Rust Faf Mcp
Expose the IANA-registered .faf format and eight Rust-native RMCP tools so your coding agent can read and write interoperable agent artifact files without custom parsers.
Overview
rust-faf-mcp is a MCP server for the Build phase that exposes eight tools for working with the IANA-registered .faf format via a Rust-native RMCP server.
What is this MCP server?
- Eight MCP tools backed by a Rust-native RMCP FAF server
- IANA-registered .faf format for standardized agent artifacts
- stdio transport with an mcpb binary package for darwin-arm64
- Published server schema v0.2.2 aligned with MCP registry conventions
- Documented at faf.one with GitHub source at Wolfe-Jam/rust-faf-mcp
- 8 MCP tools exposed by the FAF server
- Server version 0.2.2 in registry metadata
- Transport: stdio via mcpb package
Community signal: 3 GitHub stars.
What problem does it solve?
Agent projects stall when every tool invents its own artifact format and nothing in the IDE can read or validate those files consistently.
Who is it for?
Indie builders standardizing agent interchange files and wiring Claude Code or Cursor to a spec-backed FAF toolchain.
Skip if: Teams that only need generic file I/O or who are not adopting the .faf format on faf.one.
What do I get? / Deliverables
After you register the stdio server, your agent can create, inspect, and manipulate .faf artifacts through MCP instead of one-off shell scripts.
- Registered stdio MCP connection to the FAF tool suite
- Agent-callable operations on .faf-format resources
- Repeatable artifact handling aligned with faf.one documentation
Recommended MCP Servers
Journey fit
FAF is an agent-facing file format and tool surface, so the natural home in the solo-builder journey is when you are wiring agent tooling and shared artifacts into the product. Agent-tooling is where MCP servers that define or manipulate agent-specific formats belong, ahead of broader backend or frontend feature work.
How it compares
MCP format server with eight tools, not a Claude skill markdown workflow or a hosted SaaS dashboard.
Common Questions / FAQ
Who is rust-faf-mcp for?
It is for solo developers and small teams building agent-centric products who want MCP-accessible operations on IANA-registered .faf files from a Rust RMCP implementation.
When should I use rust-faf-mcp?
Use it during the build phase while you define agent artifacts, plugins, or shared bundles that should conform to the FAF specification rather than private JSON schemas.
How do I add rust-faf-mcp to my agent?
Add the mcpb stdio package from the MCP registry entry (rust-faf-mcp-darwin-arm64.mcpb for Apple Silicon) in Claude Code, Cursor, or another MCP client that supports mcpb, then point tools at the server name io.github.Wolfe-Jam/rust-faf-mcp.
