What it does

free is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.

From the publisher's description, Electra Index matched it to one capability: document understanding. That makes it a candidate for tasks such as analyze financial documents or analyze patents.

Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence) and are not a test of the tool.

6 tools offered to AI assistants

  • get_catalog · Mart402 product catalog: all products, prices, payment config, error codes, rate limits. Free.
  • quote_parse · Free quote for PDF parsing: page count, route (text/scan-OCR) and the exact final price, before any payment. Use the returned quote_id with parse_document (on /mcp or /mcp/docs).
  • search_x402_services · Search the Market402 verified index of the whole x402 economy by capability (e.g. 'ocr', 'market-data'). Every result is a real, probed resource with a measured 402 Score. Free.
  • get_sample · Free recorded sample response for a paid product (from real production runs, marked sample:true) - see the exact response shape before paying anything. Available: document-pipeline, enrich, extract, jp-bonus-net, jp-business-days, jp-compan
  • portrait_precheck · FREE analyzability check before paying for portrait_analysis: is a face detectable, is the photo quality good enough (clipping/color cast)? Deterministic, no LLM. 10/hour/IP.
  • operator_history · Free 12-week measured score history for any x402 operator from the Market402 index (weekly series, trend, volatility, badge). Check a seller's record before your agent pays an unfamiliar endpoint.

How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method
