Warframe MCP

FastMCP server for Warframe.market, WarframeStat.us, and Overframe.gg builds.

Remote host (ChatGPT skill) — free options

Honest take: there is no truly free always-on generic Docker host that matches Cloudflare Containers without a card / paid plan. For this FastMCP project, the best free path is a managed MCP host, not a general PaaS.

Recommended: Prefect Horizon (free personal tier)

Live URL: https://warframe.fastmcp.app/mcp
Org: snakeplisken47 · repo: Ma110w/WarframeSkill · auto-deploys from main

Built by the FastMCP team. Free for personal projects, GitHub deploy, HTTPS URL like https://<name>.fastmcp.app/mcp.

Horizon authentication is enabled on the free tier (Bearer / OAuth). Fully public “Auth: None” needs a paid Developer plan.

ChatGPT (OAuth):

1. Enable Developer mode → create a connector / app
2. Auth: OAuth
3. MCP Server URL: https://warframe.fastmcp.app/mcp
4. Complete the Horizon sign-in when prompted (must be a member of org snakeplisken47)

Other clients: use the URL above; interactive clients open Horizon sign-in, or send Authorization: Bearer fmcp_... from a Horizon API key.

Docs: Connect a client · Authentication

Handshake hardening in this repo (FASTMCP_STATELESS_HTTP + immediate 202 on notifications/*) still applies on Horizon.

Other free-ish options (tradeoffs)

Option	Cost	Fit for ChatGPT MCP
Prefect Horizon	Free personal	Best match — FastMCP-native
mcphosting.io	Free tier	Already tried; notifications/initialized hung → Cloudflare 502
Google Cloud Run	Free tier (scale-to-zero)	Works with our Dockerfile; cold starts can break picky clients
Render free	Free	Sleeps after ~15m idle → bad for connectors
Railway	Trial / limited credits	Not permanently free
Cloudflare Containers	Workers Paid $5/mo	Works well; canceled on this account (ends Aug 30, 2026)

Cloudflare Worker warframe-mcp was deleted after cancel. Repo still has optional Container scaffolding (Dockerfile, wrangler.toml, GH Actions) if you ever re-enable Paid.

Horizon-style / mcphosting entrypoint

Entrypoint object: server.py → mcp. Dependencies: requirements.txt. Do not add a Procfile or second runner.

Local (optional, Cursor only)

pip install -r requirements.txt
python server.py

Cursor stdio example:

"warframe": {
  "command": "M:\\WarframeSkill\\.venv\\Scripts\\python.exe",
  "args": ["M:\\WarframeSkill\\server.py"]
}

Tools

ping, market tools (wfm_*), worldstate tools (ws_*), Overframe tools (of_*), Platinum CAD tools (plat_*).

Overframe flow

1. of_search_items — same idea as the site search box (item → Overframe id)
2. of_list_builds — builds for that item (optional title filter)
3. of_get_build — full build with resolved mod names / ranks / drain
4. of_top_mods — most-used mods for an item

If static DB loads start failing after an Overframe frontend deploy, set OVERFRAME_WEBPACK_URL to the current https://static.overframe.gg/_next/static/chunks/webpack-*.js URL from the site.

Platinum → CAD (Ontario)

Pack list prices from WARFRAME Wiki: Platinum. Tax defaults to Ontario HST 13% added at checkout (Steam-style).

1. plat_list_packs — available packs + CAD/USD for pc/xbox/playstation
2. plat_price_pack — one pack with tax / optional coupon
3. plat_recommend_packs — cheapest pack combo to reach a platinum target
4. plat_to_cad — estimate CAD cost for N platinum via store packs
