contactapi
An open-source API to save contacts. Send a POST with an email and any other JSON fields you want, and they get saved as-is. Manage them with simple CRUD.
Built with Hono and deployed on Vercel.
- Landing page & docs — /
- Log in — /login
- Sign up — /signup
- LLM-friendly docs — /llms.txt
API overview
The base URL is https://contactapi.dev and every request carries your API key as a Bearer token:
Authorization: Bearer YOUR_KEYContacts are keyed by email — creating one whose email already exists updates it in place rather than duplicating it. Full reference lives on the landing page and in /llms.txt.
There are two kinds of key:
locked to your domains.
- cksecret… — secret key, for your backend. Full access to every endpoint.
- ckpub… — publishable key, for the browser. Can only create contacts and is
MCP server
AI clients (Claude Desktop, claude.ai custom connectors, Cursor, the MCP Inspector) can manage your contacts through an MCP server at:
https://contactapi.dev/mcpAuth is OAuth 2.1 with dynamic client registration — point a client at the URL and it discovers the authorization server, registers itself, and sends you to log in and approve access; no API key to copy. The server exposes five tools that mirror the REST API: listcontacts, getcontact, createcontact (upsert-by-email), updatecontact, and delete_contact. Everything is scoped to the account you log in as.
The OAuth provider is Better Auth's mcp plugin (src/auth.ts); the tools and endpoint wiring live in src/mcp/server.ts and src/index.ts.
