bargo-congress

Bargo hosts a focused Streamable HTTP MCP server for the Congress Trades dataset at https://www.bargo.ai/free-apis/congress/mcp, exposing exactly three narrowly scoped read-only tools. The tool list below was captured live and verbatim from an anonymous JSON-RPC tools/list call (saved to bargo-congress-trades-api-tools-list.json) — handshake and tools/list are open, while tool CALLS require a free fak_ API key passed as X-Api-Key, as an Authorization Bearer header, or as a ?token= query parameter for connector UIs that cannot set headers. Every tool declares execution.taskSupport = forbidden, i.e. synchronous calls only, no long-running agent tasks.

Connect

This is a remote MCP server — point an MCP client at the endpoint URL. Clients with native remote support (Claude, Cursor, VS Code, …):

# mcp client config (e.g. .mcp.json / mcp settings) { "mcpServers": { "bargo-congress-trades-api": { "url": "https://www.bargo.ai/free-apis/congress/mcp" } } }

For stdio-only clients (older Claude Desktop, etc.), bridge with mcp-remote:

# Add to claude_desktop_config.json { "mcpServers": { "bargo-congress-trades-api": { "command": "npx", "args": ["-y", "mcp-remote", "https://www.bargo.ai/free-apis/congress/mcp"] } } }

If the server requires authentication, add the provider's token/header (e.g. an X-API-Key) per its docs. A quick reachability check:

curl -i -X POST https://www.bargo.ai/free-apis/congress/mcp \ -H "Content-Type: application/json" -H "Accept: application/json, text/event-stream" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Tools

get_congress_trades — U.S. Congress stock trades from official STOCK Act Periodic Transaction Reports (House Clerk + Senate eFD). Filter by ticker, member (substring), chamber, or type. Newest transaction first.
get_congress_member — All disclosed trades for one member of Congress plus a performance summary (trade count, buys/sells, average per-share return on disclosed buys).
get_congress_stats — Aggregate Congress-trading stats: total trades/members/tickers, buy vs sell counts, latest transaction & disclosure dates, and the most-traded tickers over the last 90 days.

About MCP

The Model Context Protocol (MCP) is an open protocol Anthropic introduced for connecting LLM-based agents to external tools and data sources. Providers publish MCP servers that expose their API surface as structured, discoverable tools — an MCP-compatible client (Claude Desktop, Cursor, Cline, Continue, etc.) can connect to the server and call its tools without any per-provider integration code.
