How we score
What the number actually means
Every server gets a 0–100 grade from five weighted signals. No opinion — only what we can measure from source, registry, and runtime.

Frequently asked questions
What is an MCP server?+
An MCP (Model Context Protocol) server is a small program that exposes tools, data, or actions to AI assistants like Claude Desktop, Claude Code, Cursor, and Windsurf. Servers can read files, query databases, call APIs, search the web, or trigger workflows — the AI agent calls them just like a function.
How does MCPpedia score MCP servers?+
Every server gets a 0–100 score across five axes: Security (CVE scanning, tool-poisoning detection, auth requirements, license), Maintenance (commit recency, GitHub stars, open issues, weekly downloads), Documentation (README quality, setup steps, examples, schema coverage), Compatibility (transports and confirmed clients), and Efficiency (total tool tokens, tokens per call). Methodology is fully public.
Which MCP server should I install first?+
Start with the use-case tile that matches your work: developers usually want filesystem, GitHub, and a database server (Postgres or Supabase); productivity users want Slack, Notion, or Google Drive; AI-agent builders want web-search and memory servers. Filter by score, then check CVEs and last-commit recency before installing.
Is MCPpedia free? Who runs it?+
MCPpedia is free, has no paywall, and accepts community submissions. It tracks 34,442+ servers, scoring each one independently. Listings are not pay-to-play; vendors can claim and verify their servers but cannot pay for ranking.
