Fitter turns scraping into declarative MCP configs and ships a browser playground
PyxRu · reddit · 2026-07-26
Fitter is an MCP-based scraper that uses declarative JSON/YAML configs instead of code. The connector layer can talk to HTTP endpoints, headless browsers, or static values, while extraction uses gjson paths, CSS selectors, XPath, or PDF text.
Because the configs are plain data, an LLM can generate them. The author ships a browser-based WebAssembly playground on GitHub Pages, plus a form builder that emits config JSON. The same config can then be reused from cron or the CLI, turning a one-off extraction into a durable workflow. Install options include a binary release, Claude Desktop’s .mcpb bundle, and an HTTP mode with bearer auth for teams.
