Connect your MCP server as assistant tools
Register your MCP server as your assistant's tools, give each tool an access level, mark the changes that need a confirmation card, then publish.

AI Assistant turns your MCP server into your mate's tools. MCP (the Model Context Protocol) is an open standard for giving an AI assistant tools over HTTPS. Register your server, give every tool one of three access levels, flag the writes that should ask first, choose how your server learns who the customer is, then probe, check and publish. Your server keeps the data; your mate only calls it.
What you build
An MCP server that serves tools/list with input schemas and answers tools/call. The one rule that makes it safe: your server works out the customer only from the verified bearer — never from an account id in a tool's arguments. Every tool gets one of three access levels plus an optional confirmation step; see Connecting your systems for the levels and the Glossary for the words.
1. Expose the server
- Serve it over HTTPS at a stable URL, reachable from the public internet.
- Speak JSON-RPC 2.0 over streamable HTTP (
http) or server-sent events (sse). - Return a name, description and JSON schema per tool on
tools/list. Public tools need no bearer; identified and delegated calls carry one.
2. Choose how your server knows the customer
<!-- The technical delegation table above keeps its developer register; every term is defined at first use or in the glossary. -->Questions
Does your mate see my customers' data?
Only what your server returns for the verified bearer. Your server enforces the scope; your mate never receives more than it hands back.
Can the model pass another customer's id?
It can try; your server ignores it. The customer comes from the bearer's signed subject, never from a tool's arguments.
Signed actor token or per-customer OAuth?
The signed proof when your product already verified the visitor. OAuth when a separate consent screen is the point.
Who gives me the verifier secret?
You do. Set it on the connection (Console → Connections, or ) and install the same value in your server.
