pretensor index. Every database driver ships as an extra — PostgreSQL via pretensor[postgres], Snowflake via pretensor[snowflake], BigQuery via pretensor[bigquery].Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.
| Tool | What it does |
|---|---|
| list_databases | List indexed database connections with table counts and staleness. |
| schema | Inspect node labels, edge types, and available properties before writing Cypher. |
| query | BM25 keyword search over table and entity metadata. Hybrid BM25 + cosine RRF rerank when [embeddings] is installed and tables carry vectors. |
| semantic_search | Cosine ranking over indexed SchemaTable embeddings. Requires pretensor[embeddings]; returns a structured BM25-fallback envelope when the extra is absent or no tables have been embedded. |
| cypher | Read-only Kuzu Cypher for one indexed database; mutating clauses are rejected. |
| context | Full context for one physical table, including columns, joins, lineage, and cluster metadata. Optional include_similar arg surfaces cross-cluster nearest neighbors when embeddings are present. |
| traverse | Join paths between two physical tables. When ambiguous and tables carry embeddings, ranks tied paths by embedding similarity. |
| impact | Downstream tables reachable from a table via FK and inferred-join edges. |
| detect_changes | Compare the live database schema to the last indexed snapshot without mutating the graph. |
| compile_metric | Compile semantic-layer YAML into validated SQL for one indexed database. The error string includes a "did you mean: …" suggestion list when an unresolved metric, table, or column name has close matches. |
| validate_sql | Validate SQL against the indexed graph before execution. |
