Implements the Model Context Protocol (MCP) server specification, exposing tools and resources via the MCP standard interface using stdio-based bidirectional communication. The server handles JSON-RPC 2.0 message framing, capability negotiation during initialization, and maintains protocol state across client connections. This enables any MCP-compatible client (Claude Desktop, custom agents, LLM applications) to discover and invoke server capabilities through a standardized protocol rather than direct API calls.

Provides a framework for defining tools with JSON Schema specifications, parameter validation, and execution handlers. Tools are registered with the MCP server and exposed to clients with full schema metadata (name, description, input schema, required parameters). When a client invokes a tool, the framework validates inputs against the schema, executes the corresponding handler function, and returns structured results. This decouples tool definition from tool execution, enabling dynamic tool discovery and type-safe parameter passing.

Implements MCP resource protocol for exposing static or dynamic content (files, templates, documentation, configuration) to clients through a URI-based addressing scheme. Resources are registered with metadata (name, description, MIME type, URI) and can be read by clients without executing code. The framework handles resource discovery (listing available resources) and content retrieval (reading specific resource content), enabling clients to access shared context, templates, or reference materials without direct file system access.

Enables definition of reusable prompt templates with variable placeholders that can be discovered and instantiated by MCP clients. Templates are registered with metadata (name, description, arguments schema) and clients can request template content with specific argument values. This allows centralizing prompt engineering on the server side while enabling clients (like Claude) to dynamically use optimized prompts without hardcoding them. Templates support argument validation and can reference other resources or tools.

Implements MCP initialization handshake that exchanges server and client capabilities, enabling feature detection and graceful degradation. During initialization, the server declares supported capabilities (tools, resources, prompts, sampling) and the client declares its capabilities. This allows servers to adapt behavior based on client features and clients to discover what functionality is available before attempting to use it. The negotiation happens once per connection and informs all subsequent interactions.
