fitter_run_file
Same as fitterrun but reads the config from a local .json/.yaml file
How to use it
fitter_run_file is exposed by the Fitter MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), and the fitter_run_file tool becomes available to the model automatically. See the full listing for setup details and every tool this server provides.

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
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}}}
Same as fitterrun but downloads the config from an HTTP(S) URL, e.g. a raw GitHub link
Validate a config without executing it (structure, responsetype, connector data source, model). Useful while iterating on a config
