Get detailed information about a candidate
AI agents call get_candidate 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 a public database (OpenFEC/FEC data) without modifying any data, executing code, deleting records, or moving money. It is a straightforward read-only query operation. The data is publicly available and intended for transparency purposes. The blast radius of misuse is minimal since no actions can be taken beyond accessing already-public information.
From the tool's definition Tool name 'get_candidate' and description 'Get detailed information about a candidate' indicate data retrieval with no modification or side effects. The OpenFEC API provides public Federal Election Commission campaign finance data.
