MCP server
Federal contract data, inside your AI assistant

Coverage
Every figure comes from USAspending.gov prime contract awards, in obligated US dollars. Civilian agency awards are about 4 days fresh; Department of Defense awards are withheld about 90 days, so recent defense activity looks sparser than it is. Expiring contracts need SAM.gov access and are not live yet — the tool is listed so agents can see what is coming.
