What it does

MeMesh gives Claude Code persistent memory through 3 MCP tools, 2 hooks, and a CLI dashboard:

MCP Tools

ToolDescription
rememberStore knowledge — entities with observations, relations, and tags
recallSearch stored knowledge via FTS5 full-text search with optional tag filtering
forgetDelete stored knowledge by name (cascades to observations, relations, tags)

Hooks

HookEventWhat
Session StartSessionStartAuto-recalls project-specific + recent global memories
Post CommitPostToolUse (Bash)Records git commits as knowledge entities

CLI

MeMesh Dashboard

How it works

  • Storage: SQLite database at ~/.memesh/knowledge-graph.db
  • Search: FTS5 full-text search (no vector embeddings)
  • Isolation: Tag-based project filtering (project:<name>)
  • Schema: entities, observations, relations, tags + FTS5 virtual table
  • Validation: All tool inputs validated with Zod schemas
