search_agentsSearch the lcas directory of ERC-8004 agents. Returns newest first, one entry per group of copies, with which service types passed lcas's last check. Use get_agent for full details.
find_toolsFind single MCP tools or A2A skills that do something, across all agents. Only endpoints that passed lcas's last daily check. Ordered by reliability, not by a score: endpoints whose weekly live test passed first, then by days working in the last 30, then by how well the words ma…
get_agentDetails of one agent: each declared endpoint with lcas's check result, 30-day history and all-time working days, since when the current owner holds it, the weekly live test where one exists (one read-only tool called, or one skill example sent), its MCP tools or A2A skills, copi…

directory_statusWhich chains lcas indexes and how far each is synced.
