LangChain has partnered with Arcade.dev to integrate Arcade's library of 7,500+ agent-optimized tools into LangSmith Fleet. Arcade acts as an MCP gateway, giving agents a single secure endpoint to connect to tools like Salesforce, Asana, Zendesk, and Slack. Unlike typical MCP servers that wrap REST APIs, Arcade's tools are purpose-built for agents with narrowed surfaces, consistent patterns, and LLM-friendly descriptions. The integration also handles per-user, session-scoped authorization with least-privilege enforcement, supporting both individual user credentials and shared service credentials. Over 60 pre-built Fleet templates are available to get started quickly.
