Search for individual donors across all FEC filings by name, employer, or occupation. Essential for tracking donor patterns, identifying industry contributions, or researching specific individuals
AI agents call search_donors to retrieve information from Fec 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 FEC campaign finance data about donors. The verbs used (search, tracking, identifying, researching) indicate read-only operations that retrieve information without side effects. While donor information may be sensitive, it is public FEC data, and the tool has no capability to modify, delete, or execute operations.
From the tool's definition Tool description states 'Search for individual donors' and explicitly lists read-only operations: 'tracking donor patterns, identifying industry contributions, or researching specific individuals.' These are query and analysis operations with no modification…

Search for individual donors across all FEC filings by name, employer, or occupation. Essential for tracking donor patterns, identifying industry contributions, or researching specific individuals. It is categorised as a Read tool in the Fec MCP Server, which means it retrieves data without modifying state.
Register the Fec MCP server in PolicyLayer and add a rule for search_donors: 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 Fec. Nothing to install.
search_donors 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 search_donors 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 search_donors. 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.
search_donors is provided by the Fec MCP server (sh-patterson/fec-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
