Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

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

Catchr — questions

Answers built from our own checks of this server.

What can Catchr do?
It exposes 4 tools, read directly from the server on our last check. Among them: clear_bin, create_bin, get_requests, set_response. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Catchr working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 77 ms. The bar chart above shows every period we have measured.
The registry lists Catchr as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Catchr?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Catchr need an API key?
No. Catchr completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
