One MCP for 160+ live web-data APIs — clean JSON from sites that block scrapers.

Access 160+ live web-data APIs with clean JSON output from scraper-blocking sites.

Captured live from the server via tools/list.

search_engines

Find the right ReefAPI engine for a task — pass ENGLISH keywords or a short natural-language use-case ("detect a website's tech stack", "company reviews", "check a package for vulnerabilities", "is this domain available"). The catalog is in English: if the end-user asked in another language, translate their INTENT into English keywords first (you are an LLM — do this inline). Ranks engines by how well the query matches each engine's name/title/category/ACTION descriptions (stem-matched, so plurals/word-forms still hit). Empty query = list all. Returns name/title/category/actions + match score. Call this FIRST, then get_engine_schema(engine) to pick an action. This is a fast keyword pre-filter — if the right engine isn't in the results (or you want to be sure), call get_catalog and pick from the full list YOURSELF (you semantically match any language/phrasing better than keywords).

Parameters (1)

querystring
English keywords or a short use-case, e.g. 'company reviews', 'detect a website's tech stack', or 'is this domain available'. Translate non-English intent to English first. Empty = list all engines.

get_engine_schema

COMPACT overview of ONE engine: every action with its description, required params and what it returns — but NOT the full param detail (kept lean so a 90-action engine stays token-cheap). Call this after search_engines to pick the right ACTION, then get_action_schema(engine, action) for that action's full params before call_engine.

Parameters (1)

enginestringrequired
The engine's name (the `engine`/`name` field from search_engines or get_catalog, e.g. 'zillow', 'amazon'). Returns each action with its description, required params, and what it returns.

get_action_schema

FULL detail for ONE engine action: every parameter (type, required, description, allowed_values dropdown, default, example, min/max), what it returns, pricing, and a ready-to-run example_params. Call this right before call_engine so you send valid params — invalid enum values are rejected with the allowed list.

Parameters (2)

enginestringrequired
The engine's name (e.g. 'zillow'), as returned by search_engines or get_catalog.
actionstringrequired
The action's name on that engine (from get_engine_schema, e.g. 'search'). Returns the full param detail (type, required, allowed_values, default, example, min/max), what it returns, pricing, and ready-to-run example_params.

call_engine

Call a ReefAPI engine action — POST /<engine>/v1/<action> with `params`. Returns the uniform { ok, data, meta, error } envelope. Get param names from get_engine_schema first. Needs YOUR ReefAPI key (the local server reads REEFAPI_KEY; the hosted server reads the `Authorization: Bearer ak_live_...` header you configure on the connection). Get a key at https://reefapi.com. Failed calls cost no credits.

Parameters (3)

enginestringrequired
The engine's name to call (e.g. 'zillow'), as returned by search_engines or get_catalog.
actionstringrequired
The action to run on that engine (e.g. 'search'), as listed by get_engine_schema.
paramsany
The action's parameters as a JSON object, e.g. {'query': 'NYC'}. Get the valid param names and values from get_action_schema first. Omit or pass null for actions that take none.

get_catalog

The FULL ReefAPI catalog — EVERY engine with its one-line title, grouped by category. This is the whole menu (≈ a few thousand tokens); SCAN IT AND PICK THE BEST ENGINE YOURSELF. You are an LLM, so you match the user's intent semantically — across ANY language, typo, or phrasing — far better than a keyword search can. Use this whenever search_engines didn't surface the right engine (or to be sure you didn't miss a better one). After you pick: get_engine_schema(engine) -> get_action_schema -> call_engine.

No parameters.

ReefAPI MCP

One MCP server for 160+ live web-data APIs — search engines, social media, e-commerce, real estate, jobs, travel, news, finance, and company/domain/people intelligence. The assistant discovers the right engine, then pulls clean JSON from sites that block scrapers (captcha, login, JS, anti-bot).

Why one server, not 160 tools

Emitting one tool per API blows past the ~30–50-tool ceiling where agents stop picking the right tool. ReefAPI uses dynamic discovery — 4 generic tools let the assistant find the right engine, then call it:

Tool	Keyless	What it does
`search_engines(query)`	✅	Find the right engine by intent ("company reviews", "is this domain free")
`get_catalog()`	✅	The full menu of every engine, grouped by category
`get_engine_schema(engine)`	✅	An engine's actions, params, and return shapes
`get_action_schema(engine, action)`	✅	Full params for one action
`call_engine(engine, action, params)`	🔑	Run it → clean `{ ok, data, meta, error }` JSON

Discovery is keyless; only call_engine needs a key. Failed or blocked calls cost nothing.

Connect (remote — recommended)

Add to Claude Desktop, Cursor, Windsurf, or any client that takes a remote MCP URL:

  "mcpServers": {
    "reefapi": {
      "url": "https://api.reefapi.com/mcp",
      "headers": { "Authorization": "Bearer YOUR_REEFAPI_KEY" }
    }
  }
}

claude mcp add --transport http reefapi https://api.reefapi.com/mcp \
  --header "Authorization: Bearer YOUR_REEFAPI_KEY"

Get a free key (1,000 credits, no card) at https://reefapi.com.

Run it locally (stdio)

bash

pip install -r requirements.txt
export REEFAPI_KEY=ak_live_your_key   # Windows: set REEFAPI_KEY=...
python server.py                      # stdio transport

Then point your client at python /path/to/server.py. The same file also serves the streamable-HTTP transport with MCP_TRANSPORT=streamable-http (used by the hosted endpoint above).
