sage-mcp-protocol

The sage-mcp-protocol module provides a comprehensive, native Rust implementation of the Model Context Protocol (MCP) for the Sage agent. This skill empowers the agent to seamlessly interact with external MCP servers, effectively extending its capabilities beyond local file system and shell operations. It acts as a robust bridge between the agent's core execution engine and a growing ecosystem of tools, resources, and prompts, enabling dynamic integration of third-party services and specialized data sources.

• Full implementation of MCP lifecycle management including initialization, capability negotiation, and notification handling.

• Native support for multiple transport layers such as Stdio for local processes and HTTP for network-based tool servers.

• Integrated service discovery, health monitoring, and connection management for automated MCP server orchestration.

• Built-in Schema translation layer, ensuring interoperability between external tool definitions and the agent's internal tool execution environment.

• Advanced caching system for tools, resources, and prompts, minimizing latency during tool execution and metadata retrieval.

• Native JSON-RPC message handling, conforming to the 2024-11-05 MCP specification version.

• Ideal for developers and engineers building extensible AI agents who need to connect to custom data-fetching, API-querying, or specialized computing MCP servers.

• Input typically involves identifying and connecting to an MCP server endpoint (stdio path or URL), while the output is a set of usable tools, resources, and prompt templates ready for agent invocation.

• Practical usage includes automating the discovery of available resources, keeping caches updated via notification processors, and handling errors during asynchronous request cycles.

• Operates with strict adherence to JSON-RPC 2.0 standards, ensuring high compatibility with standard MCP-compliant servers.

• Constraints include reliance on stable connectivity to the underlying transport layer; network-based HTTP transports require proper configuration of base URLs and authentication credentials as supported by the specific server implementation.
