The Story / 故事

I noticed Claude Skills works amazingly well — Claude dynamically discovers and loads only the skills it needs, avoiding context overload.

But most agent frameworks? They dump 500+ tool definitions into the context at once. And MCP responses? Often 10,000+ chars of raw data that waste your tokens.

Then I discovered UTCP — exactly what I needed! Progressive tool discovery built-in. And Cloudflare’s Code Mode? One code block executes everything. Brilliant!

So I built on top of UTCP: Progressive Discovery + Code Mode + LLM Filtering — the smarter way to use MCP.

The best part? Just add one config block. Works with Claude Desktop, Windsurf, Cursor, Dify, and any MCP-compatible client. No extra servers needed.

Looking for…?

• ✅ Claude Skills alternative for your MCP setup
• ✅ Better MCP tool management without context overload
• ✅ Progressive tool discovery — load tools on demand
• ✅ OpenAPI/Swagger to tools — register REST APIs as tools
• ✅ MCP token optimization — reduce 90%+ token waste
• ✅ MCP response filtering — smart summarization

You’re in the right place.

What is this?

LLMs are great at writing code, but terrible at tool calling.

Traditional MCP exposes tools directly to LLMs — but LLMs struggle with:

• Too many tools (500+ definitions = confusion)
• Huge responses (10,000+ chars = wasted tokens)
• Multiple round trips (15+ API calls = slow & expensive)

utcp-mcp-gateway fixes all of this:

Traditional:  User → LLM → Tool1 → LLM → Tool2 → LLM → Tool3 → Result
              (15+ calls, $26/day, slow)

Code Mode:    User → LLM writes code → Execute all at once → Result  
              (1 call, $0.87/day, fast)

Result: $9,536/year savings (benchmark source)
