[![Business card · Get yours →](https://wolfe-jam.github.io/agent-business-card/badge.svg)](https://wolfe-jam.github.io/agent-business-card/?repo=Wolfe-Jam/grok-faf-mcp)

**FAF defines. AGENTS.md instructs. AI codes.**

## v2.1.0 — The New Era Edition

**Glass-box tools: every Grok tool now says what it does — reads, writes or rewrites — so your client knows when to ask first. New card, new look at grok.faf.one.**

- **Every tool is labelled.** All 20 tools carry MCP tool annotations, checked against what each handler really does: 7 read only, 3 can delete or overwrite (`faf_init` with `force`, `faf_clear`, `faf_write`), the rest write without losing anything. Only `rag_query` reaches the network (xAI Collections).
- **Honest about receipts.** `refresh_faf`, `refresh_fafm`, `refresh_blend`, `faf_orchestrate_recommendation` and the FRC tools (`faf_gate`, `faf_section`, `faf_memory`) append small receipt files to your project folder, so they are labelled as writers. `refresh_fafm` no longer says "Read-only".
- **Its own card.** Grok FAF now has a FAF passport (`agent.fafa`) at [grok.faf.one/.well-known/fafa](https://grok.faf.one/.well-known/fafa), with AI Catalog and ARD entries that point to it. The MCP Server Card is the hosted one, also at `grok.faf.one/.well-known/mcp/server-card.json`.
- **A new look.** [grok.faf.one](https://grok.faf.one) is redesigned, with the current facts: 19 tools hosted, 12 by default locally.
- **Node 22 or later**, like faf-cli 8 and the rest of the FAF family.

> Earlier: v2.0.0 — **The Always33 Edition** — one engine, one number: every score is faf-cli 8's always-33 kernel, on npm and on mcpaas.live. ZEPH is opt-in until the Zig engine is always-33.

☆ Bookmark [grok.faf.one](https://grok.faf.one) for later.

**First v0.2-conformant reader** of the [FAF Context Ingestion Contract](https://github.com/Wolfe-Jam/faf/blob/main/CONTEXT-INGESTION.md) — the open standard co-authored in public with @grok.

## Install — one line

Add to `~/.grok/config.toml`:

```toml
[mcp_servers.grok-faf-mcp]
url = "https://mcpaas.live/grok/mcp/v1"
```

Restart Grok TUI (or `/mcps r`) to refresh. The hosted endpoint scores always-33 — the same number as the npm package. Tools: `faf_score`, `faf_validate`, `faf_get_tier`, `faf_estimate_tokens`, `faf_analyze` (plus soul/memory ops).

**Smithery:** [wolfe-jam/grok-faf-mcp](https://smithery.ai/servers/wolfe-jam/grok-faf-mcp) — gateway at `https://grok-faf-mcp--wolfe-jam.run.tools`

**Homebrew (local stdio):**

```bash
brew install wolfe-jam/faf/grok-faf-mcp
```

**Hosted on Cloudflare Workers** — sub-ms cold start, no subprocess, edge-served. Scores and validates with the faf-kernel WASM (always-33, the same engine as the npm package) since mcpaas-cf 1.8.1; a Zig WASM engine handles token estimates and tier. Externally validated by Grok S1 + S2 on 2026-05-27.

**Verify the live contract:**

```bash
curl https://mcpaas.live/grok/mcp/v1/info
```

Returns endpoint, protocol versions, engine details, tool list, and the architecture line: `.faf=vROM | AI-in-session=RAM`.

Sample corpus: [`xai-faf-proof/pilot`](https://github.com/Wolfe-Jam/xai-faf-proof/tree/main/pilot) — 10 records ready to score.

