Korg Recall Mcp

new1direction/korg

This server connects Claude to Korg's causally-ordered event ledger, letting you log agent decisions across sessions and recall them by semantic meaning rather than exact text match. It exposes MCP tools that append cognitive events (edits, tool calls, prompts) to an immutable, HLC-timestamped journal you can rewind, replay, or fork. The ledger lives locally and persists across Claude Code, Codex, or Grok sessions, so you can query "when did I refactor the auth layer" weeks later and get back the exact event sequence. Useful if you're running long-lived coding workflows and want Git-style time travel for LLM actions, or if you need cross-session memory that survives context window limits. The agent must explicitly call the logging tools; passive capture isn't available yet.

Readme

korg

A tamper-evident, SHA-256-chained ledger for AI agents. Every step your agent takes is recorded in a hash chain anyone can verify — edit one event and the chain names it. No trust in the producer, no blockchain.

30-second quickstart

Build the standalone verifier (~10s cold — it compiles only the ledger crates), verify a recorded Claude Code session, then rewrite one event and watch the chain catch it:

git clone https://github.com/New1Direction/korg && cd korg
cargo build --release -p korg-verify
cp spec/korg-ledger-v1/web/samples/session.jsonl /tmp/session.jsonl
