How it works

From OpenAPI spec to a live MCP server.

01 · Connection

Connect your API.

Upload your OpenAPI spec and base URL, and the connection gets its own MCP endpoint.

Read the connection docs →
02 · Tool Studio

Shape the tools.

Rewrite the names and descriptions the AI reads, then publish the ones you want.

Read the Tool Studio docs →
03 · Role mapping

Each person gets only their tools.

LockMCP checks the person’s role on every call and records who called which tool.

Read the access docs →
Production-ready, out of the box

Everything your MCP server needs, built in.

No auth plumbing to write. Connect your API, map roles to tools, and you’re live in Claude, ChatGPT and the other AI apps your customers already use.

  • OAuth 2.1 sign-in for every AI client
  • Role-based access to each tool, down to the records a person can see
  • An audit log of who called which tool
  • One MCP endpoint per connection, hosted for you

Pick how your users sign in. Whichever you choose, the agent never gets a standing credential for your API.

We host the sign-in. Zero setup.

Invite your users and they sign in on LockMCP. Nothing to build or integrate on your side, so it’s the fastest way to get started.

  • Works with every AI client
  • Invite users by email
  • Best if you don’t have an identity provider
User → LockMCP sign-in → your API
