Tools & Capabilities Breakdown

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

Ready-to-Paste Client Configurations

Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
