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

FAQ
Install corsair and @corsair-dev/companyenrich, add the CompanyEnrich plugin, and connect with an API key. Then call methods like corsair.companyenrich.api.account.me() from your app. Corsair keeps each tenant isolated.
Yes. CompanyEnrich requires an API key from your CompanyEnrich 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 CompanyEnrich, GitHub, Notion, Stripe, and the rest. Trigger CompanyEnrich from a webhook, push updates to Slack, or chain actions across plugins. Same tenant context across integrations, plain TypeScript.
Teams use Corsair for B2B company and people data enrichment — look up firms by domain or properties, find work emails, and search or count companies and people with filters, semantic and lookalike queries. Common builds include sync jobs, admin tooling, and agents that call CompanyEnrich 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 CompanyEnrich 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/companyenrich in the open repo. When CompanyEnrich 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 CompanyEnrich data or hold individual access credentials. Credentials stay in your database. API calls run on your instance. We do not store CompanyEnrich 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 CompanyEnrich on a link in Strict mode and every write waits for your approval, while destructive actions are refused. Every CompanyEnrich operation only reads data, so there are no changes to approve today. You can change a link's mode at hub.corsair.dev/me.
