Connect the MCP server

The Quiver MCP server lets AI assistants query Quiver data directly: ask “What stocks have members of Congress bought in the last 30 days?” and the assistant calls Quiver’s tools to answer. It’s a remote server, so there’s nothing to install.


Server URL	`https://mcp.quiverquant.com/`
Transport	Streamable HTTP
Sign-in	OAuth at `auth.quiverquant.com` (email code or Google), or your API key as a Bearer token
Plan	Any Quiver API plan. See Plans and data access.

When you sign in with OAuth, use the same email address as your Quiver API account. If you sign in with a different email, the tools respond “authenticated but has no active subscription” even though you’ve paid.

How do I connect my AI assistant?

In Claude, open Customize in the sidebar, then Connectors.
Search for Quiver Quant, click +, then Connect.
Sign in with the email on your Quiver API account and click Approve.

You can also add it as a custom connector: choose Add custom connector, enter https://mcp.quiverquant.com/ and leave the OAuth client ID and secret blank.This works on claude.ai and in Claude Desktop. On Claude Team and Enterprise plans, an owner can add the connector once for the whole organization; each member then connects with their own Quiver account and plan.See the step-by-step guides for Claude in the browser and Claude Desktop.

In ChatGPT, open Settings and turn on developer mode.
Add a connector and paste the server URL: https://mcp.quiverquant.com/
Sign in with the email on your Quiver API account and click Allow.

See the ChatGPT setup guide for screenshots of each step.

claude mcp add --transport http quiverquant https://mcp.quiverquant.com/

Then run /mcp in Claude Code and choose quiverquant to sign in. To use your API key instead of signing in:

claude mcp add --transport http quiverquant https://mcp.quiverquant.com/ \
  --header "Authorization: Bearer YOUR_API_KEY"

Add the server to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "quiverquant": {
      "url": "https://mcp.quiverquant.com/"
    }
  }
}

Cursor opens a sign-in page the first time it connects. To use your API key instead, add "headers": {"Authorization": "Bearer YOUR_API_KEY"} next to url.

Run MCP: Add Server from the Command Palette, choose HTTP and enter https://mcp.quiverquant.com/. Or add it to .vscode/mcp.json:

{
  "servers": {
    "quiverquant": {
      "type": "http",
      "url": "https://mcp.quiverquant.com/"
    }
  }
}

To use your API key instead of signing in, add "headers": {"Authorization": "Bearer YOUR_API_KEY"} next to url.

Any client that supports remote MCP servers over streamable HTTP can connect to https://mcp.quiverquant.com/. For clients that only run local servers, use mcp-remote as a bridge:

{
  "mcpServers": {
    "quiverquant": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.quiverquant.com/",
        "--header",
        "Authorization:${AUTH_HEADER}"
      ],
      "env": {
        "AUTH_HEADER": "Bearer YOUR_API_KEY"
      }
    }
  }
}

To sign in with OAuth instead, drop --header and the env block. mcp-remote opens a browser window to sign in the first time.

Don’t put your API key in the request headers of a connector shared across a Claude Team or Enterprise organization. Those headers are shared with everyone who uses the connector, so they’d all use your account. Shared connectors should use OAuth sign-in.

Which tools does the server provide?

Tool	What it does
`get_congress_trades`	Get stock transactions by members of the U.S. Congress.
`get_congress_politician`	Get detailed information about a U.S. Congress member including their profile, net worth, stock portfolio, top donors, and recent trading activity.
`get_congress_legislation`	Get bills, legislation, and AI-generated bill summaries from Congress.
`get_insider_trading`	Get SEC Form 4 insider trading transactions.
`get_institutional_holdings`	Get SEC 13F institutional holdings data.
`get_gov_contracts`	Get government contracts and awards by ticker symbol.
`get_lobbying`	Get corporate lobbying spending data.
`get_ticker_ownership`	Get ownership data for a stock: insider holdings, institutional holders (13F), ownership breakdown, and executive compensation.
`get_dark_pool`	Get off-exchange (dark pool) trading data for a stock.
`get_patents`	Get patent filing data for a company including patent count, filing trends (drift), and momentum metrics.
`get_political_exposure`	Get a comprehensive political exposure report for a stock ticker.
`get_ticker_full_picture`	Get a combined picture of a stock: ownership breakdown (insider sentiment, 13F summary, top owners) and recent insider trading in one response.
`compare_tickers`	Compare 2-3 stock tickers side by side across any available dataset (congress trades, insider trading, ownership, social sentiment, etc.).
`search_datasets`	Discover what data is available in QuiverQuant.
`query_quiver_api`	Direct access to any QuiverQuant API endpoint by name.
`get_corporate_donors`	Get corporate PAC donation history from FEC filings.
`get_executive_compensation`	Get SEC executive compensation disclosures from proxy filings.
`get_quiver_newsfeed`	Get curated news from the Quiver newsfeed.
`get_trump_trades`	Get stock transactions by U.S. President Donald Trump (STOCK Act disclosures).

search_datasets works without a plan. Every other tool needs an active Quiver API plan, and returns a message saying so if your account doesn’t have one.

What should I ask?

“What stocks have members of Congress traded in the last 30 days?”
“Show me recent insider transactions for NVDA.”
“Show me lobbying spending by Lockheed Martin this year.”
“Give me the full picture on NVDA: ownership, insider activity and political exposure.”
“What datasets does Quiver offer?” This works before you subscribe.

Troubleshooting

"Your QuiverQuant account is authenticated but has no active subscription"

You’re signed in, but the account you signed in with has no active Quiver API plan. Common causes:

You signed in with a different email from the one on your API account, often because your browser reused an earlier sign-in. Disconnect the server, open the sign-in in a private window, and sign in with the email on your API account.
Your subscription is to the Quiver website (a Quiver Platform plan). That’s a separate product: the MCP data tools need a Quiver API plan from the pricing page.

"Protected resource does not match"

The server URL must be exactly https://mcp.quiverquant.com/: the hostname with a trailing slash, with no /mcp path.

A tool says to upgrade your plan

Your plan doesn’t include that tool’s data. See Plans and data access.