## The 6 Ws - Quick Reference

Every README should answer these questions. Here's ours:

| Question | Answer |
|----------|--------|
| **WHO** is this for? | Grok/xAI developers and teams building with URL-based MCP |
| **WHAT** is it? | Persistent project context for xAI Grok — URL-first deployment, IANA-registered .faf format |
| **WHERE** does it work? | Cloudflare Workers (`mcpaas.live/grok/mcp/v1`) • Any MCP client supporting native `url=` config • Self-deploy to your own CF/Vercel worker |
| **WHY** do you need it? | Zero-config MCP on a URL — Grok asked for it, we built it first |
| **WHEN** should you use it? | Grok integration, xAI projects, any url-based MCP client |
| **HOW** does it work? | `url = "https://mcpaas.live/grok/mcp/v1"` — context tools served from edge via MCPaaS (sub-ms cold start, no subprocess) |

**For AI:** Read the detailed sections below for full context.
**For humans:** Use this pattern in YOUR README. Answer these 6 questions clearly.

### For the xAI / Grok Build team

Built **for** Grok and shaped by direct Grok feedback.  
Open for native Grok Build integration, .fafm memory layer, refresh_faf primitives, or any other context features the team needs.  
Live and dogfooded at https://grok.faf.one and https://mcpaas.live/grok/mcp/v1.

**Context for Grok agents:** faf-cli authors what Grok agents read from real project detection — `bunx faf export --agents`. faf-cli's `src/interop/grok.ts` wires this MCP into `.grok/config.toml` (that file lives in the faf-cli repo, not here). See [FAF-CLI for Grok & xAI agents](https://github.com/Wolfe-Jam/faf-cli/blob/main/docs/faf-cli-for-agents.md).

---

## The Problem

Every Grok session starts from zero. You re-explain your stack, your goals, your architecture. Every time.

`.faf` fixes that. One file, your project DNA, persistent across every session.

```
Without .faf  →  "I'm building a REST API in Rust with Axum and PostgreSQL..."
With .faf     →  Grok already knows. Every session. Forever.
```

---

## One Command, Done Forever

`faf_auto` detects your project, creates a `.faf`, and scores it — in one shot:

```
faf_auto
━━━━━━━━━━━━━━━━━
Score: 0% → 85% (+85) ◇ BRONZE
Steps:
  1. Created project.faf
  2. Detected stack from package.json
  3. Synced CLAUDE.md

Path: /home/user/my-project
```

What it produces:

```yaml
# project.faf — your project, machine-readable
faf_version: "3.3"
project:
  name: my-api
  goal: REST API for user management
  main_language: TypeScript
stack:
  backend: Express
  database: PostgreSQL
  testing: Jest
  runtime: Node.js
human_context:
  who: Backend developers
  what: User CRUD with auth
  why: Replace legacy PHP service
```

Every AI agent reads this once and knows exactly what you're building.

## Scoring: From Blind to Optimized

| Tier | Score | What it means |
|------|-------|---------------|
| **🏆 TROPHY** | 100% | Gold Code — AI is optimized |
| **★ GOLD** | 99%+ | Near-perfect context |
| **◆ SILVER** | 95%+ | Excellent |
| **◇ BRONZE** | 85%+ | Strong baseline |
| **●** GREEN | 70%+ | Solid foundation |
| ● YELLOW | 55%+ | AI flipping coins |
| ○ RED | <55% | AI working blind |
| ♡ WHITE | 0% | Start — good luck |

At 55%, Grok guesses half the time. At 100%, Grok knows your project.

---

## Two Ways to Deploy

### 1. Hosted (zero install — recommended)
Point your MCP client at the production URL — edge-served on Cloudflare Workers, no subprocess, sub-ms cold start. WASM-pure tools only on this path (scoring, validation, `refresh_faf`).

```json
{
  "mcpServers": {
    "grok-faf": {
      "url": "https://mcpaas.live/grok/mcp/v1"
    }
  }
}
```

### 2. Local (stdio — for FS-touching workflows)
Use the local stdio path when you need filesystem access (`faf_init`, `faf_sync`, file-mutating tools):

```bash
brew install wolfe-jam/faf/grok-faf-mcp   # macOS tap
# or
bunx grok-faf-mcp
```

**Or via MCP config:**

```json
{
  "mcpServers": {
    "grok-faf": {
      "command": "bunx",
      "args": ["grok-faf-mcp"]
    }
  }
}
```

