Reviewer Notes

Telegram offers a well-documented Bot API with clear REST endpoints and good reliability, making agent discovery moderate. However, account creation is problematic—agents cannot programmatically create user accounts due to phone verification requirements; bot creation requires manual registration. The Bot API tooling is reasonable but lacks structured OpenAPI specs and MCP servers. Free tier is generous but doesn't eliminate human friction for initial setup.
