What is the LangGraph Cloud (Stateful AI Agents) MCP Server?
Connect your LangGraph Cloud account to any AI agent and take full control of your stateful multi-turn agents and complex graph-based AI workflows through natural conversation.
What you can do
- Assistant Orchestration — List deployed assistants representing compiled LangGraph applications ready to process stateful workloads directly from your agent
- Thread Management — Create and monitor conversation threads to maintain long-term memory buffers explicitly managed by cloud checkpoints
- State Inspection & Override — Retrieve the exact execution state of a thread and perform manual node overrides for human-in-the-loop approvals or mid-execution adjustments
- Run Control — Trigger fresh graph executions with specific input payloads and monitor or cancel asynchronous runs to manage system resources
- Cron Automation Audit — List scheduled background jobs configured to autonomously trigger LangGraph execution runs periodically
- History Tracking — Extract historical run steps indicating explicit graph invocations and internal reasoning paths within a stateful thread
How it works
- Subscribe to this server
- Enter your LangGraph API URL and API Key
- Start managing your agentic infrastructure from Claude, Cursor, or any MCP-compatible client
Who is this for?
- AI Agentic Developers — debug stateful multi-turn agents and verify graph traversal paths through natural conversation
- AI Platform Engineers — monitor deployed assistants and manage cloud-based checkpoints across multiple team environments
- Ops Teams — audit scheduled crons and manage execution runs to ensure reliable delivery of automated AI workflows
Built-in capabilities (10)
Interrupt and cancel an ongoing graph execution run
Execute an assistant run on a specific thread with an input payload
Create a new LangGraph thread to hold conversational state
Get complete details and status of a specific language graph run
g., current messages array or structured outputs) generated by the LangGraph application. Retrieve the exact state graph and variables for a specific thread
List LangGraph deployed assistants (graph configurations)
List active scheduled cron jobs automating agent runs
List execution runs assigned to a specific thread
List active LangGraph conversation threads
Manually override or update a thread state graph
Why Mastra AI?
Mastra's agent abstraction provides a clean separation between LLM logic and LangGraph Cloud (Stateful AI Agents) tool infrastructure. Connect 10 tools through Vinkius and use Mastra's built-in workflow engine to chain tool calls with conditional logic, retries, and parallel execution. deployable to any Node.js host in one command.

Frequently asked questions
Can I manually approve an agent's step using this server?
Yes. Use the update_thread_state tool to perform manual node state overrides. This is the standard way to implement human-in-the-loop (HITL) patterns, allowing you to modify or approve graph variables directly mid-execution.
How do I see the current memory of a conversation thread?
The get_thread_state tool retrieves the exact execution state of a thread, including all cyclical node variables and structured outputs stored in the cloud checkpoints. This gives your agent full visibility into the conversation history.
Can my agent trigger a new run on an existing thread?
Absolutely. Use the create_run tool and provide the Thread ID, Assistant ID, and your new input payload. Your agent will fire the graph dynamically, allowing for multi-turn engagements within the same stateful boundary.
How does Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
