MCP server for CPFHub.io. Query Brazilian CPF data directly from AI agents.
Connect Cpfhub to Claude, Cursor or any other MCP client and it stops being a tab you switch to. MCP server for CPFHub.io. Query Brazilian CPF data directly from AI agents. The cpfhub mcp server is what makes that connection.
CPFHub.io is a REST API that returns identity data — full name, gender, and date of birth — from any Brazilian CPF number, in ~300ms, with 99.9% uptime and full LGPD compliance.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
get_person_by_cpf — Retrieve identity data (full name, gender, date of birth) from a Brazilian CPF numberget_quota_information — Retrieve remaining API credits and current plan statusFerramenta — DescriçãoCursor — 1. Go to Settings > Features > MCP. 2. Click + Add New MCP Server. 3. Name: CPFHub 4. Type: command 5. Command: exportWindsurf — The Windsurf tool exposed by this serverConfiguration is passed through the environment: CPFHUB_API_KEY, YOUR_API_KEY, OPENAI_API_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
The server ships on npm as @cpfhub/mcp, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Cpfhub's toolset — get_person_by_cpf, get_quota_information, Ferramenta and 2 more — is a fair guide to whether it matches your workflow. It is maintained by cpfhub; worth a glance at recent repository activity before you build anything load-bearing on it.
