Install in Claude Cowork Desktop

Cowork is the desktop app's automation mode. To give it the Congress Trading API as a tool, add the Apify MCP server as a connector.

1. Open the Claude desktop app and go to Settings → Connectors (or Settings → Developer → Edit Config to edit claude_desktop_config.json directly). - macOS: ~/Library/Application Support/Claude/claude_desktop_config.json - Windows: %APPDATA%\Claude\claude_desktop_config.json 2. Add the Apify MCP server, preloaded with only this Actor:

{
  "mcpServers": {
    "apify": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.apify.com/?tools=actors,docs,johnvc/us-congress-financial-disclosures-and-stock-trading-data"
      ]
    }
  }
}

1. Restart the app. When Cowork first calls the tool, complete the OAuth prompt in your browser, or add your Apify API token in the connector settings to skip OAuth.
2. In a Cowork chat, confirm the tool is available and ask it to run the Congress Trading API.

Install in Claude Code

Claude Code is the command-line tool. Add the Actor's MCP server with one command:

claude mcp add --transport http apify \
  "https://mcp.apify.com/?tools=actors,docs,johnvc/us-congress-financial-disclosures-and-stock-trading-data"

To use a token instead of browser OAuth:

claude mcp add --transport http apify \
  "https://mcp.apify.com/?tools=actors,docs,johnvc/us-congress-financial-disclosures-and-stock-trading-data" \
  --header "Authorization: Bearer YOUR_APIFY_TOKEN"

Then verify with claude mcp list, or run /mcp inside a session. Ask Claude Code to call the Congress Trading API.

Install in Claude (website)

On claude.ai you add Apify as a connector, then enable just this Actor's tool.

1. Go to Settings → Connectors → Browse connectors and search for Apify MCP server. Install it (enable or update if prompted).
2. When connecting, authenticate with your Apify API token, and enable the tool johnvc/us-congress-financial-disclosures-and-stock-trading-data.
3. In any chat, open + → Connectors and turn on Apify.
4. Alternatively, choose Add custom connector and paste the full MCP URL https://mcp.apify.com/?tools=actors,docs,johnvc/us-congress-financial-disclosures-and-stock-trading-data, using OAuth when prompted.
5. Ask Claude to run the Congress Trading API.

Open Claude on the web: https://claude.ai

Install in Cursor

Cursor reads MCP servers from a project file at .cursor/mcp.json.

1. In your project, create .cursor/mcp.json:

{
  "mcpServers": {
    "apify": {
      "url": "https://mcp.apify.com/?tools=actors,docs,johnvc/us-congress-financial-disclosures-and-stock-trading-data"
    }
  }
}

1. If you prefer token auth over browser OAuth, add a header:

{
  "mcpServers": {
    "apify": {
      "url": "https://mcp.apify.com/?tools=actors,docs,johnvc/us-congress-financial-disclosures-and-stock-trading-data",
      "headers": { "Authorization": "Bearer YOUR_APIFY_TOKEN" }
    }
  }
}

1. Open Cursor → Settings → MCP and confirm the apify server is connected (green dot).
2. In Composer or Chat, ask Cursor to call the Congress Trading API.

Install in ChatGPT

ChatGPT connects to the Apify MCP server through Developer mode (available on ChatGPT Pro, Plus, Business, Enterprise, and Education plans).

1. Click your profile icon, then go to Settings > Apps. If you do not see a Create app button, open Advanced settings and enable Developer mode. 2. Click Create app and fill out the form: - Name: Apify - MCP Server URL: https://mcp.apify.com/?tools=actors,docs,johnvc/us-congress-financial-disclosures-and-stock-trading-data - Authentication: OAuth 3. Click Create and authorize the connection with Apify. 4. To use the app in a conversation, click + in the chat, choose Developer mode, and select Apify.

🏛️ Congress Trading API: US Congressional Stock Trades and Disclosures in Clean JSON

The most efficient, reliable, and developer-friendly way to use the Congress Trading API.

Actor page: apify.com/johnvc/us-congress-financial-disclosures-and-stock-trading-data Input schema: apify.com/johnvc/us-congress-financial-disclosures-and-stock-trading-data/input-schema

The Congress Trading API returns US Congressional Periodic Transaction Reports (PTRs) as clean, structured JSON. Each row is one disclosed transaction: the member name and chamber, state and district, asset and ticker, transaction type, reported amount range, transaction and notification dates, ownership, and filing IDs. Filter by member name, ticker, an exact date, or a date range. Data is normalized from official US House and Senate financial disclosure filings under the STOCK Act.

Why Use This Congress Trading API?

Both chambers, one schema. House and Senate Periodic Transaction Reports are normalized into a single, queryable shape, so you analyze all of Congress with one parser instead of two filing systems.

Powerful filters. Narrow by member first or last name, by stock ticker, by an exact transaction date, or by a date range. Combine them to answer questions like "every NVDA trade this member made in 2024."

Audit-ready structured JSON. One row per transaction, with the reported amount range exactly as filed, plus filing and document IDs and per-run search metadata for traceable, reproducible pulls.

Predictable, pay-per-use pricing. Billing is per run plus per transaction returned, with no monthly rental. You control cost directly with Max_Results.

Easy to automate. Call it from Python in a few lines, or load it as an MCP tool so assistants like Claude and Cursor can pull Congressional trades for you on demand.
