GSA CALC+

Connects Claude to GSA CALC+, the General Services Administration's database of awarded labor rates from Multiple Award Schedule contracts. Exposes 8 tools that query 230,000+ ceiling rates by labor category, contract vehicle, SIN, and awarded price. Useful when you're building an IGCE for a services contract and need real-world benchmarks instead of starting from scratch with market wages. Part of a larger federal contracting toolkit that includes regulatory lookups, spending data, and wage surveys. No API key required. Built by a contracting officer, so the schema matches how 1102s actually search for comparable rates during pre-award analysis.
