## Tools (as reported by the server, not verified)

- `trust\_score`: When to call: before you connect to, install, wire into an agent, or recommend an MCP server, to check what the public record shows about whether it is still maintained. Pass the MCP schema-server id. Returns: JSON with trust\_score \(0 to 100 or null\), display \(score · depth · provisional\), depth/dep
- `schema\_history`: When to call: before you rely on an MCP server's tools being stable, e.g. you are about to integrate it, pin tool names, or check whether the tool list changed under the same server id. Returns: dated facts, not a score: first\_seen, last\_observed, drift\_events, n, and observations\[\] with observation
- `dependency\_risk`: When to call: before you connect to or recommend an MCP server, when you care whether its declared dependencies were observed dead or dormant in the lastseen.dev register. Returns: dated facts, not a score: depends\_on\[\], dead\_dependency\_count, dormant\_dependency\_count, n, provenance. Empty depends\_o
