Pulled straight from the server with tools/list on 2026-10-17.
list_tunnelsread-only

List the user's Pipehero tunnels and whether each is currently online.

list_requestsread-only

List recent webhooks/requests captured for a tunnel. Returns id, method, path, status and bodies.

get_requestread-only

Get the full request and response (headers + body) of one captured webhook by id.

replay_requestcan modify

Replay a captured webhook to the user's localhost (the tunnel CLI must be running).

send_test_webhookcan modify

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.

set_long_requests

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

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.

list_api_collectionsread-only

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

get_api_collectionread-only

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

get_api_endpointread-only

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.

create_api_collection

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.

upsert_api_endpoint

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.

add_api_example

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.

delete_api_endpointcan modify

Delete an endpoint and its examples. Use when the route no longer exists in the code. Cannot be undone.

import_api_spec

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.

export_api_collectionread-only

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

run_api_endpointcan modify

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

save_captured_request

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

list_api_monitorsread-only

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_proposalsread-only

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.

check_api_driftread-only

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 t

get_api_share_linkread-only

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).

share_api_endpoint

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 ema

share_api_collection

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

list_api_runsread-only

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.
