# Internal MCP Servers

> Connect internal services with identity-scoped access through Char

<Note>
  **Private Beta** — [Contact us](mailto:alex@mcp-b.ai?subject=Internal%20MCP%20Connectors) to get set up.
</Note>

Internal MCP connectors let your users access internal tools with their own identity context.

## How identity reaches internal MCP

    App->>IDP: User authenticates
    IDP-->>App: ID Token
    App->>Agent: connect({ publishableKey, idToken })
    Agent->>Hub: Connect with org + user identity
    Hub->>IDP: Token exchange
    IDP-->>Hub: Scoped assertion/token
    Hub->>MCP: tools/call with scoped token
    MCP-->>Hub: Result
    Hub-->>Agent: Result
```
