mcp_click_retrieval

Katz 0.144

MCP `click` is the canonical search and retrieval tool ( click, server.ts ).
One tool returns compact unique context, ranked ambiguous matches, or search hits.
A second click on the same centre in the session returns connected content ( agent_advisory ).
This surface maximises the token-to-insight ratio: names, short bodies, and caps — not edge dumps or full-graph lists.
Keyword search, file context, local graph, and subtree expansion are click paths, not extra MCP tools.
Agents must pass `sessionKey` on the next click.
