The MCP server is a developer preview whose npm release dates from 2026-04-14.\n\n**Telegram Bot API.** Telegram's first-party bot interface is free, needs no card and documents 185 methods on one page with a dated changelog and numeric send limits. No OpenAPI document, status page, SLA or idempotency key was found, one token controls the whole bot and travels in the URL, and a person must create the bot in a chat with @BotFather.\n\n## Before you call either\n\n### Sinch Messaging APIs + MCP\n\n1. Load the MCP with `--tags` for the channels you need, or all 54 tools land in context\n2. Keep a single-tenant HTTP MCP bound to localhost, it does no inbound authentication\n3. Expect sends to drain at 20 messages a second per app unless Sinch raises it\n4. Verify `x-sinch-webhook-signature` against the raw body before parsing the JSON\n5. Use the regional base URL (us, eu or br) that matches the project\n\n### Telegram Bot API\n\n1. Send `POST https://api.telegram.org/bot\u003ctoken\u003e/sendMessage` with `chat_id` and `text`. Keep the token out of logs, because it is part of the URL.\n2. On HTTP 429 wait the `parameters.retry_after` seconds before retrying. Stay under one message a second per chat and 20 a minute per group.\n3. Call `getUpdates` with `offset` set to the last `update_id` plus one, or the same updates return. Updates are kept for at most 24 hours.\n4. A retried send can post twice, as there is no idempotency key. Record the returned `message_id` before retrying after a timeout.\n5. In groups the bot sees only commands and replies unless privacy mode is disabled in @BotFather or the bot is an admin.\n\n## Questions\n\n### Which is better for AI agents, Sinch Messaging APIs + MCP or Telegram Bot API?\n\nSinch Messaging APIs + MCP scores 63.2 (B) on agent readiness against Telegram Bot API's 43 (E), and leads in 6 of 7 scored categories.\n\n### Do Sinch Messaging APIs + MCP and Telegram Bot API need an API key?\n\nSinch Messaging APIs + MCP takes an API key or an OAuth sign-in.
