Installation

pip install prodmcp              # Core (MCP tools, prompts, resources, security)
pip install prodmcp[rest]        # + FastAPI + Uvicorn for the unified server

---

Quick Start

from prodmcp import ProdMCP

app = ProdMCP("MyServer", version="1.0.0")

@app.tool(name="get_user", description="Fetch user by ID")
@app.get("/users/{user_id}")
def get_user(user_id: str) -> dict:
    return {"name": "Alice", "email": "[e-mail]"}

if __name__ == "__main__":
    app.run()  # REST at / (Swagger at /docs) + MCP at /mcp/mcp

Azure AD / Entra ID Integration

ProdMCP ships a zero-boilerplate Azure Active Directory integration at prodmcp.integrations.azure.
It handles JWT validation, JWKS caching, multi-format issuer/audience support, and On-Behalf-Of (OBO) token exchange — in two lines of setup.

Setup

from prodmcp import ProdMCP, Depends
from prodmcp.integrations.azure import AzureADAuth, AzureADTokenContext

auth = AzureADAuth.from_env()          # reads TENANT_ID, BACKEND_CLIENT_ID,
                                       # BACKEND_CLIENT_SECRET, API_AUDIENCE from env
app = ProdMCP("MyServer")
app.add_security_scheme("bearer", auth.bearer_scheme)

Required environment variables

Variable	Description
TENANT_ID	Azure AD tenant GUID
BACKEND_CLIENT_ID	Backend app registration client ID
BACKEND_CLIENT_SECRET	Backend app registration client secret
API_AUDIENCE	Expected aud claim (e.g. api://your-client-id)
OBO_SCOPE	On-Behalf-Of target scope (default: https://graph.microsoft.com/.default)

Protecting routes and MCP tools

@app.tool(name="get_data", description="Authenticated data fetch")
@app.get("/data")
@app.common(security=[{"bearer": []}])
def get_data(ctx: AzureADTokenContext = Depends(auth.require_context)) -> dict:
    ctx.require_role("admin")       # 403 if the user doesn't have the 'admin' role
    obo = ctx.get_obo_token()       # On-Behalf-Of token exchange (downstream API access)
    return {
        "user": ctx.user_info,      # { oid, tid, name, preferred_username, roles, scp }
        "obo_scope": obo.get("scope"),
    }

AzureADTokenContext provides:

Attribute / Method	Description
ctx.token	Raw JWT string
ctx.claims	Full decoded JWT payload
ctx.user_info	Common identity fields (oid, tid, name, roles…)
ctx.roles	List of roles from the JWT
ctx.has_role("admin")	Boolean role check
ctx.require_role("admin")	Raises 403 if role absent
ctx.get_obo_token(scope=...)	On-Behalf-Of exchange

Using with Google ADK (Agent Development Kit)

ProdMCP tools secured with Azure AD work seamlessly with ADK agents.
The Bearer token flows from the REST request → ADK's MCPToolset transport headers → ProdMCP's server-side security check — no extra auth code needed in the agent.

from google.adk.agents import LlmAgent
from google.adk.runners import Runner
from google.adk.sessions import InMemorySessionService
from google.adk.tools.mcp_tool.mcp_toolset import MCPToolset, StreamableHTTPConnectionParams

session_service = InMemorySessionService()

@app.post("/api/chat")
@app.common(security=[{"bearer": []}])
async def chat(request: ChatRequest, ctx: AzureADTokenContext = Depends(auth.require_context)) -> dict:
    # Forward the user's Azure AD token to the MCP server
    toolset = MCPToolset(
        connection_params=StreamableHTTPConnectionParams(
            url=request.mcp_url,
            headers={"Authorization": f"Bearer {ctx.token}"},
        )
    )
    agent = LlmAgent(model="gemini-2.5-flash", tools=[toolset])
    runner = Runner(agent=agent, app_name="myapp", session_service=session_service)
    session = await session_service.create_session(app_name="myapp", user_id=ctx.claims["oid"])

    from google.genai import types
    result_text = ""
    async for event in runner.run_async(
        user_id=session.user_id,
        session_id=session.id,
        new_message=types.Content(role="user", parts=[types.Part(text=request.message)]),
    ):
        if event.is_final_response() and event.content:
            result_text = "".join(p.text for p in event.content.parts if hasattr(p, "text"))

    await toolset.close()
    return {"reply": result_text}

The headers={"Authorization": f"Bearer {ctx.token}"} line is the only auth-specific addition — everything else is standard ADK boilerplate. ProdMCP's _mcp_secured_wrapper handles server-side token extraction transparently.