## MCP Tools

**Create & Detect**

| Tool | Purpose |
|------|---------|
| `faf_init` | Create project.faf from your project |
| `faf_auto` | Auto-detect stack and populate context |
| `faf_score` | AI-readiness score (0-100%) with breakdown |
| `faf_status` | Check current AI-readability |
| `refresh_faf` | Re-ground on the live `.faf` — re-read + re-score, report drift, return fresh DNA (drift → refresh → re-grounded). **Requested by Grok.** |

**Drift & Orchestration (1.5 — the prestige release)**

| Tool | Purpose |
|------|---------|
| `refresh_fafm` | Re-ground on the live `.fafm` memory layer for one or more souls. Returns a stamped delta (added/updated facts) by default; `verbatim: true` for full content. Read-only · always stamped. Sister to `refresh_faf` for the RAM/memory layer in the vROM/RAM model. **Built for Grok, by request.** |
| `refresh_blend` | The baked-in two-intensity refresh (Cmd+R / Cmd+Shift+R analog). `mode: "blend"` (default) fires `refresh_faf` (light) + `refresh_fafm` (delta); `mode: "nuke"` fires both at hard intensity. Blend is **BAKED IN, NOT a dial** — both layers always fire; mode only affects fafm intensity. |
| `faf_orchestrate_recommendation` | The heavy orchestrator. Reads current substrate state, composes the full 1.5 library substrate (drift detection · CheckID · repeat-offender · take-a-hint · refresh history), returns a structured `Recommendation` with `recommend`, `severity`, `summary`, `reason`, and a rich `hints` object including `effective_policy` (the tier in force). **Advisory only — never auto-fires** (subordinate-not-daemon). Writes a recommendation receipt on every call (no silent decisions). Spec source: Grok-1 `FAF-DRIFT-DETECTION-SPEC §9.5 + Appendix C`. |
| `faf_get_orchestration_policy` | Pure introspection of the effective policy WITHOUT running the orchestrator. Returns `{ tier, thresholds, source, overrides_applied }` — what aggressiveness tier the next orchestration call would use, and whether it came from defaults or a `.faf:orchestration:` override. No drift detection · no signals · no receipt write — the quietest tool in the 1.5 substrate. Useful for debugging unexpected orchestrator behavior, pre-flight checks before bulk operations, and override-took-effect verification. |

**Sync & Persist**

| Tool | Purpose |
|------|---------|
| `faf_sync` | Sync .faf → CLAUDE.md |
| `faf_bi_sync` | Bi-directional .faf ↔ platform context |
| `faf_trust` | Validate .faf integrity |

**Read & Write**

| Tool | Purpose |
|------|---------|
| `faf_read` | Read any file |
| `faf_write` | Write any file |
| `faf_list` | Discover projects with .faf files |

**RAG & Grok-Exclusive**

| Tool | Purpose |
|------|---------|
| `rag_query` | RAG-powered context retrieval |
| `rag_cache_stats` | RAG cache statistics |
| `rag_cache_clear` | Clear RAG cache |
| `grok_go_fast_af` | Auto-load .faf context for Grok |

Plus 34 advanced tools available with `FAF_SHOW_ADVANCED=true`.

## Performance

```
Execution:    0.5ms average (97% faster than v1.1)
Fastest:      3,360ns (version — nanosecond territory)
Slowest:      1.3ms (score — Mk4 WASM)
Improvement:  19ms → 0.5ms (3,800% faster)
Engine:       faf-cli 8 (faf-scoring-kernel 3.0.0, always-33)
Memory:       Zero leaks
Transport:    stdio (local, bunx) · Streamable HTTP (hosted, Cloudflare Workers)
```

Benchmarked 10x per tool, warmed up, on local stdio execution. Hosted edge adds sub-ms cold start on top.

