Is lastseen-score live?

Yes — it answered the hub's last check (checked 2h ago). It answered 99% of checks over the last 30 days.

Is lastseen-score free to use?

Not measured yet.

What tools does lastseen-score have?

3 tools: trust_score, schema_history, dependency_risk.

Is lastseen-score safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• trust_score reads unknown never probed

  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/depth_max, per-dimension values (liveness, maintenance, adoption, spec_currency, dependency_health; null = unknown, never invented), effective_weights, resolution method/confidence, status (scored | unresolved | insufficient_data), methodology URL. Depth 2 answers mortality more than merit; cite display as-is. Not a prediction, not advice, not a ranking of alternatives. Example: {"id":"io.github.06ketan/medium-ops"} id: MCP schema-server identifier (e.g. io.github.owner/name or owner/name). Not an npm package name, Action slug, or Docker image.

• schema_history reads unknown never probed

  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_date, tools_hash, tool_count (may be null), changed. Use trust_score for the derived score and dependency_risk for dependency mortality counts. Example: {"id":"io.github.06ketan/medium-ops"} id: MCP schema-server identifier (e.g. io.github.owner/name). Same id space as trust_score.

• dependency_risk reads unknown never probed

  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_on or zero counts means no dependency edges were on record for that id as of the response, not a guarantee of zero risk. Example: {"id":"io.github.06ketan/medium-ops"} id: MCP schema-server identifier whose dependency edges to inspect (e.g. io.github.owner/name).
