AI agents call gov.exclusions to retrieve information from Mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries publicly available exclusion data from a government database. It performs no modifications, deletions, code execution, or financial operations. The search capability (by name, ueiSAM, cageCode, classificationType) is a straightforward lookup function.

Check whether a person or company is excluded (debarred/suspended) from US federal contracts, grants, or assistance — the SAM.gov Exclusions list. Search by name, ueiSAM, cageCode, classificationType. Returns each exclusion with classification, type, program, excluding agency, dates, and address. Free, public-domain. Distinct from law.sanctions-check (OFAC). It is categorised as a Read tool in the Mcp MCP Server, which means it retrieves data without modifying state.
Register the MCP server in PolicyLayer and add a rule for gov.exclusions: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mcp. Nothing to install.
gov.exclusions is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the gov.exclusions rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for gov.exclusions. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
gov.exclusions is provided by the MCP server (@2sio/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
