(1) A REMOTE documentation server at https://developers.sinch.com/mcp, announced by the developer portal agent card and reachable anonymously: it exposes two meta-tools (describe-tools, execute) that run JavaScript against documentation tools (API discovery, endpoint details, security schemes, full-text search) — it reads the docs, it does not call the Sinch APIs. (2) A LOCAL stdio server, @sinch/mcp on npm (developer preview, 0.0.1-alpha.6, 2026-04-14; source github.com/sinch/sinch-mcp-server), whose 25 documented tools send messages, emails, verifications and calls and manage numbers against the live Sinch and Mailgun APIs with the user''s own credentials.' deployment: mode: both endpoint: https://developers.sinch.com/mcp install: npx -y @sinch/mcp package: https://www.npmjs.com/package/@sinch/mcp auth: none verified: probed note: endpoint auth is none (anonymous initialize/tools/list returned 200); the local server needs PROJECT_ID + access key, APPLICATION_KEY/secret and MAILGUN_API_KEY env vars per its README. GET on the endpoint returns 405 with the instruction to register the URL in an MCP client.
