Tools (4)

create_bin

Create a new no-signup capture bin. Returns a live URL you can point any webhook, callback, or agent tool-callback at, plus a token to read what it captured. No account needed.

get_requests

Read the HTTP requests captured by a bin (method, path, query, headers, body), newest first. Set wait to block until a request arrives — ideal for 'trigger then assert' with no polling loop.

set_response

Configure the HTTP response a bin returns to whatever hits its URL — set a status code, content-type and body. Use it to test how your webhook sender / agent handles a 500, a specific JSON reply, etc. Omit or reset to return the default 200. Requires the bin token.

clear_bin

Delete all captured requests from a bin (the bin stays usable). Requires the bin token.

How we measure →

What this means. This server responded to the MCP handshake and listed its tools without authentication. The schema fingerprint lets us flag if tool signatures silently change (schema drift) between checks.