Running the Example App (prodmcp-masl)

The prodmcp-masl directory contains a full reference implementation: Azure AD authentication + ADK agent + React frontend.

Prerequisites

• Python 3.11+, Node.js 18+
• An Azure AD tenant with:
  • A frontend SPA app registration (public client, no secret)
  • A backend API app registration (with a client secret and exposed API scope)

1. Configure environment

# prodmcp-masl/.env
TENANT_ID=your-tenant-guid
BACKEND_CLIENT_ID=your-backend-app-client-id
BACKEND_CLIENT_SECRET=your-backend-secret
API_AUDIENCE=api://your-backend-client-id
OBO_SCOPE=https://graph.microsoft.com/.default
GEMINI_API_KEY=your-gemini-api-key
ALLOWED_ORIGINS=http://localhost:5173

# prodmcp-masl/frontend/.env.local
VITE_TENANT_ID=your-tenant-guid
VITE_FRONTEND_CLIENT_ID=your-frontend-app-client-id
VITE_BACKEND_SCOPE=api://your-backend-client-id/your-scope-name
VITE_GEMINI_API_KEY=your-gemini-api-key   # optional, can be entered in UI

2. Start the backend

cd prodmcp-masl
python -m venv .venv && source .venv/bin/activate
pip install -r requirements.txt
./run.sh
# → http://localhost:8000
# → Swagger UI: http://localhost:8000/docs
# → MCP endpoint: http://localhost:8000/mcp/mcp

3. Start the frontend

cd prodmcp-masl/frontend
npm install
npm run dev
# → http://localhost:5173

4. Test

Open http://localhost:5173 and sign in with your Azure AD account.

Sidebar — Test API Endpoints:

Endpoint	What to verify
GET /health → Run	Should return {"status": "ok"} with no auth
GET /data → Run	Returns your identity claims + OBO token (200)
GET /data → Run without auth	Returns 401 Unauthorized
GET /api/tools → Run	Lists live MCP tools registered on the server

Sidebar — List Tools: Confirms the MCP server is reachable and tools are registered.

Chat box: Type a message — the ADK agent uses gemini-2.5-flash and invokes get_data via MCP when relevant.

Release Notes

See CHANGELOG.md for the full version history.

v0.3.12 — Pydantic schema fix for secured MCP tools with ADK

Fixes a startup crash when ADK's MCPToolset is used with tools that have user-defined dependency types (e.g. AzureADTokenContext) — @functools.wraps was leaking __annotations__ from the original handler into _mcp_secured_wrapper, causing PydanticSchemaGenerationError.

v0.3.11 — Azure AD / Entra ID integration (prodmcp.integrations.azure)

AzureADAuth, AzureADTokenContext, AzureADBearerScheme — complete Azure AD JWT validation, JWKS caching, multi-format issuer/audience support, role checking, and OBO token exchange in two lines of setup.

v0.3.10 — MCP tool security fix (Bug 10)

ProdMCP-secured MCP tools were raising ProdMCPSecurityError on every ADK/MCP call because __security_context__ was never injected for MCP protocol calls. Fixed via _mcp_secured_wrapper which extracts HTTP headers from FastMCP's Context object.

v0.3.9 — FastMCP lifespan fix (Bug 9)

Fixed RuntimeError: Task group is not initialized caused by FastAPI() being constructed before mcp_instance.http_app(), leaving the FastMCP session manager task group uninitialised.

v0.3.0 — Unified Framework Release

One framework for both REST and MCP. @app.common() for shared config. app.run() for the unified server.
