The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
faf_about Faf About ~52
FAF format info — IANA registration, version, ecosystem. Returns metadata about the FAF format, server version, and available MCP bridges. Use this when users ask what FAF is or how it connects to other AI platforms.
Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.
No examples provided.
faf_agents Faf Agents ~118
Export and write AGENTS.md from a .faf file (non-destructive). Authors a BETTER-shaped AGENTS.md (setup · tests · layout · conventions · three-tier guardrails · definition of done · security · commit) via faf-python-sdk's authoring tool — in parity with faf-cli's `faf export --agents`. Injects it into AGENTS.md as a faf-managed block, preserving any hand content. Re-running updates the block in place — it never overwrites your file.
| Name | Type | Req | Description |
|---|---|---|---|
| path | string | – | – |
Structured output declared, but exposes no named fields.
No examples provided.
faf_auto Faf Auto ~144
Auto-detect project stack and author/update a .faf file. Scans package.json, pyproject.toml, Cargo.toml, go.mod, and other manifest files for language, framework, database, API type, and build tools — then grounds the result in the repo's own files: docker-compose service images (Postgres, Redis, Elasticsearch...) map onto stack slots, and Makefile / justfile targets map onto test / build / lint commands. Facts from files, no hardcoded defaults. Creates a new .faf if none exists, or fills empty slots in an existing one.
| Name | Type | Req | Description |
|---|---|---|---|
| directory | string | – | – |
| path | string | – | – |
Structured output declared, but exposes no named fields.
No examples provided.
faf_context Faf Context ~59
Get Gemini-optimized context from a .faf file. Returns the key sections an AI needs: project info, stack, instructions, and score. Use this to quickly understand a project without reading the full .faf structure.
| Name | Type | Req | Description |
|---|---|---|---|
| path | string | – | – |
Structured output declared, but exposes no named fields.
No examples provided.
faf_discover Faf Discover ~56
Find .faf files in the project tree by walking up from start_dir. Searches the current directory and parent directories for project.faf. Use this before faf_read to locate the file automatically.
| Name | Type | Req | Description |
|---|---|---|---|
| start_dir | string | – | – |
Structured output declared, but exposes no named fields.
No examples provided.
faf_gemini Faf Gemini ~112
Export and write GEMINI.md from a .faf file (non-destructive). Authors GEMINI.md in Gemini CLI's own convention (hierarchical, @file-importable — setup · verify · key files · stack · confirm-first actions) via faf-python-sdk's authoring tool, in parity with faf-cli's `faf export --gemini`. Injects it as a faf-managed block, preserving any hand content. Re-running updates the block in place.
| Name | Type | Req | Description |
|---|---|---|---|
| path | string | – | – |
Structured output declared, but exposes no named fields.
No examples provided.
faf_init Faf Init ~93
Create a starter .faf file with project name, goal, and language. Writes a valid FAF YAML file with all required sections. Will not overwrite an existing file — use faf_discover first to check. The path is confined to the project root (cwd / FAF_ALLOWED_ROOTS).
| Name | Type | Req | Description |
|---|---|---|---|
| goal | string | – | – |
| language | string | – | – |
| name | string | – | – |
| path | string | – | – |
Structured output declared, but exposes no named fields.
No examples provided.
faf_migrate Faf Migrate ~142
Migrate a .faf file to the current format version (3.0). Bumps `faf_version`, ensures the section roots exist (`project`, `stack`, `human_context`, `monorepo`), and re-serializes. Legacy slot names (`frontend`/`database`/…) still score via the registry's aliases — this only touches the version and structure, never your values. The file is re-serialized, so YAML comments and formatting are not kept. Parity with faf-cli's `faf migrate`. Pass dry_run=true to preview.
| Name | Type | Req | Description |
|---|---|---|---|
| dry_run | boolean | – | – |
| path | string | – | – |
Structured output declared, but exposes no named fields.
No examples provided.
faf_model Faf Model ~98
Get a 100% Trophy-scored example .faf file for a specific project type. Returns a complete, realistic project.faf that fills all 33 scored slots (populated, or slotignored where a slot does not apply). Use this as a reference when building or improving a .faf file — shows exactly what 100% looks like. Call without arguments to list all 15 available project types.
| Name | Type | Req | Description |
|---|---|---|---|
| project_type | string | – | – |
Structured output declared, but exposes no named fields.
No examples provided.
faf_read Faf Read ~55
Read project DNA from a .faf file. Returns the full parsed structure including project info, stack, preferences, and scoring data. Use this as the first step to understand any FAF-enabled project.
| Name | Type | Req | Description |
|---|---|---|---|
| path | string | – | – |
Structured output declared, but exposes no named fields.
No examples provided.
faf_score Faf Score ~68
Quick Mk4 score check — returns score (0-100%), tier, and slot counts. Uses the Mk4 always-33 scoring engine (faf-kernel parity) for universal parity. Use this for status checks; use faf_validate when you need error details.
| Name | Type | Req | Description |
|---|---|---|---|
| path | string | – | – |
Structured output declared, but exposes no named fields.
No examples provided.
faf_stringify Faf Stringify ~55
Convert parsed FAF data back to YAML string. Useful for displaying the raw .faf content or preparing it for editing. Reads the file, parses it, then re-serializes to clean YAML.
| Name | Type | Req | Description |
|---|---|---|---|
| path | string | – | – |
Structured output declared, but exposes no named fields.
No examples provided.
faf_validate Faf Validate ~61
Validate a .faf file and return score, tier, and issues. Returns errors (must fix) and warnings (should fix) with specific messages. Use after faf_init or when checking if a .faf file meets quality standards.
| Name | Type | Req | Description |
|---|---|---|---|
| path | string | – | – |
Structured output declared, but exposes no named fields.
No examples provided.

Is the Gemini FAF MCP server safe to use?
Gemini FAF scores 85 out of 100 on VerifyMCP. We recorded 10 known advisories against it as of 5 November 2026. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Gemini FAF MCP server expose?
Gemini FAF exposes 13 tools: faf_read, faf_validate, faf_score, faf_discover, faf_init, and 8 more. Their descriptions and schemas cost roughly 1,113 tokens of context every time the server is loaded.
Is the Gemini FAF MCP server still maintained?
Gemini FAF is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the Gemini FAF MCP server under?
Gemini FAF declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
