ReefAPI

ReefAPI MCP

One MCP server for 150+ 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 one tool per API

Emitting one tool per API blows past the ~30–50-tool ceiling where agents stop picking the right tool. ReefAPI uses dynamic discovery instead: five generic tools let the assistant find the right engine, then call it. Discovery is keyless; only call_engine needs a key. Failed or blocked calls cost nothing.

Tools

Tool	Keyless	What it does
search_engines(query)	✅	Ranks the catalog against English keywords or a short use-case ("company reviews", "is this domain free") and returns the best-matching engines with their actions.
get_catalog()	✅	Returns the full menu — every engine with a one-line title, grouped by category — so the model can pick semantically when a keyword search misses.
get_engine_schema(engine)	✅	Compact overview of one engine: each action with its description, required params, and return shape, kept lean so a large engine stays token-cheap.
get_action_schema(engine, action)	✅	Full detail for a single action: every parameter with type, allowed values, default, example, plus pricing and ready-to-run example params.
call_engine(engine, action, params)	🔑	Runs the action and returns the uniform { ok, data, meta, error } envelope.

The intended path is search_engines (or get_catalog) → get_engine_schema → get_action_schema → call_engine.

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 Code (CLI):

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)

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).

What you can ask

Each example below is answered by one engine; the link goes to that engine's parameters and response shape.

• "What are people saying about the new iPhone on Reddit?" → reddit
• "Get current Zillow listings in Austin under $500k." → zillow
• "Is the domain coolstartup.ai available?" → domain-availability
• "Compare Amazon prices for AirPods Pro." → amazon
• "Top Hacker News stories right now." → hackernews
• "What tech stack does stripe.com run on?" → domain-intel
• "Find remote backend jobs posted this week." → global-jobs

You never have to name the engine yourself — that is what search_engines is for. The links are there for when you want to see the exact params and fields before wiring a call.
