Share Alation catalog context in VS Code Copilot

Team-wide configuration files let every developer access the same Alation catalog metadata inside VS Code Copilot. Your VS Code Copilot agent runs `list_data_sources` to show everyone on the team exactly which Alation databases are verified for production use. This shared VS Code Copilot context prevents developers from querying stale or deprecated Alation databases. The VS Code Copilot agent runs `list_schemas` to ensure everyone writes queries against the current Alation source of truth.

Audit Alation governance fields in VS Code Copilot

Keep your VS Code Copilot code compliant with corporate data policies without leaving your workspace. VS Code Copilot uses the MCP Server tool `list_custom_fields` to pull down Alation data classification levels and ownership details. Before committing code in VS Code Copilot that touches sensitive columns, your agent runs `get_object_metadata` to verify Alation compliance tags. You catch Alation security violations inside VS Code Copilot before they hit your CI/CD pipeline.

Map Alation pipeline dependencies using this MCP Server

Prevent breaking changes in shared Alation data environments using VS Code Copilot. Your VS Code Copilot agent uses `get_lineage` to inspect how your Alation database tables connect to upstream ETL jobs. By combining this with `list_tables`, the VS Code Copilot editor maps out entire Alation data pipelines. You see exactly which teams rely on your Alation table before you push updates inside VS Code Copilot.
