Self-contained database platform — query engine, REST API, MCP server, and React admin console — shipped as a single Rust binary. One process, no external dependencies, deploys anywhere.

• Query any database from one place — connect SQL Server, PostgreSQL, and DuckDB by name. Run queries through the REST API, MCP server, or web UI.
• Turn queries into APIs — save SQL as named endpoints with {{parameters}}. Consumers call by name, no SQL needed.
• Cross-database analysis — export query results to S3/MinIO, import into the DuckDB workspace, join data across databases, export results back to storage as CSV, JSON, or Parquet.
• Give AI agents safe database access — 33 MCP tools with read/write separation, permission tiers, and approval workflows.
• Control access — four SQL permission tiers, per-table CRUD, per-connection restrictions, service accounts, PII detection/redaction, and teams.
• Stream changes — SSE on any table, no polling, no external broker.

The server starts on http://localhost:3401. Visit /setup to create your admin account.

Add database and storage connections through the admin API or web UI:

# Add a SQL Server connection
curl -X POST http://localhost:3401/api/lane/admin/connections \
  -H "Content-Type: application/json" \
  -H "x-lane-key: YOUR_API_KEY" \
  -d '{
    "name": "production",
    "type": "mssql",
    "host": "sql.example.com",
    "port": 1433,
    "database": "master",
    "username": "sa",
    "password": "secret"
  }'

# Add a PostgreSQL connection
curl -X POST http://localhost:3401/api/lane/admin/
