Power Players

Power Players MCP connectors

Power Players (powerplayers.app) is a civic platform where people rate US officials and candidates, track their ballot, contact their representatives and give to campaigns. These Model Context Protocol (MCP) connectors bring it into AI assistants such as Claude, ChatGPT, Grok, Perplexity and Le Chat.

The servers are hosted by Power Players. This repository holds the public listing material only: this README, the MCP Registry entry (server.json), the logo and the license. The server code is not published here.

Endpoints

All three use Streamable HTTP.

Connector	URL	Sign-in	What it does
Public civic data	https://powerplayers.app/api/mcp/v1	None	Ten read-only tools: search people, citizen ratings, trends, comparisons, voter-registration links, quote, embed and share helpers.
Your account	https://powerplayers.app/api/mcp/account	OAuth 2.1 (Clerk, PKCE, dynamic client registration)	Acts for a signed-in user: rate people, manage a ballot, email officials, Power stakes and boosts, donor-profile prep. Every write shows a preview and waits for the user's confirmation.
Power Players for Offices	https://powerplayers.app/api/mcp/office	OAuth 2.1, same sign-in	For officials, campaign managers and staff their office granted access: constituent sentiment, review replies, updates, town halls, AMA answers, staff access.

OAuth clients discover the authorization server from the protected-resource metadata:

• https://powerplayers.app/.well-known/oauth-protected-resource/api/mcp/account
• https://powerplayers.app/.well-known/oauth-protected-resource/api/mcp/office

Other discovery files: https://powerplayers.app/.well-known/mcp.json, https://powerplayers.app/.well-known/mcp/server.json and https://powerplayers.app/llms.txt.

Connect

• Claude: Settings > Connectors > Add custom connector, then paste a URL above.
• ChatGPT: Settings > Apps & Connectors (developer mode) > Create, then paste a URL above.
• Grok, Perplexity, Le Chat and other MCP clients: add a custom remote MCP server with a URL above.
• Claude Code: claude mcp add --transport http powerplayers https://powerplayers.app/api/mcp/v1

For the account and office connectors, the assistant opens a sign-in page; after signing in, call link_account and open the one-time link (valid 10 minutes) to connect the assistant to your Power Players account.

Giving to campaigns

Power Players makes donating to campaigns as easy as possible. The connectors never take a payment: an assistant can show who represents you and prepare the FEC donor details a contribution needs, and you check, certify and give on powerplayers.app.

Ratings are not polls

Citizen ratings are voluntary, crowdsourced opinions. They are not polls and are not statistically representative. Every rating response includes its sample count and source date.
