Reduce MCP tool count by 10-100x. TypeScript framework that groups related operations behind discriminators, with automatic schema generation, type-safe validation, token-optimized descriptions, and hierarchical grouping for enterprise-scale APIs.

`mcp-fusion` is an advanced TypeScript framework designed to consolidate numerous Model Context Protocol (MCP) operations into a single, intelligent LLM tool. It addresses context exhaustion and routing confusion by utilizing build-time multiplexing and context gating for scalable, precise API interactions.

Features

01Build-Time Multiplexing & Context Gating: Consolidates related operations under a single tool, reducing LLM context pressure and routing hallucinations.
024-Tier Per-Field Annotation Intelligence: Automatically generates precise field requirement annotations (e.g., 'Always Required', 'Required-For') for the LLM.
03Zod Parameter Stripping & Type Safety: Merges and strips unknown parameters using Zod, ensuring security and type-safe handlers at runtime.
04Tag-Based Selective Tool Exposure: Controls which tools the LLM sees per session, optimizing token usage for 5,000+ endpoints.
05Pre-Compiled Middleware Chains: Executes global or group-scoped middleware at runtime with zero chain assembly or closure allocation per request.

    Fewer tools means cleaner model decisions about which tool to use.

    Good for MCP servers that have grown to unwieldy tool counts over time.

    Reducing MCP tool count by 10-100x by grouping related operations is a real improvement.

    Tool grouping is intelligent — related operations share context and reduce redundancy.
