Archivist-MCP

MCP Tool

i3T4AN/Archivist-MCP

Archivist MCP is a local-first memory server for coding agents. It persists decisions, incidents, rules, entities, and graph relationships in SQLite, then exposes them over MCP (stdio/HTTP), SSE team mode, and WebUI. Built for cross-session context continuity, conflict-safe updates, searchable recall, and auditable change history.

Install

$ npx loaditout add i3T4AN/Archivist-MCP

Platform-specific configuration:

.claude/settings.json
{
  "mcpServers": {
    "Archivist-MCP": {
      "command": "npx",
      "args": [
        "-y",
        "Archivist-MCP"
      ]
    }
  }
}

Add the config above to .claude/settings.json under the mcpServers key.

---

Archivist MCP is a memory layer for coding agents. You run it alongside your project, connect your MCP client, and the agent can persist/retrieve decisions, incidents, rules, and architecture context across sessions. WebUI is for human review and controlled write actions when you want visibility before changing memory.

Features
  • Three-tier memory model: working memory, compact core memory (core_memory.md/.json), archival graph
  • Graph + lifecycle safety: typed nodes/edges, state transitions, optimistic concurrency, immutable audit events
  • Hybrid retrieval: FTS + local embeddings + graph degree + recency with provenance and confidence
  • MCP transports: JSON-RPC over STDIO and HTTP (/mcp)
  • Team mode: SSE transport with bearer-token auth, role matrix, and project scoping
  • Controlled write workflows: conflict resolution, branch-to-project promotion, stale-memory invalidation
  • Security hardening: payload allowlists, size/type validation, sanitization, redaction, retention purge
  • Reliability tooling: integrity checks, snapshots, restore, startup recovery, rebuild index+embeddings
Quick Start
Prerequisites
  • Python 3.11+
  • macOS/Linux/Windows
1) Initialize database
