```


## Deletes or cancels (4)

Removes, cancels or revokes something. Claude Code: deny.

### `delete_api_endpoint`

- The name "delete_api_endpoint" says "delete": a word for removing or ending something.
- The description says "Cannot be undone".
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Delete an endpoint and its examples. Use when the route no longer exists in the code. Cannot be undone.
```

### `replay_request`

- The name "replay_request" says "request": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Replay a captured webhook to the user's localhost (the tunnel CLI must be running).
```

### `run_api_endpoint`

- The name "run_api_endpoint" says "run": a word for a change.
- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Send an endpoint against an environment and return the real response (status, headers, body up to 20 KB). A `local` environment goes through the user's tunnel to their localhost (the CLI must be running); staging/prod are sent from Pipehero's cloud (Pro/Team) to public addresses only. Sending to a `prod` environment with a write method needs confirm_write_to_prod: true, which you should only pass after the user agrees. Use it to check that the code you wrote behaves as documented.
```

### `send_test_webhook`

- The name "send_test_webhook" says "send": a word for sending, and what is sent cannot be taken back.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Send a generated test webhook to the user's localhost (the tunnel CLI must be running). Provide a `provider` (stripe, github, shopify, clerk, slack, resend, paddle, polar, lemonsqueezy) and optional `event` for a realistic sample payload, or pass a custom JSON `body`. Pro plan required.
```

## Changes things (10)

Creates or changes something that can be changed back. Claude Code: ask.

### `add_api_example`

- The name "add_api_example" says "add": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Save a response example on an endpoint (for instance the 402 your handler returns for a declined card). Replaces the example with the same name, so it is safe to repeat.
```

### `create_api_collection`

- The name "create_api_collection" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create an empty API collection. Prefer import_api_spec when there is an OpenAPI file, and upsert_api_endpoint to fill it from the code.
```

### `export_api_collection`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Export a collection as an OpenAPI 3.1 or Postman 2.1 document. Handy to read the whole API at once.
```

### `import_api_spec`

- The name "import_api_spec" says "import": a word for a change.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Import an OpenAPI 3.x document (as JSON), a Postman v2.x collection (JSON) or a curl command into a new collection, or into `collection_id`. All or nothing, and plan limits are checked first. Credentials are never imported (they become variables). Convert YAML to JSON before sending.
```

### `save_captured_request`

- The name "save_captured_request" says "save": a word for a change.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Document a real request captured by a tunnel (get its id from list_requests). If an endpoint already covers the route, the response is added to it as an example; otherwise an endpoint is created from the request. Credentials, cookies and signatures are replaced by {{variables}} and only JSON bodies are kept. A response already saved as an example is not duplicated. Use it to document webhooks and calls you have only seen in traffic.
```

### `set_long_requests`

- The name "set_long_requests" says "set": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Opt a tunnel into a 120-second ingress timeout instead of the 30-second default — for tool calls that legitimately run long, e.g. an MCP server exposed through the tunnel. Persists on the tunnel; pass enabled: false to revert to the 30-second default.
```

### `set_ws_passthrough`

- The name "set_ws_passthrough" says "set": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Opt a tunnel into WebSocket passthrough, so an application-level WebSocket connection (e.g. a mobile/web app's own realtime feature) can be relayed to your localhost. Pro/Team plan required to enable; pass enabled: false to disable on any plan.
```

### `share_api_collection`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Share a whole collection: every endpoint in it (including ones added later), with its examples and latest run, read-only and with secrets hidden. Environments are never shown and it can't be exported. Returns the collection's link, which never changes. With no other arguments it stays restricted to the workspace; set `link_access` or `invite` people only when the user asks to share it outside the team. get_api_collection returns the link as `share` once it exists.
```

### `share_api_endpoint`

- The description's first verb is "create": a word for a change.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Create an endpoint's shareable link and return it. With no other arguments the link stays restricted: workspace members can open it (they sign in), which is enough for a PR or an internal message. Only when the user asks to share it outside the workspace: set `link_access` to `viewer` (anyone with the link can read) or `commenter` (Team plan; commenting asks for sign-in), or `invite` people by email (they get an email and sign in with that address). `restricted` turns the public link off; the URL stays the same. The page is read-only and always hides credentials and secrets.
```

### `upsert_api_endpoint`

- The name "upsert_api_endpoint" says "upsert": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Document an endpoint: creates it, or updates the existing one for the same method + path. Use it whenever you add or change a route in the code, so the docs stay true. Only the fields you send change. `path` may use :id, {id} or {{id}} for variables. `folder` is created by name if missing. Send `version` (from get_api_endpoint) to avoid overwriting a teammate's edit; a stale version is rejected.
```

## Only reads (11)

Looks things up and changes nothing. Claude Code: allow.

### `check_api_drift`

- The description's first verb is "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Compare a collection's docs with the real traffic a tunnel captured (Pro/Team). Returns routes nobody documented, status codes with no example, response or request fields missing from every example (or with another type), undocumented query parameters, and documented fields that never appear. Each finding includes `request_id` of the newest request that shows it: pass it to save_captured_request to add it to the docs, or fix the docs with upsert_api_endpoint and add_api_example. Use it to find out what drifted after a code change.
```

### `get_api_collection`

- The name "get_api_collection" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get one collection's folders, endpoints (id, method, path, name, version, example count) and environments (with their variables).
```

### `get_api_endpoint`

- The name "get_api_endpoint" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get one endpoint in full: description, parameters, headers, request body, saved response examples and its current `version`. Identify it by endpoint_id or by method + path.
```

### `get_api_share_link`

- The name "get_api_share_link" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get the shareable link of an endpoint (a read-only page with its docs, examples and latest run, secrets hidden), who can open it and who was invited. Use it to put the link in a PR, an issue or a message. Each endpoint has one link that never changes; `shared: false` means it has none yet (see share_api_endpoint).
```

### `get_request`

- The name "get_request" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get the full request and response (headers + body) of one captured webhook by id.
```

### `list_api_collections`

- The name "list_api_collections" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the workspace's API collections (saved endpoints with examples and environments). Start here to find a collection_id.
```

### `list_api_monitors`

- The name "list_api_monitors" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
See which endpoints of a collection are checked on a schedule (Pro/Team monitors) and how they are doing: state (healthy, failing, blip, paused, waiting), the last check with its status, latency and error, and since when it has been failing. Use it to find out what is broken in staging or production, then read the endpoint and its code. Read-only: people decide what to monitor.
```

### `list_api_proposals`

- The name "list_api_proposals" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
See what happened to the changes you proposed. Some workspaces review AI changes: your write tools then answer `pending_review` and change nothing until a teammate approves. This lists the latest proposals with their status (pending, approved, rejected with the reviewer's reason, or failed with why) so you can tell whether a change went through.
```

### `list_api_runs`

- The name "list_api_runs" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Recent runs of an endpoint (newest first, default 5): who/what was sent and what came back. Use to see what happened the last time it was run.
```

### `list_requests`

- The name "list_requests" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List recent webhooks/requests captured for a tunnel. Returns id, method, path, status and bodies.
```

### `list_tunnels`

- The name "list_tunnels" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the user's Pipehero tunnels and whether each is currently online.
```
