Quiver MCP Setup with Claude Desktop

Quiver hosts a remote MCP server that gives Claude Desktop access to data on congressional trading activity, government contracts, lobbying spend, patents, SEC filings, dark pool activity, and multi-dataset company analysis. Follow the steps below to get connected. We’ll be using Claude Desktop for this example, but it’s pretty easy to connect to most other major LLMs in a similar fashion.

Step 1: Download Claude Desktop

You'll need the Claude Desktop app. If you don't have it yet, download it from claude.ai/download and create a free Anthropic account.

Step 2: Connect to the Quiver MCP Server

You'll also need an API key. If you don't have one, you'll need to get one from Quiver API.

Once you have Claude Desktop installed, open it and navigate to the Customize section in the left sidebar. From there, select Connectors and search for Quiver Quant in the search bar.

Click the plus button, then click Connect to Claude

A browser window will open. Sign in at the QuiverQuant login page with the same email associated with your QuiverQuant API account and hit Approve. Ensure the account has an active API subscription.

Step 3: View Available Tools

Once connected, you can explore what's available by opening Claude Desktop and selecting Customize from the left sidebar, then navigating to Connectors, then Connected. You'll see the QuiverQuant MCP listed there, and when you click on it, you'll see all the tools it provides.

Tools are the specific capabilities Claude gains through the MCP server. When you ask Claude a question, it automatically draws on the relevant tools to inform its answer.

Step 4: Ask Claude a Question

Now that the server is connected, try asking things like "What stocks have members of Congress traded in the last 30 days?", "Show me recent insider transactions for NVDA", or "Which companies are the biggest lobbying spenders right now?" Claude will automatically use the connected tools when they're relevant to your request, and you can see which tools it's using as it works.

Alternative: Old Setup Method

Open claude_desktop_config.json (located at ~/Library/Application Support/Claude/ on Mac, or %APPDATA%\Claude\ on Windows) and add the following inside the "mcpServers" block.


          {
            "mcpServers": {
              "quiverquant": {
                "command": "npx",
                "args": ["-y", "mcp-remote@latest", "https://mcp.quiverquant.com/"]
              }
            }
          }

You can also find the file you need to edit by navigating to Claude's developer settings. After saving the file, restart Claude Desktop. It will launch a window for you to log in.
