README

Mnemograph

A persistent, event-sourced knowledge graph for AI coding agents. Unlike simple key-value memory, Mnemograph captures entities, relations, and observations — enabling semantic search, tiered context retrieval, and git-based version control of your AI's memory.

Works with: Claude Code, opencode, codex CLI, Zed, Continue.dev, and any MCP-compatible agent.

Why Mnemograph?

AI coding sessions are ephemeral. Mnemograph gives your AI partner persistent memory that:

Survives across sessions — decisions, patterns, learnings persist
Supports semantic search — find relevant context by meaning, not just keywords
Provides tiered retrieval — shallow summaries to deep subgraphs based on need
Versions like code — branch, commit, diff, revert your knowledge graph
Enables collaboration — share memory repos across users or projects

Memory Scope: Local vs Global

Before using mnemograph, decide where to store memory:

Scope	Path	Use When
Project-local	`./.claude/memory`	Knowledge specific to this repo (architecture, decisions, patterns)
Global	`~/.claude/memory`	Cross-project knowledge (personal learnings, universal patterns, preferences)
Custom	Any path via `MEMORY_PATH`	Shared team memory, org-wide knowledge bases

Important: Agents should ask the user which scope to use when first setting up mnemograph for a project. This affects where knowledge is stored and whether it's shared across projects.

# Project-local (default)
MEMORY_PATH=".claude/memory"

# Global (cross-project)
MEMORY_PATH="$HOME/.claude/memory"

# CLI: use --global flag
mnemograph --global status
mnemograph --global graph

Quick Start

Option 1: Let Claude Code install it

Give Claude Code this repo URL and ask it to set up mnemograph:

https://github.com/tm42/mnemograph

Or point Claude to the setup instructions directly:

Read https://raw.githubusercontent.com/tm42/mnemograph/main/SETUP_CLAUDE_CODE.md and follow them

Option 2: Manual installation

# Install from PyPI
pip install mnemograph

# Add to Claude Code (global, available in all projects)
claude mcp add --scope user mnemograph \
  -e MEMORY_PATH="$HOME/.claude/memory" \
  -- uvx mnemograph

# Initialize memory directory
mkdir -p ~/.claude/memory

Option 3: Other MCP Clients

Each MCP client has a different configuration format. See UNIVERSAL_MCP_COMPATIBILITY.md for copy-paste configs for:

opencode — ~/.config/opencode/opencode.json
Codex CLI — ~/.codex/config.yaml
Zed — ~/.config/zed/settings.json
Continue.dev — ~/.continue/config.json

The key environment variable is MEMORY_PATH — set it to where you want the knowledge graph stored.

Option 4: Install from source

git clone https://github.com/tm42/mnemograph.git
cd mnemograph
uv sync

# Add to Claude Code (or adapt for your MCP client)
claude mcp add --scope user mnemograph \
  -e MEMORY_PATH="$HOME/.claude/memory" \
  -- uv run --directory /path/to/mnemograph mnemograph

Usage

MCP Tools (used by any agent)

Mnemograph exposes these tools via MCP:

Core Operations:

Tool	Description
`remember`	Primary storage: Store knowledge atomically (entity + observations + relations in one call)
`recall`	Primary retrieval: Get relevant context with auto token management. Use `focus=['Entity']` for full details. Default output is human-readable prose.
`create_entities`	Create entities (auto-blocks duplicates >80% match)
`create_relations`	Link entities with typed edges (implements, uses, decided_for, etc.)
`add_observations`	Add facts/notes to existing entities
`read_graph`	Get the full knowledge graph (warning: may be large)
`delete_entities`	Remove entities
