Queries the European Patent Office Linked Open Data endpoint, which is the only patent source still reachable without a key: PatentsView has been retired, and both EPO OPS and the USPTO Open Data Portal answer 403 without credentials. Coverage is therefore EP publications and this is stated in every response, because an empty result here proves only that no European publication exists, not that no patent does.

Detect when an Apify Actor, API, scraper or data feed breaks, goes stale or silently changes shape. One paid call returns a verdict with the evidence behind it, so an agent can decide whether a data source is still trustworthy before acting on it. Works with any HTTP endpoint; 35+ pre-wired vendors (OpenAI, Anthropic, Stripe, GitHub) are a head start, not a limit. Schedule it on your own cadence for continuous monitoring of breakage, staleness and drift.

Performs the MCP handshake against a streamable-HTTP endpoint and then reads the catalogue: tools with their input schemas, resources with their URIs and mime types, and prompts with their arguments. Servers answering as an event stream are handled as well as plain JSON, and a session id is carried across calls. Only listing methods are sent — no tool of the inspected server is ever executed, nothing is written, and no resource contents are read.
