Search for candidates by name or other criteria
AI agents call search_candidates to retrieve information from MCP OpenFEC Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves candidate information from the Federal Election Commission's public database via the OpenFEC API. The action is purely informational—searching and returning data without creating, modifying, deleting, or executing any operations. Public election data is inherently non-sensitive from a security perspective, and misuse would only result in information access, not financial harm or data loss.
From the tool's definition Tool name 'search_candidates' and description 'Search for candidates by name or other criteria' indicate a query/retrieval operation with no modification or deletion of data.
Attacks that exploit this kind of access
Search for candidates by name or other criteria. It is categorised as a Read tool in the MCP OpenFEC Server MCP Server, which means it retrieves data without modifying state.
Register the MCP OpenFEC Server MCP server in PolicyLayer and add a rule for search_candidates: 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 OpenFEC Server. Nothing to install.
search_candidates 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_candidates 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_candidates. 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_candidates is provided by the MCP OpenFEC Server MCP server (psalzman/mcp-openfec). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
