How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security46
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not yet verified: we couldn't confirm whether this endpoint requires it. View diagnostics → Unverified
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 404, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability0
- Transport check failed: declared streamable-http, but the endpoint returned HTTP 404. See how to fix → View diagnostics → Fail
Schema Quality & AI Usability0
- Schema not yet verified: we couldn't read the endpoint's schema, or could read only part of its tool list.Unverified
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage0
- Tool coverage not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.Unverified
Tool Safety0
- Tool safety not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.Unverified
Capabilities0
- Capabilities not yet verified: we couldn't read the endpoint's capabilities.Unverified
Unverified: 5 categories
Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
clear_bin ~47
Delete all captured requests from a bin (the bin stays usable). Requires the bin token.
| Name | Type | Req | Description |
|---|---|---|---|
| bin_id | string | yes | The bin id. |
| token | string | yes | The bin token. |
No output schema declared.
No examples provided.
create_bin ~66
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.
| Name | Type | Req | Description |
|---|---|---|---|
| name | string | – | Optional label for the bin (max 60 chars). |
No output schema declared.
No examples provided.
get_requests ~152
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.
| Name | Type | Req | Description |
|---|---|---|---|
| bin_id | string | yes | The bin id returned by create_bin. |
| limit | integer | – | Max requests to return (default 20, max 100). |
| since | integer | – | Only return requests with ts greater than this (ms epoch). Use the ts of the last one you saw. |
| token | string | yes | The bin token returned by create_bin. |
| wait | integer | – | Seconds to block (max 25) until a request arrives. 0 = return immediately. |
No output schema declared.
No examples provided.
set_response ~146
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.
| Name | Type | Req | Description |
|---|---|---|---|
| bin_id | string | yes | The bin id. |
| body | string | – | Response body to return verbatim (max 16KB). |
| content_type | string | – | Content-Type header for the response (default application/json). |
| status | integer | – | HTTP status code to return (100-599). Default 200. |
| token | string | yes | The bin token. |
No output schema declared.
No examples provided.
How do I install the dev.workers.perch-app.catchr/catchr MCP server?
dev.workers.perch-app.catchr/catchr is a hosted endpoint at https://catchr.perch-app.workers.dev/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.
