Gaia MCP

Agent-native discovery, trust, installation, and progression for the Gaia Skill Tree.

Status: the v0.1.0 Trusted Discovery implementation is under review. The npm package is not published yet; use the local development instructions below until the first release passes its publication gate.

Gaia MCP lets an AI agent answer a practical question inside the user's current conversation:

Which evidence-backed skill fits this task, why should I trust it, and can you add it to this workspace safely?

It is a standalone Gaia Research instrument. It consumes canonical public data and validated local actions from Gaia Skill Tree; it does not own or mutate the Registry directly.

Repository roles

Related MCP server: aai-gateway

v0.1 tool surface

• gaia_search — find generic and Named Skills by task and constraints.

• gaia_inspect — return an evidence-backed skill dossier.

• gaia_status — report server compatibility, Registry freshness, counts, and source URLs.

The first three tools are implemented in read-only Registry mode for v0.1.0. gaia_analyze_project and gaia_plan_path arrive with Bonded mode in v0.2.0.

Installation, updates, and Intake submission arrive only after the read-only surface is trustworthy. Every action will route through the canonical Gaia CLI and require explicit approval where it changes the workspace or external state.

Run the development server

Requires Node.js 22.14 or newer.

npm ci
npm run build
node dist/bin/gaia-mcp.js

The server speaks MCP over stdio, so it normally appears idle when run directly. Connect it from an MCP client using the absolute path to dist/bin/gaia-mcp.js.

After v0.1.0 is published and its clean-install gate passes, the canonical Claude Code installation will be version-pinned:

claude mcp add gaia -- npx -y @gaia-research/mcp@0.1.0

Do not use that npm command until the package appears in the Gaia MCP releases.

The public projection endpoints can be overridden for testing with GAIA_REGISTRY_URL and GAIA_NAMED_SKILLS_URL.

Verify

npm run check       # typecheck, unit/protocol tests, build
npm run test:live   # current gaiaskilltree.com data contract
npm pack --dry-run  # publishable artifact contents

Non-goals

Gaia MCP is not:

• a conversational wrapper around every gaia command;

• a second Registry implementation;

• the engine that creatively fuses SKILL.md files;

• a direct Registry or Skill Tree mutation path;

• a background update daemon;

• part of the Gaia Research website runtime.
