skill-router-mcp

Remote MCP server exposing the 501-skill "Claude Skills Ultimate Bundle" as two tools:

• search_skills(query, limit?) — keyword-scored search over all 501 name/category/description entries
• get_skill(name) — returns the full SKILL.md content for one match

No manual per-skill upload, no 20-skill cap. Claude calls these tools itself when a task looks like it needs one of the bundled skills.

Structure (8 files total — small enough to upload via the GitHub website)

• src/index.js — the Worker / MCP server (Cloudflare Agents SDK, createMcpHandler)
• public/index.json — metadata index (name, category, description) for all 501 skills — used for search
• public/skills-content.json — one JSON object, keyed by skill name, containing the full SKILL.md text for all 501 skills — used by get_skill. Consolidated into a single file on purpose so the whole repo stays under GitHub's 100-file web upload limit.
• scripts/build-index.cjs — regenerates both public/*.json files from a source bundle folder. Only needed again if skills are added or changed.

Rebuilding the index (only needed if skills are added/changed)

node scripts/build-index.cjs "<path to Claude Skills Ultimate Bundle folder>" ./public

Deploying

See the setup instructions provided alongside this file — deployment is done entirely through the GitHub website and the Cloudflare dashboard (Workers Builds / Connect to Git), no terminal required beyond unzipping this folder locally.

Optional auth

Add an AUTH_TOKEN secret in the Cloudflare dashboard (Workers & Pages > your Worker > Settings > Variables and Secrets) to require Authorization: Bearer <token> on every request. If no secret is set, the server is open to anyone with the URL.
