Tell your AI agent to build your semantic layer. Open-source CLI for database introspection, metadata governance, and MCP serving. Built on OSI.
Graph extension for the dbt MetricFlow semantic layer. Author graph relations in YAML beside your metrics; a Rust compiler validates the entity contract (MetricFlow or OSI/Apache Ossie) and emits parameterized Cypher. LLMs pick named relations, never write queries. pip-installable.
Vendor-neutral semantic model that makes a warehouse legible to LLMs: validator, compilers to Snowflake semantic views, Apache Ossie, and dbt MetricFlow, an MCP server over governed metrics, and an eval that measures the accuracy gain.
Honesty & safety linter for Apache Ossie semantic models: catches cross-dialect metric drift and impure/non-deterministic expressions the schema validator can't see.
