LocalStateBackend becomes ClusterStore: every stored byte — state ledger, lock, recovery sidecars, approval artifacts — now flows through the engine's StorageAdapter, making file:// and s3:// one code path. Behavior on the file backend is byte-compatible (layout, CAS semantics, diagnostics, lock release timing) and the entire pre-existing suite passes unchanged. Mechanics: the ledger CAS keeps its public sha256 vocabulary while the physical swap is token-conditioned (ETag If-Match on S3 via PR #186's primitives; content-token + temp/rename locally — the pre-port semantics); the lock is a create-only put (genuinely cross-machine on object stores) with deterministic drop-release locally and best-effort spawned release on S3; sidecars/approvals address by URI (SweepOutcome and the executors carry strings); sweep row-1 retirement joins the uniform deferred post-CAS cleanup. ClusterStore also gains the catalog-payload and graph-root methods that commit 2 wires in. Async ripple: status/force-unlock/serving-snapshot and the server's settings loader chain go async (CLI dispatch and ~20 test hosts follow, mechanically). tokio joins the cluster crate's runtime deps for the lock guard's handle.

Omnigraph
Lakehouse native graph engine built for context assembly
Omnigraph acts as operational state & coordination layer for agents
- Git-style versioning & branching
- Multimodal retrieval (graph+vector/fts+filters) optimized for context assembly
- Object storage native (S3, RustFS)
- Native blob-as-data support (docs, images, videos, etc)
- VPC, On-prem, hybrid deployment
Lanceformat as open storage layer
| AS CODE | What it means |
|---|---|
| Schema AS CODE | Typed .pg schemas, planned, applied, enforced |
| Context AS CODE | Linted queries & agentic nudges, versioned and reusable |
| Security AS CODE | Cedar policies enforced server-side on every mutation |
| Dashboards AS CODE | Declarative views & controls over the graph (coming) |
Core Use Cases
| Use case | What it's for |
|---|---|
| Company brain | Org knowledge unified into one queryable graph |
| Context graph | Decision traces and codified tribal knowledge |
| Agentic memory | Durable, versioned memory for long-running agents |
| Dev graph | Issues & dependency model for coding agents |
| R&D data layer | Experiments & trials data written into branches |
| ML workflows | Versioned, branchable graphs for training & eval |
| Karpathy's LLM wiki | A living, agent-updatable knowledge base |
Quick Install
curl -fsSL https://raw.githubusercontent.com/ModernRelay/omnigraph/main/scripts/install.sh | bash
This installs omnigraph and omnigraph-server into ~/.local/bin from
published release binaries.
Or install with Homebrew:
brew tap ModernRelay/tap
brew install ModernRelay/tap/omnigraph
For starter graphs and agent skills to bootstrap and operate Omnigraph, see ModernRelay/omnigraph-cookbooks.
One-Command Local RustFS Bootstrap
curl -fsSL https://raw.githubusercontent.com/ModernRelay/omnigraph/main/scripts/local-rustfs-bootstrap.sh | bash
That bootstrap:
- starts RustFS on
127.0.0.1:9000 - creates a bucket and S3-backed graph
- loads the checked-in context fixture
- launches
omnigraph-serveron127.0.0.1:8080
Docker must be installed and running first.
The RustFS bootstrap prefers the rolling edge binaries and only falls back to
source builds when release assets are unavailable.
If a previous run left objects under the same graph prefix but did not finish
initializing the graph, rerun with RESET_REPO=1 or set PREFIX to a new
value.
Common Commands
The same URI works for local paths, s3://…, or http://host:port.
omnigraph init --schema ./schema.pg ./graph.omni
omnigraph load --data ./data.jsonl ./graph.omni
omnigraph read --query ./queries.gq --name get_person --params '{"name":"Alice"}' ./graph.omni
omnigraph change --query ./queries.gq --name insert_person --params '{"name":"Mina"}' ./graph.omni
omnigraph branch create --from main feature-x ./graph.omni
omnigraph branch merge feature-x --into main ./graph.omni
See docs/user/cli.md for schema apply, snapshots, data loading, commits, and policy commands.
Clients
For programmatic access to a running omnigraph-server:
-
TypeScript SDK —
@modernrelay/omnigraph(source). Instance-per-client, typed errors, camelCase types, async-iterator streaming export.npm install @modernrelay/omnigraph -
Model Context Protocol server —
@modernrelay/omnigraph-mcp(source). Bridges Omnigraph to LLM hosts (Claude Desktop, Claude Code, …) over stdio. Exposes tools and resources for schema, branches, queries, mutations, ingest, and bundles curated best-practices guidance from the cookbook.npm install -g @modernrelay/omnigraph-mcp
Both packages are versioned in lockstep with omnigraph-server on major.minor: @modernrelay/omnigraph@X.Y.* targets omnigraph-server@X.Y.*. See ModernRelay/omnigraph-ts for the monorepo.

Build And Test
cargo build --workspace
cargo check --workspace
cargo test --workspace
Notes:
- Rust stable toolchain, edition 2024
- CI runs
cargo test --workspace --locked - Full CI and some local test flows require
protobuf-compiler - S3 integration tests expect an S3-compatible endpoint such as RustFS
