The Bitly MCP Server brings the full power of Bitly’s link management platform to AI agents operating within Caylex, enabling them to create and customize short URLs, generate QR Codes, and analyze link performance through natural language commands. This server exposes the same capabilities available in the Bitly web interface and API, making it possible for agents to automate marketing workflows, content sharing, and campaign tracking without manual intervention. Bitly uses HTTP/Streamable HTTP transport, meaning no local installation is required — the server is cloud-hosted and ready to connect as soon as authentication is configured in your Caylex project. Authentication is supported via OAuth 2.1 (recommended for secure, token-based access) or a Bitly API token supplied as a Bearer header. Once connected, AI agents can manage links, track click analytics, and handle branded short domains entirely through tool invocations.
Prerequisites:
  • A Bitly account is required; for API token authentication, generate a token at https://bitly.com/settings/api before adding the server in Caylex.
  • For OAuth 2.1 authentication, your Bitly account must support OAuth with Dynamic Client Registration (available on supported Bitly plans).
Important API details:
  • Authentication can be configured using either OAuth 2.1 (recommended) or a static Bitly API token passed as a Bearer token in the Authorization header.
  • The server uses HTTP/Streamable HTTP transport — it is fully remote and cloud-hosted, requiring no local installation or proxy setup.
  • OAuth 2.1 supports Dynamic Client Registration, allowing Caylex to register automatically without manual app creation in the Bitly developer portal.
  • API token access requires generating a personal API token from your Bitly account settings before connecting in Caylex.
