Description

Two packages: @twilio-alpha/mcp, an MCP server for all of Twilio's public API, and openapi-mcp-server, which serves any OpenAPI spec as MCP tools. Because the full API is large, filter with --services and --tags to fit model context. Twilio advises not running community MCP servers alongside the official one to limit injection risk. Experimental (Twilio Alpha).
