Servers

RingCentral currently publishes four active MCP servers. All implement the Model Context Protocol specification and are reachable over HTTPS using Server-Sent Events (SSE) transport.

Transport & protocol

Both servers use SSE (Server-Sent Events) transport over HTTPS, which is the recommended transport for remote MCP servers. Clients connect by sending an HTTP POST to the server URL with a JSON-RPC 2.0 body.

# Discover tools on any server
curl -X POST https://<server-url> \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}'

Authentication model

  • RingEx Phone / Chat / Admin — no authentication required for tool discovery; most tools require a valid RingCentral session.
  • App Connect — tools marked ⚠️ REQUIRES CRM CONNECTION require the user to have authenticated with both RingCentral and a supported CRM platform.

Versioning policy

Labs servers follow a rolling-release model. Breaking changes will be announced in the Changelog with at least 14 days notice. Stable tools are versioned via api-version query parameter where applicable.
