What it does
This server exposes GSA CALC+ awarded labor ceiling rates from 230,000+ GSA Multiple Award Schedule (MAS) contracts. It is for federal contractors, government buyers, and procurement professionals who need to query current labor rates for specific occupations and contract vehicles.
- Look up prevailing wage rates for labor categories across GSA schedules to inform independent government cost estimates (IGCEs).
- Compare labor ceiling rates across different contract vehicles and vendors for a specific occupation code.
- Verify that proposed labor rates fall within GSA CALC+ benchmarks for compliance with federal contracting requirements.
Tools this server exposes
| Tool | Does |
|---|---|
| gsa_calc_search | Query GSA CALC+ labor rates by occupation, contract vehicle, or other contract parameters. |
| gsa_calc_get_rates | Retrieve specific awarded labor ceiling rates from GSA MAS contracts. |
| get_access_status | Check whether required credentials are present for GSA CALC+ queries. |
This entry comes from the registry but points to no public repository, so there is nothing to check: no commit history, no source, no tool list. It is listed for completeness and left out of search engines.
Before you enable it
An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
