Graphiti Local

Local memory for your agents. You approve what they learn.

Retrieve project decisions through six read-only MCP tools or the kg CLI. Proposed updates stay in a separate queue until a human approves and applies them. Ollama handles local inference; embedded LadybugDB stores the graph. No Docker or cloud API key is needed for the local setup.

Captured output excerpts with pauses condensed. Measured results and limitations.

Try it in one command

uvx --from git+https://github.com/renezander030/graphiti-local kg-demo

Answers a question against a small synthetic graph shipped with the package. No Ollama, no model downloads, no database setup: retrieval runs on keywords alone, so nothing contacts a model. Ask your own question by passing it as an argument.

This is the read path only. Building a graph from your own text needs extraction, which needs a model, and that is the full setup below.

Try it locally

Install uv and Ollama, then start Ollama. Setup downloads need internet access. Run these commands in bash or zsh:

git clone https://github.com/renezander030/graphiti-local.git
cd graphiti-local
uv sync --frozen
ollama pull qwen2.5:7b
ollama pull nomic-embed-text
export GRAPHITI_LOCAL_CONFIG="$PWD/config/ollama.example.yaml"
export KG_WORKSPACE_DIR="$PWD/workspace/local-demo"
export KG_LADYBUG_PATH="$KG_WORKSPACE_DIR/graph.ladybug"
uv run --frozen kg-ladybug-setup --database "$KG_LADYBUG_PATH" --apply
uv run --frozen kg doctor
uv run --frozen kg-ingest examples/local_memory_demo.jsonl --apply
uv run --frozen kg ask "Which database does Aurora Analytics use?" example

The synthetic example returns DuckDB. Follow the complete walkthrough to propose PostgreSQL, review and apply that update, and retrieve it from an MCP client. Model extraction can be wrong; inspect the returned facts and validity timestamps.

To review extraction before it touches the configured graph, run kg-ingest INPUT --review-output review.jsonl, inspect the snapshot, and mark every fact in the generated review.jsonl.review.jsonl file as accept, refuse, or contested. The printed restore command refuses unresolved decisions and promotes a checksum-sealed snapshot containing accepted facts only. Searches return current facts by default; kg ask --history is the explicit historical view.

kg-ingest also accepts a Markdown/text file or a directory tree directly. Large documents split at stable text boundaries. Transient writes retry with one stable episode id; ingest-receipts.jsonl and ingest-failures.jsonl in the workspace show exactly what landed and what still needs attention.

Multiple users on Ladybug

Give each user a group, and each group its own Ladybug file:

graph:
  groups: [alice, bob]
database:
  provider: ladybug
  ladybug:
    layout: per-group          # default: single, one file for every group
    directory: ./workspace/groups
server:
  transport: streamable-http
  auth:
    tokens:
      - {name: alice, token: "${ALICE_TOKEN}", groups: [alice]}
      - {name: bob, token: "${BOB_TOKEN}", groups: [bob]}

Each file is named by the SHA-256 of its group, so no group id can point outside the directory. Reads, kg ask and the drain open only the file of the group they address; a token granted alice never opens Bob's file. A read names one group, or the token's single group is used. For a tenant boundary inside one database server, use FalkorDB or Neo4j.

Is it a fit?

Use it for local agent memory with explicit human review. Skip it if you need agents to write through MCP or want a hosted service without local setup. FalkorDB and Neo4j are also supported.
