Exocortex MCP Server

A "second brain" for AI agents — persist insights, recall past decisions, and build knowledge graphs across sessions.

Core Tools

Tool	Purpose
`exo_store_memory`	Persist insights with tags, context, and optional "painful memory" flag
`exo_recall_memories`	Search knowledge base with natural language queries and filters
`exo_link_memories`	Connect memories via relations (`related`, `extends`, `depends_on`, `supersedes`, `contradicts`, `evolved_from`, `rejected_because`, `caused_by`)
`exo_explore_related`	Discover adjacent knowledge through links, tags, and context
`exo_trace_lineage`	Trace decision evolution backward/forward through relations
`exo_curiosity_scan`	Detect contradictions, orphans, and outdated information
`exo_sleep`	Background maintenance: deduplication, orphan rescue, pattern mining
`exo_consolidate`	Extract common themes from similar memories
`exo_analyze_knowledge`	Diagnose health issues (orphans, stale content)
`exo_get_stats`	Knowledge base overview with counts and trending tags

Session Start: exo_recall_memories — retrieve relevant context
During Work: exo_store_memory — persist discoveries with structured Problem/Solution/Rationale sections and specific tags
Session End: exo_sleep — consolidate and maintain the knowledge base
