Documentation Overview
.FAF Context
Persistent Project Context for Cursor, IDEs and VS Code. Define once. Sync everywhere. npm: faf-mcp
Home: wolfe-jam.github.io/faf-mcp · Hosted MCP endpoint: https://ide.faf.one/mcp/v1 (Streamable HTTP)
The MCP you didn't realise you needed, or wanted but didn't know who to ask, is here. Building on 100,000+ downloads across the FAF ecosystem, we bring you faf-mcp to cure your syncing pain and fuel your chosen AI with optimized context, on-demand.
⭐ A star helps other devs discover faf-mcp — despite the downloads, ~3 of 4 devs check stars first.
What's New in 2.3.0 — The Curated Edition
The tools you actually need, up front. faf-mcp now leads with 15 essential tools by default — a clean, focused surface instead of a wall of options. Need everything? Set FAF_TOOLS=all for the full 29 (every tool stays callable by name either way). And every Core tool's description was rewritten so your AI picks the right one, first time.
Define once. Sync everywhere.
You maintain .cursorrules. Your teammate uses AGENTS.md. Someone on the team just switched to Gemini. Every AI tool wants its own context file — and they all say the same thing in different formats.
faf-mcp is the dedicated MCP server for Cursor, Windsurf, Cline, VS Code, and every non-Claude platform. One .faf file in your repo, synced to every format your team needs.
Context for Cursor & IDE agents: faf-cli (v7.1) authors the files this server syncs — bunx faf export --agents, zero-install and git-native. See FAF-CLI for Cursor & IDE agents 👀.

Quick Start
Cursor — one click: 
Everywhere else:
bunx faf-mcp
Add to your MCP config:
{"mcpServers": {"faf": {"command": "bunx", "args": ["faf-mcp"]}}}
| Platform | Config File |
|---|---|
| Cursor | ~/.cursor/mcp.json |
| Windsurf | ~/.codeium/windsurf/mcp_config.json |
| Cline | Cline MCP settings |
| VS Code | MCP extension config |
| Claude Desktop | Use claude-faf-mcp |
Three Ways to Deploy
| Door | Method | Best For |
|---|---|---|
| Hosted | mcpaas.live | Zero-install, point any MCP client to the URL |
| Self-Deploy | Deploy to Vercel | Your own instance, full control |
| Local | bunx faf-mcp | IDE integration via stdio transport |
Hosted (mcpaas.live)
Point your MCP client to https://ide.faf.one/mcp/v1 — no install, no config, no maintenance. Served from 300+ Cloudflare edges with sub-ms cold starts via 2.7KB Zig-WASM engine.
Self-Deploy (Vercel)
Deploy your own MCP server on Vercel in one click. Once deployed, your server exposes:
/health— Health check/info— Server metadata + tool list/mcp/v1— MCP Streamable HTTP transport
Local (npm)
npx faf-mcp
Interop Tools
| Tool | Platform | Action |
|---|---|---|
faf_agents | OpenAI Codex | Import/export/sync AGENTS.md |
faf_cursor | Cursor IDE | Import/export/sync .cursorrules |
faf_gemini | Google Gemini | Import/export/sync GEMINI.md |
faf_conductor | Conductor | Import/export directory structure |
faf_git | GitHub | Author .faf from any repo URL |
# Sync to all formats at once
faf bi-sync --all
# Generate .faf from any GitHub repo
faf_git { url: "https://github.com/facebook/react" }
Core tier: 15 essential tools shown by default; set FAF_TOOLS=all for the full 29 (every tool stays callable by name either way) · with CLI fallback · 9 test suites · 7 bundled parsers
Cloud Sync
Share your FAF context globally via mcpaas.live:
| Tool | Purpose |
|---|---|
faf_cloud_publish | Upload to cloud, get shareable URL |
faf_cloud_fetch | Pull context from cloud |
faf_cloud_list | List available souls |
faf_cloud_search | Search across souls |
faf_cloud_share | Generate share links |
Example Workflow:
# Upload your project.faf
faf_cloud_publish { soul_name: "my-project" }
→ https://mcpaas.live/souls/my-project
# Anyone can fetch it
faf_cloud_fetch { soul_name: "my-project" }
→ Context merged into local project.faf
Zero-install sharing - Recipients need no MCP setup. Served from 300+ Cloudflare edges with <1ms cold starts via 2.7KB Zig-WASM engine.
Eternal Bi-Sync
Your .faf file and your platform context files stay synchronized in milliseconds.
project.faf ←── 8ms ──→ .cursorrules / AGENTS.md / CLAUDE.md / GEMINI.md
Single source of truth
- Update either side → both stay aligned
--allflag syncs to all four formats at once- Zero manual maintenance
- Works across teams, branches, sessions
AI assistants forget. They drift. Every new session, AI starts guessing again. Bi-sync means context never goes stale.
Tier System: From Blind to Optimized
| Tier | Score | Status |
|---|---|---|
| 🏆 TROPHY | 100% | AI never has to guess |
| ★ GOLD | 99%+ | 1 slot from Trophy |
| ◆ SILVER | 95%+ | Close — keep going |
| ◇ BRONZE | 85%+ | Interim — keep going |
| ● GREEN | 70%+ | Interim — keep going |
| ● YELLOW | 55%+ | AI flipping coins |
| ○ RED | <55% | AI working blind |
| ♡ WHITE | 0% | No context at all |
At 55%, AI is guessing half the time. At 100%, AI is optimized.
use>faf | Prompt Pattern
Start every prompt with "Use FAF" to invoke MCP tools:
Use FAF to initialize my project
Use FAF to score my AI-readiness
Use FAF to sync my context
Use FAF to enhance my project
Works on all platforms — stops web search, forces tool usage.
