The most important MCP tool. Your coding assistant uses this to find conversations and project context that are relevant to what you’re working on. It uses semantic search (meaning-based, not just keywords) — the same search that powers the browser extension.

Parameters

ParameterTypeRequiredDescription
qstringYesThe search query (max 2,000 characters)
topLayersnumberNoMax layers to return (1-10)
projectIdsstring[]NoOnly search within these project IDs (max 100)
pinnedProjectIdsstring[]NoAlways include these projects in scoring (max 50)
renderbooleanNoIf true, returns a ready-to-use markdown context pack

What It Returns

Ranked results containing:
  • Conversation summaries and context snippets
  • Project layers that match the query
  • Relevant entities (people, tools, concepts) mentioned across your history
When render: true, returns a single markdown document your assistant can use directly for context.

When Your Assistant Uses This

  • You ask about something you’ve discussed before
  • You reference a past decision or conversation
  • Your assistant needs background context for a task
  • You say things like “remember when we discussed…” or “use the approach from last week”
