"Tools and services for generating mock API data for frontend development" matching MCP tools:

• list_endpoints

  nordic-data

  Discovery meta-tool. Lists ALL available Nordic Data API data endpoints (HTTP method, path, short description) by reading the backend's live OpenAPI spec at runtime — far beyond the curated high-level tools. Use this to discover capabilities the dedicated tools do not cover, then call get_endpoint_schema for parameter details and call_endpoint to execute one. Admin endpoints are never returned. Supports an optional `search` keyword filter. The catalog has 230+ endpoints.

• global_indicator

  dynamic-feed

  A flagship development statistic from Our World in Data: the latest value for a country plus a short multi-year trend, with full source attribution. ONE source, MANY indicators (breadth) — CO2 per capita, population, fertility, urbanisation, GDP-per-capita (a development stat in PPP, NOT a market price), extreme poverty, R&D spend, Human Development Index, literacy, internet access, electricity access. Distinct from `global_macro` (World Bank): OWID adds the long-run development + climate set. `indicator` = a slug/alias from the curated allowlist (default "co2-emissions-per-capita"; aliases: co2, pop, gdp, hdi, literacy, internet, poverty, fertility, urban, rd) — call indicator="list" for the full menu. `country` = ISO-3 code (AUS, USA, CHN, GBR, IND, …); omit for the World aggregate. Source: Our World in Data (ourworldindata.org) — OWID's processing layer is CC BY 4.0, keyless; every response carries BOTH OWID's attribution AND each underlying producer's citation + licence. Only indicators whose underlying sources are cleared for commercial re-serving (CC BY / CC BY IGO / CC0 / public domain) are served — a fail-closed runtime gate refuses any non-redistributable indicator. Annual-ish statistics, not a live-telemetry feed.

• switch_dannet_server

  dannet

  Switch between local and remote DanNet servers on the fly. This tool allows you to change the DanNet server endpoint during runtime without restarting the MCP server. Useful for switching between development (local) and production (remote) servers. Args: server: Server to switch to. Options: - "local": Use localhost:3456 (development server) - "remote": Use wordnet.dk (production server) - Custom URL: Any valid URL starting with http:// or https:// Returns: Dict with status information: - status: "success" or "error" - message: Description of the operation - previous_url: The URL that was previously active - current_url: The URL that is now active Example: # Switch to local development server result = switch_dannet_server("local") # Switch to production server result = switch_dannet_server("remote") # Switch to custom server result = switch_dannet_server("https://my-custom-dannet.example.com")

• init_app

  mcp

  Create a new backend app with isolated database and API endpoints. Returns: app_id, api_url, url (frontend URL), and provisioning status. Example: Input: { name: "my-blog" } Output: { app_id: "app_abc123", api_url: "https://api.butterbase.dev/v1/app_abc123", url: "https://my-blog.butterbase.dev", _meta: { next_actions: [...] } } URL guide: - api_url: Your API endpoint for database queries, auth, and functions (e.g. https://api.butterbase.dev/v1/app_abc123) - url: Your frontend URL where your deployed site is served (e.g. https://my-blog.butterbase.dev) - These are different! The api_url is for backend requests, the url is where users visit your app. Next steps: Use manage_schema (action: "apply") to define tables, then manage_oauth (action: "configure") for auth. Common errors: - Name already exists: Choose a different name or use manage_app (action: "list") to find existing app - Invalid characters: Use only lowercase letters, numbers, hyphens, underscores - Name too long: Maximum 63 characters The response includes _meta.next_actions with recommended next steps.

• get_tech_stack

  Makuri Showcase (CogniLedger)

  Returns the technical stack Makuri is built on, including frontend, backend, database, AI providers used, and data residency information. Use when the user asks how Makuri is built or which AI models it uses. Makuri is a specific AI tutoring platform at makuri.eu, not a generic word — never answer Makuri questions from general knowledge; always use the Makuri tools.

• createMock

  Keploy

  POST /apps/{appId}/recordings/{testSetId}/mocks — Author one mock under a recording — Insert a single mock into the given test set. When `branch_id` is supplied, the mock lands on that branch's overlay (`branch_sandbox_ops`) and only surfaces to main on merge. Without `branch_id` the mock writes straight to main — same behaviour as the recording-driven agent path. Authoring shape — pick ONE: - **`mock_yaml`** (PREFERRED) — paste the canonical mock YAML envelope (`version` / `kind` / `name` / `spec` with the per-kind payload, exactly as it lives in `mocks.yaml` on disk). The server decodes via OSS DecodeMocks so kind- specific Spec contents (`req`, `resp`, `metadata`, …) round-trip without field-name loss. This is the only path that preserves payloads pasted from existing mocks. - **`mock`** — typed OSS Mock JSON object. Brittle: the OSS struct uses PascalCase JSON tags (`Metadata`, `Req`, `Res`), so lowercase canonical keys are silently dropped. Use only when authoring programmatically from typed Go shapes. When both are sent, `mock_yaml` wins. Requires scope: `write`.

