### Description (declared)

# Wombat MCP Bridge

<img src="https://www.wombat-gov.dev/images/WAFpp_upscaled_1000.png" width="120" alt="Wombat logo" align="right">

A secure [Model Context Protocol](https://modelcontextprotocol.io) server that exposes Wombat (Wombat backend) REST endpoints as MCP tools for AI assistants.

## Architecture

sequenceDiagram
    actor User
    participant AI_Client as AI Client (MCP Host)
    participant MCP as wombat-mcp (this bridge)
    participant IdP as Keycloak / IdP
    participant API as wombat-server

    User->>IdP: Authenticate (OIDC/SAML)
    IdP-->>User: IdP tokens
    User->>API: Exchange IdP tokens for Wombat JWT
    API-->>User: Wombat access token

    User->>AI_Client: Start AI session
    AI_Client->>MCP: SSE /sse with Authorization: Bearer <Wombat token>
    MCP->>API: Introspect token (GET /auth/me) or verify HS256 locally
    API-->>MCP: User profile {id, username, role, is_active}

    alt Token invalid
        MCP-->>AI_Client: 401 Unauthorized
    else Token valid
        AI_Client->>MCP: tools/list
        MCP-->>AI_Client: Tools filtered by user's role

        AI_Client->>MCP: tools/call (e.g. list runs)
        MCP->>MCP: Validate arguments against OpenAPI schema
        MCP->>API: Proxy request with same Bearer token
        API-->>MCP: Backend response (row-level auth applied)
        MCP-->>AI_Client: MCP TextContent(result)
    end
```

## Security model

- **IdP-agnostic**: The bridge does not talk to Keycloak/Entra/Okta directly. It trusts tokens issued by the upstream `wombat-server`, which handles the actual OIDC/SAML flows.
- **OIDC pass-through**: The AI client inherits the user's Wombat SSO context by presenting the same Bearer token.
- **Least privilege**: `tools/list` is filtered by the authenticated user's role. Unauthorized tools are invisible.
- **Context propagation**: Every backend call forwards the original `Authorization: Bearer` header so Wombat can apply endpoint- and row-level authorization. When a cal…
