search_contributions
AI agents call search_contributions to retrieve information from FEC Campaign Finance MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries publicly available US federal campaign finance contribution data. It has no side effects, creates no modifications, executes no code, and cannot delete or move money. While the tool description is empty (lowering confidence slightly from 0.95), the name and server context strongly indicate read-only data access to FEC public records.
From the tool's definition Tool name 'search_contributions' combined with server context (OpenFEC API for campaign finance investigation) and sibling tools (get_campaign_expenditures, get_contributions_by_state, get_top_donors, search_candidates, search_pacs) indicate data retrieval.
