The libdatachannel MCP server covers libdatachannel, a standalone C++ implementation of WebRTC Data Channels and media transport. Each version is a release tag (e.g. v0.24.5). Its dependencies are git submodules (usrsctp, libjuice, plog…) that are not fetched, so only its own C++ source (src/ + the public API under include/rtc) is indexed. Shares this site's OAuth credentials — connect your MCP client at https://webrtc.page/libdatachannel.

HTTP transport with OAuth 2.1 (PKCE). Dynamic client registration is not supported — register a client first, then pass its client_id (and secret) in your MCP client config. Localhost redirect URIs are allowed for any port.

One registered client works for every server on this site — just point the URL at /libdatachannel.

1. Register a client and grab client_id / client_secret at /profile →

2. Configure your client with those credentials (examples below).
