Twig

kind-ling/twig
STDIOregistry active
Summary

Twig scores your MCP tool descriptions on a 0-100 scale across intent match, specificity, and differentiation, then generates optimized variants designed to increase LLM selection rates. The free tier gives you `analyze` and `optimize` commands that work against agent.json files, MCP servers, or OpenAPI specs. Paid monitoring tracks your score weekly and shows competitive position in categories like crypto-defi or data-feeds. The underlying model weights how well your description matches actual agent search queries (40%), whether it specifies outputs and constraints (35%), and how distinct you are from competitors (25%). If you're getting indexed but not called, this tells you why and gives you three rewrite options: functional, structured, and contextual.

Twig

Agents choose you or they don't. Twig makes them choose you.

The Problem

Every MCP tool has a description. That description is what an LLM reads when deciding whether to call your service. It's the only signal between "selected" and "skipped".

Most descriptions are garbage.

ToolCurrent DescriptionTwig Score
exa/answer"AI-powered answer"F (28/100)
wordspace/invoke"Run wordspace AI agent loop"F (31/100)
exa/find-similar"Find similar pages"F (33/100)
jupiter/portfolio"Wallet portfolio positions"D (42/100)

These tools are useful. Their descriptions are not. And getting indexed in x402-discovery or MCPay doesn't help if agents skip you because they can't tell what you do.

Getting indexed is table stakes. Twig helps you get chosen.


Quick Start

npm install -g @kind-ling/twig
# Free — score your descriptions
twig analyze https://myservice.com/.well-known/agent.json

# Free — get optimized variants
twig optimize https://myservice.com/.well-known/agent.json

# Paid — set up weekly monitoring
twig monitor https://myservice.com/.well-known/agent.json

# Paid — see how you rank in your category
twig competitive crypto-defi

# Paid — see what agents are actually searching for
twig intents crypto-defi

Live API

Twig is available as a hosted API at https://twig.kind-ling.com

# Health check
curl https://twig.kind-ling.com/health

# Analyze any MCP server
curl -X POST https://twig.kind-ling.com/analyze \
  -H "Content-Type: application/json" \
  -d '{"url": "https://your-mcp-server.com/mcp"}'

# Optimize descriptions
curl -X POST https://twig.kind-ling.com/optimize \
  -H "Content-Type: application/json" \
  -d '{"url": "https://your-mcp-server.com/mcp", "category": "crypto-defi"}'

Response format:

{
  "ok": true,
  "url": "https://your-mcp-server.com/mcp",
  "output": "🔍 Analyzing...\n  Score: 72/100 (C)\n  ..."
}

No API key required for public endpoints. Rate limits apply.


Scoring Model

Three dimensions, 0–100 each:

DimensionWeightWhat it measures
Intent Match40%Similarity to top agent queries for your category
Specificity35%Output format, parameters, constraints, examples present?
Differentiation25%Do you stand out from similar services in your category?

Grades: A (85+) · B (70+) · C (55+) · D (40+) · F (<40)

Score below 40 = agents are skipping you.


What Twig Monitors

Your descriptions — re-scored weekly against a live intent corpus. Score changes alert you when your positioning drifts.

Your competitive position — how you rank vs. similar services in your category. Know when a competitor improves and overtakes you.

Intent trends — what agents are searching for this week vs. last. The queries change. Your descriptions need to keep up.

Volume correlation — description changes mapped to x402 volume changes. Close the loop between optimization and revenue.


Optimization Variants

Twig generates 3 variants per tool:

Functional — Action verb + what + return type:

"Answers questions with real-time web sources. Returns a cited response with source URLs, confidence score, and supporting quotes. Best for research and fact-checking."

Structured — Input → output with constraints:

"Web Q&A. Input: question string. Returns: answer (string), sources (URL array), confidence (0-1). Supports: factual queries, current events, research synthesis."

Contextual — Use case → action → output (highest LLM selectability):

"Use when you need a factual answer with sourced citations. Queries the web in real-time and synthesizes a response with URLs and supporting quotes. Best for research, fact-checking, and current events."


Before / After

exa/answer

Before: AI-powered answer ← F (28/100)

After (Contextual): Use when you need a factual answer with sourced citations. Queries the web in real-time and synthesizes a response with source URLs and supporting quotes. Best for research, fact-checking, and current events. ← B (72/100)

wordspace/invoke

Before: Run wordspace AI agent loop ← F (31/100)

After (Structured): Executes a Wordspace multi-step agent workflow. Input: task description and optional context. Returns: completed output, intermediate steps, tool calls made. Best for complex tasks requiring multiple tool invocations. $2/call. ← B (74/100)


Revenue Model

Standard (Monitoring)

Weekly reports are gated via x402 on Base. Set up once, runs automatically.

twig monitor 0xYourWallet --url https://myservice.com/.well-known/agent.json

Enterprise (Performance-based)

For services with existing x402 volume:

  1. twig measure 0xWallet --baseline — record 7-day baseline
  2. Deploy Twig-optimized descriptions
  3. twig measure 0xWallet --compare — measure delta (14–30 days later)
  4. Pay 15% of the revenue increase in USDC on Base
  5. Revenue flat or down? Pay nothing.

Everything measured via on-chain USDC transfer logs. No self-reporting.


Supported Sources

  • A2A Agent Cards (/.well-known/agent.json)
  • MCP servers (JSON-RPC tools/list)
  • OpenAPI specs
  • Local JSON schema files
  • x402-discovery catalog (for competitive analysis)
