Team Access to Congressional Roster via MCP Server

When you commit the `.vscode/mcp.json` config, every developer on the team gets access to `list_congress_members`. This means everyone writes against a single source of truth for US Congress personnel data. It's great for standardizing reports that rely on knowing committee assignments or service dates across the board.

Standardize Bill and Treaty Lookup

The team can use `get_bill_details` to pull comprehensive information about any legislative bill. This ensures every developer, regardless of expertise, has access to accurate data. Need a full history? The `list_congress_treaties` tool pulls records for treaties handled by Congress, making them available in the team's shared context.

Manage Congressional Structure and Sessions

The `list_congress_sessions` tool lets your whole team accurately define legislative periods. You just specify a range or Congress number to get start/end dates. If you're building an archival tool, the ability to list historical congressional sessions is mandatory for consistent data handling.
