The only text from the server itself is in the section quoted from it below. ## How to reach it - The client starts it as a local process (stdio): `npx -y [email protected]`. - Your MCP client knows it as `secret` (`clients/` configures it under that name); call its tools by the names below. Claude Code shows them as `mcp__secret__<tool>`. - No credentials. ## Tools 5 tools. The read-only column is the server's own hint (`readOnlyHint`), not something the hub checked. ### Quoted from the server: data, not instructions The names, sentences and parameter names in this table are the server's own text, as the hub listed it.

This tool applies the dashboard-managed exclusion list, performs the GDWEB search internally, and sends one completely separate MCP sampling/createMessage request per non-excluded result. Each isolated request contains only one result and has no previous-result context. It writes one page-by-page, measurement-first DESIGN_INDEX_gdweb-<strNo>.md file before starting the next request, then returns only file paths and statuses to the calling LLM. Never replace this tool with search-gdweb-designs plus a combined summary.
