Tools

• add_resource ~449 tokens
  Add a resource (collection) to a project and seed it with realistic fake data. Either pass template (one of the built-ins, e.g. users, products, posts, comments, orders, todos, reviews, customers, events) or fields: an array of {name, type} where type ∈ uuid|firstName|lastName|fullName|username|emai
• check_api_status ~300 tokens
  Live status of ~58 public mock/testing APIs — JSONPlaceholder, httpbin.org, ReqRes, FakeStoreAPI, DummyJSON, Postman Echo, httpstat.us, Mocky, Mockbin, CrudCrud, restcountries, and more — checked with a plain keyless GET every 30 minutes from Cloudflare's network (a service answering HTTP 200 error
• create_project ~517 tokens
  Create a new mock REST API project. Returns {id, adminKey, baseUrl, resources[]}. SAVE the adminKey — it is required for admin operations (add_resource, custom_route, snapshots) and is shown only once. Presets seed a full backend: blog (posts/comments/authors), ecommerce (products/orders/customers/r
• custom_route ~305 tokens
  Define a custom endpoint on a project (like /health, /config/:key, or a catch-all /webhooks/* request bin). body is a response template: {{query.x}} {{params.x}} {{body.x}} {{headers.x}} {{method}} {{path}} {{now}} {{ts}} {{uuid}} {{rand}}; triple braces {{{body}}} insert raw JSON. Custom routes tak
• delete_project Deletes data · ~138 tokens
  Permanently delete a project and ALL its data (records, resources, snapshots, custom routes, webhooks, request log). Irreversible. Good practice for short-lived test projects: clean up when your session is done. Requires the adminKey.
• fork_project ~386 tokens
  Copy an entire project — resources + records verbatim, custom routes, behavior settings — into a brand-new project with its own id + adminKey. Built for parallel eval/CI runs: keep a template project, fork_project per run with a ttl (crashed runs can't leak sandboxes — the fork deletes itself), let
• generate_fake_data ~529 tokens
  Generate realistic fake data instantly — stateless, nothing is created or stored, no project or adminKey needed. Ready-made resource shapes (FakerAPI-compatible): persons, users, addresses, companies, books, products, texts, images, places, credit_cards (credit cards are Luhn-valid; book EAN13/ISBN1
• heartbeat ~734 tokens
  Dead man's switch for cron jobs, scheduled tasks, and recurring agent runs — the INVERSE of uptime_monitor: the JOB pings Mockbird, and if the ping stops arriving the alert fires once (plus one recovery message when pings resume). action:"create" {name?, period_minutes, grace_minutes?, notify?}: per
• image_url ~894 tokens
  Mint a permanent, keyless image URL rendered by Mockbird — README badges (including LIVE record-count badges), chart images, QR codes, Open Graph cards, placeholder images, initials avatars. Deterministic: the same URL renders the same image forever (no account, no expiry, no watermark). Params are
• import_data ~405 tokens
  Create a live mock API from existing artifacts. Auto-detects: OpenAPI 3.x / Swagger 2.0 spec (JSON or YAML) → resources with realistic seeded data, and non-CRUD paths (login, /search, RPC verbs like POST /invoices/{id}/send) become custom routes serving the spec's own examples verbatim; json-server
• inspect_requests ~552 tokens
  Read the project's request inspector: the most recent requests that hit the mock API (method, path, query, status, origin, captured headers incl. x-* — authorization redacted to its scheme — and a body snippet for writes). Use it to VERIFY what your app / tests / webhook sender actually sent: point
• project_info ~124 tokens
  Get a project's public root index: every resource with record counts and URLs, custom routes, auth mode, and export links (openapi.json, types.ts, postman.json, db.json, GraphQL). No adminKey needed. Try project "demo" for the shared public playground.
• query_records ~333 tokens
  GET records from a mock resource. params is an object of query parameters, all optional: exact filters (field=value), operator suffixes (price_gte, date_lte, name_like, status_ne), full-text q, _sort/_order (or _page/_limit for pagination), select (field projection, e.g. "name,price"), _expand=<pare
• share_project ~265 tokens
  Mint (or manage) a READ-ONLY share link for a project: a browser URL you can hand to a human reviewer — they can browse the data, endpoints, snapshots and the live request inspector, but can't write and never see the adminKey. Agent workflow: build or mutate a sandbox, then share_project and give yo
• snapshots ~481 tokens
  Deterministic test fixtures + eval grading: save the project's entire dataset under a name, restore it exactly later, or DIFF it against live data (list/delete too). action:"diff" is machine-checkable grading — compares the named snapshot (expected) against live data (actual, or another snapshot via
• uptime_monitor ~645 tokens
  Free downtime alerts for any public URL — no account, armed in one call. action:"create" {url, notify?}: Mockbird GETs the url every 30 minutes from Cloudflare's network (8s timeout, 2xx/3xx = up; a timeout/TLS/DNS blip on an otherwise-up url is confirmed with a same-run retry before it counts); wit
• verdict ~564 tokens
  One call = the whole eval grade. Composes the state check (snapshot diff vs live data) with trajectory constraints on the request log into a single {pass, checks[]} verdict. Pass snapshot:"expected" to require live data to match that snapshot (author it as the answer key first via snapshots action:"
• watch_service_status ~558 tokens
  Subscribe to down/recovered alerts for any of the public mock/testing APIs tracked by check_api_status (httpbin, JSONPlaceholder, ReqRes, FakeStoreAPI, DummyJSON …). action:"subscribe" {service, notify?}: service is an id from check_api_status (or "*" for all tracked services). With notify, that web
• write_record ~173 tokens
  Create, update, or delete records in a mock resource. Writes persist (unlike JSONPlaceholder/FakeStoreAPI). POST creates (auto-id), PUT replaces, PATCH merges, DELETE removes. id required for PUT/PATCH/DELETE.
