Which MCP Server Should You Choose?
Choose Open WebSearch when:
You need dedicated capabilities in the Search & Data Extraction domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Search the web using multiple engines (e.g., Baidu, Bing, DuckDuckGo, CSDN, Exa, Brave, Juejin(掘金), Startpage, Sogou(搜狗)) with no API key required. searchMode meanings: omit or set auto to use the server configured SEARCH_MODE; request forces request-based search; playwright forces browser-based search.

Fitter Tools (5)
fitter_run
Run a Fitter config passed inline (JSON or YAML string) and return the extracted data as JSON. Accepts an optional `input` value available in the config via `{{{FromInput=.}}}` / `{{{FromInput=json.path}}}
fitter_run_file
Same as `fitter_run` but reads the config from a local `.json`/`.yaml` file
fitter_run_url
Same as `fitter_run` but downloads the config from an HTTP(S) URL, e.g. a raw GitHub link
fitter_validate_config
Validate a config without executing it (structure, `response_type`, connector data source, model). Useful while iterating on a config
fitter_config_reference
Return a condensed reference of the whole config format (connectors, parsers, model/field schema, placeholders, notifiers, references, limits) with working examples, so the model can author configs without external docs
