Server instructions

Toolpin reports observed facts about MCP servers in the public registry: whether a server answered when we last probed it, what its tools claimed to do, and whether that claim has changed. Every field comes with the time it was observed. Nothing here is a score, a rating, or a safety judgment, and no result should be read as one. Change counts arrive with the catalog base rate because drift concentrates in servers nobody depends on: compare a server against that rate before concluding anything about it.

Known tools 6

search_servers

Find MCP servers in the public registry by name or title.

Inferred read-only

get_server

Everything Toolpin has observed about one MCP server: reachability of each remote endpoint and when each was last checked and last verified, repository activity, the current tool-definition hash, and how many changes it has recorded in the last 90 days.

Inferred read-only

get_server_tools

The tool definitions one MCP server advertised when Toolpin last read them, each with a SHA-256 hash of the fields the MCP specification defines.

Inferred read-only

get_server_changes

Changes Toolpin recorded for one MCP server: tool definitions changing, and endpoints going down or coming back.

Inferred read-only

get_spec_status

The current MCP specification revision, which of its proposals Toolpin checks for, and how much of the catalog has migrated.

Inferred read-only

watch_server

Start monitoring an MCP server on the caller's Toolpin account, so they are emailed when it changes or stops answering.

Inferred read-only

Checking the associated registrable domain. The BuiltWith key remains server-side.

Indexed

Evidence is source-attributed and does not guarantee that a third-party server is safe. Risk labels are conservative metadata heuristics.
