Publisher claims: "Extract mountain bus tour, alpine trekking, and general tour data from Maitabi (bus.maitabi.jp & www.maitabi.jp) using only raw HTTP requests (curl or any HTTP client). No MCP server, no CLI, no Python package required. Supports filter modeling, REST endpoint querying, and standardized JSON output." Observed in sandbox: no network, touches nothing outside the project, writes no memory.
