for your approval, while destructive actions are refused. Every CoinMarketCap operation only reads data, so there are no changes to approve today. You can change a link's mode at hub.corsair.dev/me.
