Provides a standardized MCP server factory that handles initialization, request routing, and graceful shutdown. The core exports server construction patterns that abstract away protocol-level details, allowing developers to focus on tool and resource definitions rather than managing WebSocket/stdio transports, message serialization, or error propagation across the MCP specification.
Unique: Provides opinionated MCP server scaffolding with built-in patterns for tool registry and request routing, reducing boilerplate compared to raw MCP SDK usage while maintaining full protocol compliance
vs alternatives: Faster to production than implementing MCP servers from scratch with the raw SDK, with less protocol-level complexity than building custom RPC frameworks
Implements a centralized registry that maps tool definitions (name, description, input schema) to handler functions, with automatic JSON Schema validation and type coercion. Tools are registered declaratively with OpenAI-compatible function calling schemas, and the registry handles parameter validation, error wrapping, and result serialization before returning to the MCP client.
Unique: Combines declarative tool registration with automatic JSON Schema validation and OpenAI-compatible function calling format, eliminating manual schema-to-function mapping boilerplate
vs alternatives: More structured than ad-hoc tool registration, with built-in schema validation that catches parameter mismatches before execution, unlike raw function arrays
Defines a pluggable KV interface that abstracts storage backends (in-memory, Redis, DynamoDB, etc.) behind a consistent get/set/delete/list API. The interface uses async/await patterns and supports TTL, batch operations, and optional namespacing, allowing servers to persist state without coupling to a specific storage implementation.
Unique: Provides a minimal, async-first KV interface that decouples MCP servers from storage implementation, with optional namespacing for multi-tenancy without requiring a full database abstraction layer
vs alternatives: Simpler than full ORM/database abstractions while still enabling backend flexibility, with explicit async patterns that match MCP's async request handling
Exposes a Host interface that provides runtime context about the execution environment (platform, available resources, client capabilities, configuration). The server can query host properties to adapt behavior (e.g., enable/disable features based on client support), and the interface supports lazy initialization of expensive resources like database connections.
Unique: Provides a Host abstraction that enables servers to query runtime capabilities and adapt behavior without hardcoding environment assumptions, with lazy resource initialization to minimize startup overhead
vs alternatives: More flexible than environment variable configuration alone, allowing servers to adapt to client capabilities and resource availability at runtime without code changes
Defines an Auth interface for pluggable authentication strategies (API keys, OAuth, mutual TLS, custom schemes) with support for token validation, permission checking, and audit logging. The interface integrates with the tool registry to enforce per-tool access control, allowing servers to implement fine-grained authorization without modifying tool handlers.
Unique: Provides a pluggable Auth interface that integrates with the tool registry for declarative per-tool access control, enabling multi-tenant MCP servers without modifying tool implementations
vs alternatives: More granular than simple API key validation, supporting multiple auth strategies and per-tool permissions while remaining decoupled from tool logic
Implements a middleware chain pattern for intercepting and transforming MCP requests and responses. Middleware can validate requests, enrich context, transform payloads, log events, or enforce policies before tools execute. The pipeline is composable and supports both sync and async middleware, with error handling that propagates failures back to the MCP client.
Unique: Provides a composable middleware pipeline integrated with the MCP request lifecycle, supporting both sync and async middleware with shared context propagation and error handling
vs alternatives: More flexible than per-tool decorators, allowing cross-cutting concerns to be applied uniformly across all tools without modifying tool code
Enables servers to expose resources (documents, files, data streams) alongside tools, with support for streaming large payloads and content negotiation. Resources are defined with URIs and MIME types, and the interface handles chunked delivery to MCP clients, allowing tools to reference and manipulate resources without loading entire contents into memory.
Unique: Integrates resource streaming with the tool registry, allowing tools to declare dependencies on resources and MCP clients to access them via URI without coupling to file system or storage implementation
vs alternatives: More efficient than embedding large payloads in tool responses, with streaming support that prevents memory exhaustion on large files
Provides standardized error handling that converts exceptions and validation failures into MCP-compliant error responses with structured error codes, messages, and optional context. The system distinguishes between client errors (invalid parameters), server errors (tool execution failures), and protocol errors, with proper HTTP-like status codes and error serialization.
Unique: Provides MCP-compliant error handling with structured error codes and context propagation, distinguishing between client/server/protocol errors without requiring manual error wrapping in tool code
vs alternatives: More structured than generic exception handling, with MCP-specific error serialization that ensures clients receive properly formatted error responses
