[Repo] modelcontextprotocol/experimental-ext-tasks: Status: Experimental. This repository provides a reference for the tasks extensions to the MCP protocol, allowing for long-running operations, such as Agent communication, in MCP.

The experimental-ext-tasks repository provides a reference implementation for task extensions to the Model Context Protocol (MCP), enabling long-running operations and agent communication. This experimental project extends MCP's capabilities to handle asynchronous, stateful operations beyond simple request-response patterns. It serves as a foundation for building agents that can manage complex, multi-step workflows within the MCP ecosystem.

Key Points

• •MCP protocol extension for long-running task operations and asynchronous workflows
• •Enables agent communication patterns within the Model Context Protocol framework
• •Experimental status indicates ongoing development and potential API changes
• •Reference implementation for developers building task-based agent systems
• •Supports stateful operations that extend beyond traditional request-response interactions
• •Provides foundation for complex multi-step agent workflows and orchestration
• •Allows agents to manage and track long-duration operations in MCP environments
