Implements the Model Context Protocol server-side runtime using JSON-RPC 2.0 message framing over stdio, WebSocket, or SSE transports. Handles request/response routing, error serialization, and protocol version negotiation through a transport-agnostic abstraction layer that maps incoming MCP messages to TypeScript handler functions.
Unique: Provides a TypeScript-native MCP server SDK with transport abstraction (stdio, WebSocket, SSE) built into the core library, avoiding the need for separate transport adapters. Implements full JSON-RPC 2.0 compliance with automatic error code mapping and protocol version negotiation.
vs alternatives: More complete than raw JSON-RPC libraries because it includes MCP-specific message routing and capability advertisement; lighter than full agent frameworks because it focuses solely on server-side protocol implementation without client logic or LLM integration.
Provides a declarative API for defining tool schemas (name, description, input parameters) that automatically transpile to OpenAI function-calling format and Anthropic tool_use format. Includes runtime validation of tool invocations against declared schemas using JSON Schema validation, with type-safe TypeScript interfaces generated from schema definitions.
Unique: Implements automatic schema transpilation to both OpenAI and Anthropic formats from a single MCP tool definition, with built-in JSON Schema validation and TypeScript type generation. Avoids manual format conversion and keeps tool definitions DRY across multiple LLM providers.
vs alternatives: More provider-agnostic than OpenAI's function-calling SDK or Anthropic's tool_use API because it abstracts over both formats; more complete than generic JSON Schema validators because it includes MCP-specific tool metadata (description, category) and automatic type generation.
Implements a resource registry that maps URIs (e.g., 'file://path/to/file', 'db://query/users') to content providers. Supports streaming large resources via chunked responses, automatic MIME type detection, and content-type negotiation. Handlers can return text, binary, or structured data with automatic serialization based on declared MIME types.
Unique: Implements URI-based resource routing with automatic MIME type negotiation and chunked streaming, allowing agents to reference external content without loading it into context. Supports dynamic content generation and lazy-loading of large resources.
vs alternatives: More flexible than static file serving because it supports dynamic content generation and database queries; more efficient than context-injection because it streams resources on-demand rather than loading everything upfront.
Provides a registry for storing reusable prompt templates with named placeholders that can be filled at runtime. Supports multi-turn conversation templates with role-based message sequencing (system, user, assistant). Templates are versioned and can reference other templates, enabling composition of complex prompts from simpler building blocks.
Unique: Implements a template registry with multi-turn conversation support and template composition, allowing prompts to be versioned and reused across multiple agents. Includes role-based message sequencing for consistent conversation structure.
vs alternatives: More structured than ad-hoc string formatting because it enforces template schemas and enables composition; lighter than full prompt management platforms because it focuses on template definition and rendering without optimization or analytics.
Implements a client-side MCP connection handler that manages the lifecycle of connections to MCP servers (stdio, WebSocket, SSE). Automatically handles reconnection with exponential backoff, multiplexes concurrent requests over a single connection, and maintains request/response correlation using JSON-RPC message IDs. Provides a Promise-based API for invoking remote tools and resources.
Unique: Implements automatic reconnection with exponential backoff and request multiplexing over a single MCP connection, abstracting away transport-level complexity. Provides a Promise-based API that hides JSON-RPC message ID correlation.
vs alternatives: More resilient than raw JSON-RPC clients because it includes automatic reconnection and exponential backoff; simpler than full agent frameworks because it focuses solely on connection management without LLM integration or tool orchestration.
Implements MCP protocol capability negotiation where servers advertise supported features (tools, resources, prompts) and clients discover available capabilities. Includes version negotiation to ensure client and server compatibility, with fallback mechanisms for older protocol versions. Capabilities are advertised as structured metadata (schemas, descriptions, URIs) that clients can inspect before invoking.
Unique: Implements structured capability advertisement with version negotiation, allowing clients to discover and validate server capabilities before invoking them. Includes fallback mechanisms for protocol version compatibility.
vs alternatives: More explicit than introspection-based discovery because capabilities are advertised upfront; more flexible than static capability lists because it supports version negotiation and dynamic discovery.
Implements comprehensive error handling that maps application errors to MCP-compliant error codes (InvalidRequest, MethodNotFound, InvalidParams, InternalError, ServerError). Errors are serialized as JSON-RPC 2.0 error objects with detailed messages and optional error data. Includes error context preservation (stack traces, original error objects) for debugging while sanitizing sensitive information in client responses.
Unique: Implements MCP-compliant error serialization with automatic error code mapping and context preservation, ensuring errors are both informative for debugging and safe for client consumption. Includes stack trace management for development vs. production.
vs alternatives: More protocol-aware than generic error handlers because it enforces MCP error codes and JSON-RPC 2.0 format; more secure than raw error propagation because it includes sanitization and context filtering.
Generates TypeScript interfaces and types from MCP tool schemas, resource definitions, and prompt templates. Includes strict type checking for tool arguments, resource URIs, and template variables. Generated types are exported as .d.ts files or inline type definitions, enabling IDE autocomplete and compile-time type validation in handler implementations.
Unique: Generates TypeScript types directly from MCP schemas, enabling compile-time type validation and IDE autocomplete for tool arguments and resource access. Includes strict type checking for handler implementations.
vs alternatives: More type-safe than runtime validation because it catches errors at compile-time; more complete than generic JSON Schema type generators because it includes MCP-specific metadata (tool names, resource URIs).
