SkillsIndex MCP

Search, score, and submit AI agent tools from SkillsIndex

What this skill does

Gives your AI agent read/write access to the SkillsIndex public directory — 11,000+ MCP servers, Claude skills, GPT actions, and IDE plugins, each scored on security, utility, maintenance, and uniqueness.

Security & transparency

• No credentials required — no API keys, no GitHub tokens, no secrets
• No local file access — the skill makes no filesystem operations
• Network calls only — all calls go to skillsindex.dev (public REST API over HTTPS) and npmjs.com (for npx to download the package)
• Read-only by default — search, get_tool, get_top_rated, check_security are all read-only
• Write operations — submit_tool POSTs a tool name + URL to skillsindex.dev/api/mcp/submit (public endpoint, no auth); subscribe POSTs an email to skillsindex.dev/api/subscribe
• Open source — full source code at https://github.com/thomasblc/skillsindex in the mcp/ directory
• No data exfiltration — the skill never reads or transmits your local files, environment variables, or system data

How it works

The skill runs as a local stdio MCP server via npx skillsindex-mcp. It bundles the compiled TypeScript and calls the SkillsIndex public API endpoints. No server is installed permanently — npx runs the package on demand.

Exact network endpoints called:

Tool	Endpoint	Method
search_tools	https://skillsindex.dev (Supabase REST API, anon key)	GET
get_tool	https://skillsindex.dev (Supabase REST API, anon key)	GET
get_top_rated	https://skillsindex.dev (Supabase REST API, anon key)	GET
check_security	https://skillsindex.dev (Supabase REST API, anon key)	GET
submit_tool	https://skillsindex.dev/api/mcp/submit	POST
subscribe	https://skillsindex.dev/api/subscribe	POST

The Supabase anon key is a public read-only key — it only allows reading published tool data. This is the same key embedded in every SkillsIndex web page.
