x-guidance: 'Annalist sells signed data for agents, priced per call over x402 (USDC on Base or Solana). Start with the free GET /v1/catalog: every paid route with the question it answers, its price and an example. Hyperliquid in one call: GET /v1/perp/full?coin=BTC (crowd state, smart-money positioning, liquidation levels). Before paying an x402 service: GET /v1/checks/service?host=, or the free GET /v1/verify/attestation?host=. Before connecting an MCP server: GET /v1/mcp/server?url=, or the free GET /v1/verify/mcp?url=. Before an agent shops on a site: the free GET /v1/verify/store?domain=, or GET /v1/web/readiness?domain=. Every answer is Ed25519-signed; the key is at /.well-known/annalist-key.json. Not investment advice.'

summary: Is this MCP server up and fast, does it need sign-in, and did its tools change?
description: 'Use before connecting a remote MCP server: independent checks by registry name or URL. Uptime and connect time from daily probes (initialize and tools/list; no tool is ever called), sign-in mode, protocol version, tool count, and tool-definition changes in 30 days (how ''rug pull'' attacks work), with domain age, a grade and reasons. Covers remote servers in the Official MCP Registry. Signed.'

description: 'Leaderboards from our independent checks of remote MCP servers in the Official MCP Registry: most reliable (up in 99%+ of probes, fastest first), servers whose tool definitions changed in the last 7 days, flagged servers (often down, new domains), and counts by sign-in mode, with the method. Rankings are never for sale. Signed.'

summary: Which MCP servers changed their tools recently, and what exactly changed?
description: 'Tool changes across remote MCP servers in the Official MCP Registry, newest first: tools added, removed or redefined (description, input schema or annotations), from our daily fingerprints. A tool that changes after you approved it is how ''rug pull'' attacks work, so check before trusting a server again. Last 1 to 30 days, or one server with name= or url=. Servers whose tools change by design are marked. Signed.'
