reefapi
Description
One MCP for 160+ live web-data APIs — search, social, e-commerce, real estate, jobs, travel, news, finance. The assistant discovers the right engine, then pulls clean JSON from sites that block scrapers (captcha, login, JS, anti-bot). Discovery is keyless; calls use a free ReefAPI key.

Agent readability score
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
Agent readability score
Strengths
- Detailed parameter documentation in get_action_schema
- Clear workflow from search_engines → get_engine_schema → call_engine
- Comprehensive catalog access via get_catalog
Weaknesses
- search_engines requires English input despite LLM's multilingual capabilities
- get_engine_schema and get_catalog both handle engine discovery but with different scopes
- call_engine's param requirements are mentioned but not explicitly defined in descriptions
search_engines— requires English input despite LLM's multilingual capabilitiesget_engine_schema— describes compact overview but doesn't clarify what's omittedcall_engine— param requirements mentioned but not explicitly definedget_catalog— full catalog access may overwhelm agents with too many options

Advice
Schema compliance
tools/list structure, inputSchema validity, and a functional smoke test — the components of the 0-100 score.
- tools/list schema valid
- inputSchema is valid JSON Schema
- Smoke test not run this round
- Cold-start: cold 57ms → warm 62ms (penalty 0ms)
