@us-all/dbt-mcp

dbt MCP server — manifest.json, run_results.json, sources.json, catalog.json, plus DQ result tables (BigQuery / Postgres) behind one stdio MCP. Built on @us-all/mcp-toolkit.

A read-only window into your dbt project for LLM clients. No dbt run triggering — just deep introspection, run-history analysis, source freshness, per-column test coverage, lineage walks, and (if you have a custom DQ result table) historical check trends and Tier SLA status.

For DAG triggering / run history / log tails, install the companion @us-all/airflow-mcp alongside.

• 22 tools across 3 categories (dbt, quality, meta)

• 4 MCP Prompts for triage workflows

• 4 aggregation tools that replace 3-5 round-trips of "list / get / list"

• Read-only by default

• Hybrid backend: BigQuery (default) or Postgres for DQ result tables — both peer-imported lazily

Install

# 1. add the MCP server
pnpm add -D @us-all/dbt-mcp
# 2. add the DQ backend you actually use (only if you query custom DQ tables):
pnpm add -D @google-cloud/bigquery   # OR
pnpm add -D pg

Run

DBT_PROJECT_DIR=/path/to/dbt-project \
DQ_RESULTS_TABLE=my-project.data_ops.quality_checks \
npx @us-all/dbt-mcp

The server speaks MCP stdio; wire it into Claude Desktop / Cursor / any MCP client. Set MCP_TRANSPORT=http to opt in to Streamable HTTP transport (Bearer auth, /health endpoint).

Categories

Toggle with DBT_TOOLS=dbt (allowlist) or DBT_DISABLE=quality (denylist).

Environment variables

DQ result-table assumed schema (v0.1)

The quality category assumes columns check_name, check_type, dataset, table_name, status, severity, failure_count, run_at, message on DQ_RESULTS_TABLE, and score_date, scope, tier, completeness_pct, freshness_pct, validity_pct, anomaly_free_pct, overall_score on DQ_SCORE_TABLE. v0.2 will add a configurable column-mapping layer.

Tested-against schemas

• dbt manifest schema v11 / v12 / v13 (others usually parse but a caveats line will flag them)

Companion server

For Airflow DAG operations (list, runs, task instances, log tail, trigger, clear), install @us-all/airflow-mcp alongside this server.

Build

pnpm install
pnpm run build      # tsc → dist/
pnpm test           # vitest
pnpm run smoke      # spawns dist/index.js, calls initialize + tools/list (set env first)
