fitter_run

MCP tool from Fitter by PxyUp

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}}}

How to use it

Project documentation lists fitter_run for the Fitter MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.
