MCP Selection Lab tools (3, 1 write)

write = sends, deletes, buys or posts
  • get_selection_reportFree

    Read and agent-enrich an existing public scan report by id; no new target request or model call.

  • scan_mcp_metadatawrite actionFree

    Create a free public report of MCP tool-description routing collisions. Reads discovery metadata (initialize/tools/list) only; never calls target business tools or spends funds. Use a public HTTP(S) URL without credentials, query or fragment. Results use at most 12 tools and 24 generated cases, not a real-model evaluation. The returned report is enriched with agent_plan candidate description-only edits and a machine-readable rerun instruction. Candidate edits are not untouched-holdout proof. Reports persist and are public by link. For an existing report use get_selection_report. Set internal_test=true for owner/CI validation so it is excluded from public scans. source is a self-reported referral bucket, not identity verification.

  • selection_lab_infoFree

    Get free service capabilities, limits, privacy and connection details; does not scan a target.
