The MCP you didn't realise you needed, or wanted but didn't know who to ask, is here. Building on over 100k ecosystem downloads (latest stats), we bring you faf-mcp to cure your syncing pain and fuel your chosen AI with optimized context, on-demand.

⭐ Bookmarks it for you, helps other devs find it too.

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"]}}}

Run It

faf-mcp runs locally over stdio. Point your IDE at one of these commands.

Interop Tools

# 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:

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

• --all flag 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

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.

29 MCP Tools

Plus CLI fallback (via faf-cli):

• faf readme - Extract 6 Ws from README (+25-35% boost)

• faf human-add - Non-interactive YAML merge (6Ws Builder)

• faf git - GitHub repo analysis without cloning

• And 40+ more commands...

Ecosystem

• claude-faf-mcp — Claude Desktop (33 tools)

• faf-cli — Terminal CLI

• faf-wasm — WASM SDK (<5ms scoring)

• faf-wasm-gen — Rust→WASM project.faf generator, browser/edge (faf-wasm's generate sibling)

• faf-trinity — reference MCP server exposing all three IANA FAF formats (context/memory/agent) together

• faf.one — Official website

• docs/SKILLS-OVER-MCP.md — J1 Agent Skill faf-ide (stdio · skills/list · digests)

If faf-mcp has been useful, consider starring the repo — it helps others find it.
