remote-mcp 0.1.0

One command to a production-ready remote MCP server

remote-mcp

One command to a production-ready remote MCP server.

---

Building a remote MCP server means solving the same hard problems every time: OAuth pass-through, RFC 8414/9728 discovery endpoints, middleware stack, telemetry, retry logic, and a test suite that passes on day one.

remote-mcp scaffolds all of it from two prompts. Generated projects have zero runtime dependency on this package — every file is yours to read, audit, and modify.

Install

pipx install remote-mcp   # recommended
# or
pip install remote-mcp

Usage

remote-mcp new my-project

  FastMCP Remote Server Generator

  Project name    [my-project]:
  Service name    [My Project]:

  Scaffolding my-project...  ✓

  Done! Next steps:
    cd my-project
    python -m venv venv && source venv/bin/activate
    pip install -e ".[dev]"
    cp env.example .env
    uvicorn asgi:application --reload --port 8001 --lifespan on

Server is live at http://localhost:8001. MCP endpoint: http://localhost:8001/sse.

Included infrastructure

Module	What it provides
core/auth.py	extract_bearer_token(ctx) — forward Bearer token verbatim to your backend
core/http_client.py	api_get, api_post — pooled httpx client with tenacity retry
core/errors.py	MyProjectError + Auth, Forbidden, Validation, Backend, RateLimit subclasses
core/telemetry.py	Rotating JSONL log, user IDs hashed (SHA-256, non-reversible)
core/handlers.py	@tool_handler — catches errors, formats responses, records telemetry
server.py	CORS → Auth → Telemetry middleware, RFC 8414 + RFC 9728 discovery, landing page

Nothing is forced on you. Delete what you don't need.

Adding a tool

Open src/tools/example.py — it's already wired up as a working echo tool. Replace it or add alongside it:

# src/tools/my_tool.py
from fastmcp import FastMCP, Context
from src.core.handlers import tool_handler, get_client_and_token

my_router = FastMCP("my-tool")

@my_router.tool()
@tool_handler
async def my_tool(param: str, ctx: Context) -> str:
    client, auth_header = await get_client_and_token(ctx)
    response = await client.get("/some/endpoint", headers={"Authorization": auth_header})
    return response.json()

Mount it in src/server.py:

from src.tools.my_tool import my_router
mcp.mount(my_router)

How it works

remote-mcp renders Jinja2 templates into your project directory at scaffold time. After that, it's gone — no version pinning, no update command, no hidden runtime. You own every line.

Requirements

• Python ≥ 3.12
• FastMCP ≥ 3.0 (installed in the generated project, not this package)