**Orchestrator (`faf_orchestrate_recommendation`) characteristics:** composition call — reads up to 6 files (`.faf`, `.fafm`, `package.json`, `CHANGELOG.md`, `README.md`, plus all 3 receipt logs), runs 2 analyzers (`detectFafmDrift` + `checkId`), evaluates the decision table, writes 1 receipt. Expected latency: tens of ms on warm cache; higher under cold-disk or very large `.fafm` corpora. **Designed for occasional agent-initiated calls, not per-turn polling.** `detectFafmDrift` is O(n²) in fact count (cross-fact n-gram recurrence) — comfortable up to ~hundreds of facts.

```

**Production deployment:** Cloudflare Workers via `mcpaas-cf` (serving `mcpaas.live/grok/mcp/v1`). The `api/index.ts` + `vercel.json` paths above stay alive as a catch-site for legacy/bookmarked links — they are no longer the production path.

**Scoring pipeline:** faf-cli's `scoreFafYaml` → the always-33 kernel (`faf-scoring-kernel`, Rust → WASM) scores the file as written: 33 slots, `slotignored` slots drop out of the denominator. No per-type rewriting, no fallback scorer — the same number faf-cli, claude-faf-mcp and faf-mcp give.

---

## Testing

WJTTC parity (heavy local ↔ light hosted) + full suites (green on CI):

