MCP Inspector

Run the official MCP Inspector locally and enter the indexed Streamable HTTP endpoint.

get_entry — One entry's full record: metadata, license, verification state, and the Access Contract — a ranked list of actionable URLs (direct downloads, verified runnable requests, specs).
related_entries — An entry's graph neighborhood: containment relations (portal ⊃ dataset, service → dataset), same-publisher siblings, and the join-key identifiers its fields carry (with fan-out counts).
find_joinable_sources — Every register source whose data carries a given join-key identifier (e.g.
plan_query — PLAN a query WITHOUT running it: which source it would hit, the exact upstream request, how many requests, roughly how long (from that source's own measured latency, or null when nothing has been measured — never a guess), which fields would NOT resolve, and which filters cannot be pushed upstream and would be applied locally over a bounded window.
run_query — RUN a query against a live-tier source and get real rows back, with the exact upstream request used.
cite_query — CITE a query: run it and persist an immutable evidence manifest (query spec, upstream request, retrieval time, result hash, license).
subscribe_to_changes — SUBSCRIBE to a source: returns its change-feed URL (RSS, no account needed) plus the recent change events — verification failures, schema changes, deprecation.
