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 92 of 92 checks got a reply (100.0%), average response time 63 ms. The bar chart above shows every period we have measured.
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.
How fast is Catchr?
It answers our handshake in 63 ms on average, which is faster than 95% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
