GSA CALC+

Overview

GSA CALC+ is a Model Context Protocol (MCP) server: GSA CALC+ awarded labor ceiling rates from more than 230,000 MAS contract records. 8 tools. In practice that means any MCP-compatible AI assistant can call GSA CALC+'s tools directly — the model decides when to use them in a conversation or agent run.

It runs locally: the Python package gsa-calc-mcp (via uvx) speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v1.0.5, published under the MIT license, with source at 1102tools-dev/federal-contracting-mcps on GitHub, where it has earned 20 stars.

GSA CALC+ is listed under Development on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
