Congress Explorer Web

This plugin connects to the public Congress Explorer server at https://congress-explorer-mcp.mdeeb.workers.dev/mcp using Streamable HTTP. Authentication is None. It needs no local Python, Node.js, uv, or desktop app.

For ChatGPT web, open Plugins, choose Add custom MCP server, enter the URL, and select No authentication. Create and install the resulting plugin, then ask it to discover the available Congress data. See the official connection guide.

Use congress-explorer-web for hosted sessions and congress-explorer for local desktop sessions. The current plugin format specifies one transport per server; it does not define automatic browser/desktop selection. Installing both does not establish a preference. Select the appropriate plugin for the session.

Queries and results pass through the hosted service. The service uses a pinned public archive release; desktop clients may have selected another release. Always start with get_dataset_info. A cold service may take longer to respond. Local cache and prepare instructions apply only to the desktop plugin.

This directory is a portable plugin source. Its manifests, icons, license, and research skill are generated from the parent app by scripts/build_desktop.py. Edit the parent sources and regenerate; do not edit the generated copies. The build emits a separate congress-explorer-web-VERSION.plugin.zip containing only this hosted configuration and its instructions. Repository registration and ZIP generation do not install or publish a plugin in ChatGPT's directory.