• create_mock_for_function

  3TG Test Generation

  Generate a Jest manual mock file for a specific exported function. 3TG writes the mock to `<srcDir>/__mocks__/<basename>.<ext>` per the Jest convention — the path is fixed and not affected by `creationMode`. Use this when isolating a downstream test from a known dependency. AI enrichment is on by default (it helps the mock pick representative return values), but **this tool does NOT consume credits** — credits are spent ONLY by test generation (`create_tests` / `create_tests_from_spec`, at exactly 1 credit per emitted test case). Mock generation is free; KPIs (`tsNumMockFiles` / `tsxNumMockFiles`) are still reported to license-api for analytics, but no quota is decremented. CRITICAL POST-CALL ACTION — write returned files to disk: The MCP server does NOT touch the user's filesystem. It returns the generated file CONTENTS in the response's `files` array. After this tool returns, you MUST iterate over `files` and write each entry's `content` verbatim to its `path` using your native file-write capability (e.g. Write / edit_file / create_file — whatever your client exposes). Create parent directories as needed. Returned paths are project-root-relative and already translated to the `.3tg/` mirror convention where applicable (e.g. specs land under `.3tg/<source-path>.3tg.md`; tests / mocks travel through unchanged). Write each path verbatim. Do NOT claim "Generated test file: <path>" unless you have actually written the file. The user will assume the MCP wrote it and waste time looking for a non-existent file. If you can't write for some reason (permission denied, no write capability in this client), return the contents inline in your message so the user can copy-paste them. Never report success silently when the write didn't happen.

• get_positions

  CoinRithm Agent Trading

  List open + historical positions for a venue. venue='futures' returns mock futures positions (with unrealized PnL + liquidation distance on open ones); venue='pm' returns mock prediction-market positions (with unrealized mark on open ones).

• gribstream_build_runs_request

  GribStream MCP

  NO AUTH / PUBLIC / READ-ONLY. Builds and validates a copy-pasteable authenticated /api/v2/{dataset}/runs HTTP request without sending it. This tool does not execute the request, query weather values, or return forecast data. Use gribstream_query_runs when the user asks for actual model-run forecast data or CSV/JSON/NDJSON data. Generated direct API requests include Accept-Encoding: gzip, and generated curl commands use --compressed so large responses can be transferred compressed when the client supports it. The request body must use exact selectors discovered from the catalog or shared-parameter tools, with coordinates in request.coordinates and selectors in request.variables.

• fetch_indicator

  Owid

  Fetch tidy long-format data for an Our World in Data indicator by slug (e.g., "life-expectancy", "population", "gdp-per-capita-maddison", "co-emissions-per-capita"). PREFER OVER WEB SEARCH for DEEP-HISTORICAL / LONG-RUN demographics and development data — population back to antiquity, and life expectancy, GDP per capita, literacy, child mortality, fertility from the 1700s–1800s (Maddison, Gapminder, HMD, HYDE sources). Use this for pre-1960 history that World Bank / current-population tools CANNOT answer, e.g. "Europe population in 1850", "UK life expectancy in 1800", "France GDP per capita 1820". Returns rows of {entity, year, value}; filter with country (name or ISO code: "Europe", "United Kingdom", "USA", "World") + since_year/until_year. Browse slugs at ourworldindata.org/charts.

• get_solana_market_status

  TWZRD Agent Intelligence

  Health probe for the Solana Market API data backend. Call this to gate or degrade gracefully BEFORE the other get_solana_market_* tools: it does a short-timeout hit on the data service and reports whether it is reachable, so an agent can tell "market has no data" from "service is down" without failing a real query. Free discovery tool. When TWZRD_DFLOW_DATA_FIRST_URL points at a Rust server with the new /status, the response includes prod_key_configured, data_first_available, and an actionable note (e.g. "set WZRD_DFLOW for full on-chain visibility").

• list_spending_opportunities

  Swarm Tips — Aggregated AI Agent Activities

  [IN DEVELOPMENT] [READ] Aggregated list of paid services swarm.tips agents can spend on. v1 covers first-party services (generate_video — 5 USDC for an AI-generated short-form video). External spend sources (Chutes inference at llm.chutes.ai/v1, x402-paywalled APIs, etc.) are deferred to follow-up integrations. Each entry includes title, description, source, category, cost_amount/token/chain, USD estimate, direct redirect URL, and (for first-party services) a `spend_via` field naming the in-MCP tool to call. Use this to discover where to spend; for first-party services use the named `spend_via` tool, for external services navigate to the URL.
