Headroom
Compress tool outputs, logs, files, and RAG chunks before they reach the LLM. 60-95% fewer tokens, same answers. Library, proxy, MCP server.
MCP servers that span multiple categories or serve specialized use cases — all security-scored.
MCPpedia tracks 8,943 other MCP servers. 1,102 of them score at least 50 out of 100, and 202 clear 70 — about 2% of what has been published in this space. The remaining 7,841 are thinner: registry entries with no description, no published tool schema, or no commit in the last year. They are all still listed here, because knowing a server exists and is unmaintained is worth as much as knowing a good one exists.
Headroom leads the list at 95/100. Pi Lean Ctx (95) and Brigade (93) follow. Every score is the same five weighted inputs: security (CVE scanning, tool-poisoning detection, and whether the server authenticates at all), maintenance (commit recency, release cadence, and download trend), documentation, client compatibility, and token efficiency — how much of your context window the tool definitions consume before you have asked anything.
1 of these servers are published by the vendor behind the underlying API rather than by a third party, which is usually the difference between an integration that tracks upstream changes and one that quietly stops working. 6 currently carry an open CVE; those are flagged on the server's own page with the advisory and its severity.