```bash
sh scripts/run-tests.sh
```

| Suite | Coverage |
|-------|----------|
| `desktop-native-validation` | Core native functions, security, performance |
| `mcp-conformance` | MCP protocol conformance — tools, transport, errors |
| `wjttc-mcp` | WJTTC MCP certification |
| `wjttc-bun` | WJTTC bun-migration + integrity |
| `rag-system` | RAG query, caching, context retrieval |
| `security` | Input validation + security guards |
| `visibility` | Tool visibility (core/advanced filtering) |

---

## Status & known limitations (v2.1)

v2.1.0 — **The New Era Edition** — glass-box tools (every tool labelled read, write or rewrite), its own FAF passport at grok.faf.one, a new look. Scoring is unchanged from v2.0.0.

v2.0.0 — **The Always33 Edition** — one engine, one number: faf-cli 8's always-33 kernel on npm and on mcpaas.live. ZEPH is opt-in until the Zig engine is always-33. FafCompiler upgraded to the Always33 fafb model — parity across frontier models, Enterprise/Teams ready.

Everything below still applies; operating it honestly means surfacing what's NOT in here alongside what is.

> Earlier: v1.10.0 — **The No-Fluff Edition** — no fluff in a project.faf. `faf_enhance` is gone. RAG default is `grok-4.6`. Fill stays on `faf_auto` / `faf_go`.

> Earlier: v1.9.0 — **The ZEPH Default Edition** — the proven-fast Zig→WASM scoring path behind `refresh_faf` is now **default-ON** (same score, cheaper to compute; parity proven byte-identical — CI gate + 91/91 live). Kill switch `USE_ZEPH=0` forces the canonical scorer. FRC tools stay opt-in behind `USE_FRC`.

> Earlier: v1.8.0 — **The Closed-Loop Edition** — observability writes, token math is honest, FRC contract locked. The drift→refresh→re-ground loop can finally be measured.
> Earlier: v1.7.0 — **The Grounded Memory Edition** — ZEPH + the FRC layer over Grok Collections (`faf_gate`/`faf_section`/`faf_memory`), opt-in via `USE_FRC`/`USE_ZEPH`; 12-tool core unchanged.
> Earlier: v1.6.0 — **The ZEPH Edition** — the ZEPH fast path for re-grounding (`refresh_faf`/`refresh_blend` via Zig→WASM `cascade.wasm`, ~12µs, `USE_ZEPH=1`; `faf-cli` stays canonical, parity locked in CI).

**What is fully supported:**
- 19 tools on the hosted endpoint (`https://mcpaas.live/grok/mcp/v1` and client-specific routes) — scoring · validation · `refresh_faf` · a content-in `faf_orchestrate_recommendation` · the FRC trio · souls and search. The live list is at `…/grok/mcp/v1/info`.
- `refresh_faf` and `refresh_fafm` as explicit, callable re-grounding primitives.
- `refresh_blend` as the baked-in two-intensity refresh (Cmd+R / Cmd+Shift+R analog).
- `faf_orchestrate_recommendation` — the heavy orchestrator that composes drift signals, recurrence, receipts, and take-a-hint into an advisory recommendation.
- `faf_get_orchestration_policy` — pure introspection of the effective policy without running the orchestrator (no drift detection, no receipt write — the quietest tool in the substrate).
- Full policy visibility (`effective_policy`) returned on every orchestration call AND surfaced standalone via `faf_get_orchestration_policy`.

**Current limitations:**

- **`faf_get_orchestration_policy`, `refresh_fafm`, `refresh_blend`, `faf_init` and `faf_sync` need filesystem access** and run only on the local stdio path (`bunx grok-faf-mcp` / `npx grok-faf-mcp`). The hosted `faf_orchestrate_recommendation` takes file contents instead of reading your repo, and has no receipts or recurrence history (it reports those under `partial[]`).
- **Receipt storage — cwd-relative JSON, pull-discoverable.** Three append-only JSON files live at the repo root with stable schemas:
  ```
  .faf-drift-index.json              ← RepeatOffenderTracker — per-slot recurrence counts
  .faf-refresh-receipts.json         ← RefreshReceiptsLog    — every refresh fire
  .faf-recommendation-receipts.json  ← RecommendationReceiptsLog — every orchestrator call
  ```
  **Pull-discoverable by external tools** (TAF, custom indexers, observability dashboards) — read on your own schedule, no callback/push API required. Promotion to a dedicated orphan branch (mirroring the TAF pattern) is documented but deferred per ship discipline; the cwd-relative JSON is the v1 bootstrap.
- **No multi-process file lock** on the receipt logs. Within a process, the JS event loop serializes writes. Multi-agent concurrent writes can race; future task.
- **Aggressiveness tier hook** — `.faf:orchestration:tier` reads `'conservative'` (default — quietest, no noisy first-impression) · `'balanced'` · `'aggressive'`. `active_tier` always surfaced in `hints.effective_policy` for observability, and standalone via `faf_get_orchestration_policy`. The policy WRITER (`faf_set_orchestration_policy`) and scheduling (`faf_schedule_heavy_re_ground`) are not included in v1.5 — edit `.faf:orchestration:tier:` directly to override.
- **No ack mechanism yet for recommendation receipts.** `acknowledged: false` by default, never auto-flipped. Take-a-hint's ladder-reset semantics fire only on explicit ack — conservative by intent. Future task: explicit `ack` tool OR derived-from-subsequent-refresh-receipt timing.
- **Outcome tracking** (*"did this recommendation actually help?"*) — needs a learning layer beyond 1.5 scope.

**The honest split is intentional:** hosted = fast, auditable, WASM-pure; local = full capability including filesystem. We will expand the hosted surface only where it can be done safely and without compromising the model.

**Subordinate-not-daemon throughout.** The orchestrator NEVER auto-fires the recommended tool. Agents surface the recommendation; the user (or higher agent) decides whether to act. Even `severity: 'block'` is advisory.

See the [public verifier](https://grok.faf.one/) and `curl https://mcpaas.live/grok/mcp/v1/info` for the current contract.

## Voice variant — `grok-faf-voice` (VML)

`.fafm 🐘🎙️` — the voice variant of the `.faf 🐘` family.

**[grok-faf-voice](https://pypi.org/project/grok-faf-voice/)** is the reference implementation of the **Voice Memory Layer (VML)** — what your voice agent *remembers* across sessions, devices, and model switches. Companion to `grok-faf-mcp`:

- **`grok-faf-mcp`** (this) — `.faf` Foundational Context Layer for Grok via MCP-on-a-URL.
- **`grok-faf-voice`** — `.fafm` Voice Memory Layer (VML) for Grok Voice via LiveKit + xAI realtime.

Same family. Different surface. *Voice swappable; memory permanent.*
