* Fix Metadata/EntityEmbeddings schema migration tail and add regression tests (#776)
The Metadata dataclass dropped its `metadata: list[Triple]` field
and EntityEmbeddings/ChunkEmbeddings settled on a singular
`vector: list[float]` field, but several call sites kept passing
`Metadata(metadata=...)` and `EntityEmbeddings(vectors=...)`. The
bugs were latent until a websocket client first hit
`/api/v1/flow/default/import/entity-contexts`, at which point the
dispatcher TypeError'd on construction.
Production fixes (5 call sites on the same migration tail):
* trustgraph-flow gateway dispatchers entity_contexts_import.py
and graph_embeddings_import.py — drop the stale
Metadata(metadata=...) kwarg; switch graph_embeddings_import
to the singular `vector` wire key.
* trustgraph-base messaging translators knowledge.py and
document_loading.py — fix decode side to read the singular
`"vector"` key, matching what their own encode sides have
always written.
* trustgraph-flow tables/knowledge.py — fix Cassandra row
deserialiser to construct EntityEmbeddings(vector=...)
instead of vectors=.
* trustgraph-flow gateway core_import/core_export — switch the
kg-core msgpack wire format to the singular `"v"`/`"vector"`
key and drop the dead `m["m"]` envelope field that referenced
the removed Metadata.metadata triples list (it was a
guaranteed KeyError on the export side).
Defense-in-depth regression coverage (32 new tests across 7 files):
* tests/contract/test_schema_field_contracts.py — pin the field
set of Metadata, EntityEmbeddings, ChunkEmbeddings,
EntityContext so any future schema rename fails CI loudly
with a clear diff.
* tests/unit/test_translators/test_knowledge_translator_roundtrip.py
and test_document_embeddings_translator_roundtrip.py -
encode→decode round-trip the affected translators end to end,
locking in the singular `"vector"` wire key.
* tests/unit/test_gateway/test_entity_contexts_import_dispatcher.py
and test_graph_embeddings_import_dispatcher.py — exercise the
websocket dispatchers' receive() path with realistic
payloads, the direct regression test for the original
production crash.
* tests/unit/test_gateway/test_core_import_export_roundtrip.py
— pack/unpack the kg-core msgpack format through the real
dispatcher classes (with KnowledgeRequestor mocked),
including a full export→import round-trip.
* tests/unit/test_tables/test_knowledge_table_store.py —
exercise the Cassandra row → schema conversion via __new__ to
bypass the live cluster connection.
Also fixes an unrelated leaked-coroutine RuntimeWarning in
test_gateway/test_service.py::test_run_method_calls_web_run_app: the
mocked aiohttp.web.run_app now closes the coroutine that Api.run() hands
it, mirroring what the real run_app would do, instead of leaving it for
the GC to complain about.
* Fix RabbitMQ request/response race and chunker Flow API drift
Two unrelated regressions surfaced after the v2.2 queue class
refactor. Bundled here because both are small and both block
production.
1. Request/response race against ephemeral RabbitMQ response
queues

Building applications that need to know things requires more than a database. TrustGraph is the context development platform: graph-native infrastructure for storing, enriching, and retrieving structured knowledge at any scale. Think like Supabase but built around context graphs: multi-model storage, semantic retrieval pipelines, portable context cores, and a full developer toolkit out of the box. Deploy locally or in the cloud. No unnecessary API keys. Just context, engineered.
The platform:
- Multi-model and multimodal database system
- Tabular/relational, key-value
- Document, graph, and vectors
- Images, video, and audio
- Automated data ingest and loading
- Quick ingest with semantic similarity retrieval
- Ontology structuring for precision retrieval
- Out-of-the-box RAG pipelines
- DocumentRAG
- GraphRAG
- OntologyRAG
- 3D GraphViz for exploring context
- Fully Agentic System
- Single Agent
- Multi Agent
- MCP integration
- Run anywhere
- Deploy locally with Docker
- Deploy in cloud with Kubernetes
- Support for all major LLMs
- API support for Anthropic, Cohere, Gemini, Mistral, OpenAI, and others
- Model inferencing with vLLM, Ollama, TGI, LM Studio, and Llamafiles
- Developer friendly
No API Keys Required
How many times have you cloned a repo and opened the .env.example to see the dozens of API keys for 3rd party dependencies needed to make the services work? There are only 3 things in TrustGraph that might need an API key:
- 3rd party LLM services like Anthropic, Cohere, Gemini, Mistral, OpenAI, etc.
- 3rd party OCR like Mistral OCR
- The API key you set for the TrustGraph API gateway
Everything else is included.
- Managed Multi-model storage in Cassandra
- Managed Vector embedding storage in Qdrant
- Managed File and Object storage in Garage (S3 compatible)
- Managed High-speed Pub/Sub messaging fabric with Pulsar
- Complete LLM inferencing stack for open LLMs with vLLM, TGI, Ollama, LM Studio, and Llamafiles
Quickstart
There's no need to clone this repo, unless you want to build from source. TrustGraph is a fully containerized app that deploys as a set of Docker containers. To configure TrustGraph on the command line:
npx @trustgraph/config
The config process will generate an app config that can be run locally with Docker, Podman, or Minikube. The process will output:
deploy.zipwith either adocker-compose.yamlfile for a Docker/Podman orresources.yamlfor Kubernetes- Deployment instructions as

For a browser based configuration, try the Configuration Terminal.

Getting Started with TrustGraph
Workbench
The Workbench provides tools for all major features of TrustGraph. The Workbench is on port 8888 by default.
- Vector Search: Search the installed knowledge bases
- Agentic, GraphRAG and LLM Chat: Chat interface for agents, GraphRAG queries, or direct to LLMs
- Relationships: Analyze deep relationships in the installed knowledge bases
- Graph Visualizer: 3D GraphViz of the installed knowledge bases
- Library: Staging area for installing knowledge bases
- Flow Classes: Workflow preset configurations
- Flows: Create custom workflows and adjust LLM parameters during runtime
- Knowledge Cores: Manage resuable knowledge bases
- Prompts: Manage and adjust prompts during runtime
- Schemas: Define custom schemas for structured data knowledge bases
- Ontologies: Define custom ontologies for unstructured data knowledge bases
- Agent Tools: Define tools with collections, knowledge cores, MCP connections, and tool groups
- MCP Tools: Connect to MCP servers
TypeScript Library for UIs
There are 3 libraries for quick UI integration of TrustGraph services.
Context Cores
A Context Core is a portable, versioned bundle of context that you can ship between projects and environments, pin in production, and reuse across agents. It packages the “stuff agents need to know” (structured knowledge + embeddings + evidence + policies) into a single artifact, so you can treat context like code: build it, test it, version it, promote it, and roll it back. TrustGraph is built to support this kind of end-to-end context engineering and orchestration workflow.
What’s inside a Context Core
A Context Core typically includes:
- Ontology (your domain schema) and mappings
- Context Graph (entities, relationships, supporting evidence)
- Embeddings / vector indexes for fast semantic entry-point lookup
- Source manifests + provenance (where facts came from, when, and how they were derived)
- Retrieval policies (traversal rules, freshness, authority ranking)
