MCP tool search · surface index

The official registry publishes server names, not tool lists. This playground searches the daily measured surface and change feed. Idle $0; no-key demo quota.

The review score is a heuristic, not a verdict; evidence is in riskFlags. Not legal advice or a trust certificate for a server.

Pick Search tools or Changes. Example: search invoice · or description changes in the last 30 days.

Which endpoint?

GET/POST /v1/mcp/index — view=search | changes | server | tool | stats. Measurement: initialize + tools/list only.

Is this the official MCP registry?

No. The official registry publishes name/address, not tool surface. This index calls tools/list daily and stores it. Search, history and rug-pull detection come from that archive.

Free vs paid?

The playground is an anon IP demo quota. A paid API key is for software integration, filtering, history and metering. Idle $0. The public alert JSON (/mcp/changes.json) stays keyless.
