PyPI version Documentation status

An MCP (Model Context Protocol) server is how AI agents — Claude Code, ChatGPT, and the assistants built on them — connect to your application in a controlled way: they see and call only the tools you choose to expose, under the permissions you enforce. As your users lean on AI for more of their work, it pays to be ready to accommodate their agents without loosening the protections Django already gives your data and infrastructure — and that is what this package is for.

django-stateless-mcp is a stateless MCP server for Django, built on the 2026-07-28 spec. An MCP endpoint becomes an ordinary Django view — no sessions, no SSE, no sticky routing, and no dedicated single-process service.

Why use this

  • Your MCP server is an ordinary Django view — same deployment, same middleware, same monitoring, and tools call your models and business logic directly. No separate MCP service to build, secure, and operate.

  • It scales like the rest of your Django app — any worker on any instance can serve any request, including an elicitation answer. See Why stateless for what changed on 2026-07-28 to make that possible.

  • Tools can ask the user questions — fill in missing form fields, or require explicit confirmation before an update or delete, resuming on whichever worker the answer lands on: request_state_security() keys the resume state from SECRET_KEY. See the elicitation recipe.

  • Kick off a long job, keep chatting, and the result comes back when it's ready — see the long-running jobs recipe.

  • Your authentication and permissions work inside tools — bearer auth resolves to a real Django user, so user.has_perm(...) just works, and PermittedToolsFilter hides tools a user may not use from tools/list.

  • You can see what your MCP is doing — optional structlog middleware logs one queryable event per request.

  • Tools register the Django way — each app's mcp.py is discovered automatically, exactly like admin.py.

Usage

# myproject/mcp.py
from mcp.server.mcpserver import MCPServer

from django_stateless_mcp import request_state_security

server = MCPServer(
    name="my-server",
    version="1.0.0",
    request_state_security=request_state_security(),
)


@server.tool()
def add(a: int, b: int) -> int:
    """Add two integers."""
    return a + b
# urls.py
from django.urls import path

from django_stateless_mcp import mcp_view
from myproject.mcp import server

urlpatterns = [path("mcp/", mcp_view(server))]

That is the whole integration. The endpoint runs under both WSGI and ASGI.

What it provides

  • mcp_view(server) — serve an MCPServer as a stateless streamable-HTTP Django view, optionally requiring OAuth bearer auth via a token_verifier.

  • mcp.py autodiscovery — add django_stateless_mcp to INSTALLED_APPS and each app's mcp.py registers tools, like admin.py.

  • request_state_security() — key the SDK's elicitation-resume encryption from SECRET_KEY, so elicitation survives a multi-worker deployment.

  • django_request(ctx) — reach the authenticated Django request from inside a tool, with no global state.

  • StructlogRequestLogger — optional flow-logging middleware.

  • Subscription streams — clients can subscribe to server-pushed events under ASGI; under WSGI the endpoint declines cleanly rather than pinning a worker.

Tool registration, elicitation, resources and prompts are the MCP SDK's own API; this package is the Django layer around it.

Supported versions

  • Python 3.10–3.14 (3.10 and 3.11 with Django 5.2 LTS only, matching Django's own support)

  • Django 5.2 LTS and 6.0

  • mcp 2.0.x

Each is exercised in CI, along with an advisory job tracking the SDK's git main.

Try it live

The repo ships a runnable example project. docker compose up starts it behind four worker processes (no local uv or Python needed; just demo-asgi is the host-run equivalent); the example README quick start walks through watching an elicitation started on one worker resume on another — the package's thesis, observable with curl or any MCP client.
