AgentSignal

npm version GitHub stars License: MIT MCP Tools

The collective intelligence layer for AI shopping agents.

Every agent that connects makes every other agent smarter. 1,200+ shopping sessions, 95 products, 50 merchants, 10 categories — and growing.

Why this exists: When AI agents shop for users, each agent starts from zero. AgentSignal pools decision signals across all agents so every session benefits from what every other agent has already learned — selection rates, rejection patterns, price intelligence, merchant reliability, and proven constraint matches.

Quick Start (30 seconds)

Remote — zero install, instant intelligence:

{
  "mcpServers": {
    "agent-signal": {
      "url": "https://agent-signal-production.up.railway.app/mcp"
    }
  }
}

Local via npx:

npx agent-signal

Claude Desktop / Claude Code:

{
  "mcpServers": {
    "agent-signal": {
      "command": "npx",
      "args": ["agent-signal"]
    }
  }
}

One Call to Start Shopping Smarter

The smart_shopping_session tool logs your session AND returns all available intelligence in a single call:

smart_shopping_session({
  raw_query: "lightweight running shoes with good cushioning",
  category: "footwear/running",
  budget_max: 200,
  constraints: ["lightweight", "cushioned"]
})

Returns:

Your session ID for subsequent logging
Top picks from other agents in that category
What constraints and factors mattered most
How similar sessions ended (purchased vs abandoned)
Network-wide stats

23 MCP Tools

Smart Combo Tools (recommended)

Tool	What it does
`smart_shopping_session`	Start session + get category intelligence + similar session outcomes — all in one call
`evaluate_and_compare`	Log product evaluation + get product intelligence + deal verdict — all in one call

Buyer Intelligence — Shop Smarter

Tool	What it tells you
`get_product_intelligence`	Selection rate, rejection reasons, which competitors beat it and why
`get_category_recommendations`	Top picks, decision factors, common requirements, average budgets
`check_merchant_reliability`	Stock accuracy, selection rate, purchase outcomes by merchant
`get_similar_session_outcomes`	What agents with similar constraints ended up choosing
`detect_deal`	Price verdict against historical data — best_price_ever to above_average
`get_warnings`	Stock issues, high rejection rates, abandonment signals
`get_constraint_match`	Products that exactly match your constraints — skip the search

Seller Intelligence — Understand Your Market

Tool	What it tells you
`get_competitive_landscape`	Category rank, head-to-head win rate, who beats you and why, price positioning
`get_rejection_analysis`	Why agents reject your product, weekly trends, what they chose instead
`get_category_demand`	What agents are searching for, unmet needs, budget distribution, market gaps
`get_merchant_scorecard`	Full merchant report — stock reliability, price competitiveness, selection rates by category

Discovery & Monitoring

Tool	What it tells you
`get_budget_products`	Best products within a specific budget — ranked by agent selections, with merchant availability
`get_trending_products`	Products trending up or down — compares current vs previous period selection rates
`create_price_alert`	Set a price alert — triggers when agents spot the product at or below your target
`check_price_alerts`	Check which alerts have been triggered by recent agent activity

Write Tools — Contribute Back

Tool	What it captures
`log_shopping_session`	Shopping intent, constraints, budget, exclusions
`log_product_evaluation`	Product considered, match score, disposition + rejection reason
`log_comparison`	Products compared, dimensions, winner, deciding factor
`log_outcome`	Final result — purchased, recommended, abandoned, or deferred
`import_completed_session`	Bulk import a completed session retroactively
`get_session_summary`	Retrieve full session details

Example: Full Agent Workflow

# 1. Start smart — one call gets you session ID + intelligence
smart_shopping_session(category: "electronics/headphones", constraints: ["noise-cancelling", "wireless"], budget_max: 400)

# 2. Evaluate products — get intel as you log
evaluate_and_compare(session_id: "...", product_id: "sony-wh1000xm5", price_at_time: 349, disposition: "selected")
evaluate_and_compare(session_id: "...", product_id: "bose-qc45", price_at_time: 279, disposition: "rejected", rejection_reason: "inferior ANC")

# 3. Compare and close
log_comparison(products_compared: ["sony-wh1000xm5", "bose-qc45"], winner: "sony-wh1000xm5", deciding_factor: "noise cancellation quality")
log_outcome(session_id: "...", outcome_type: "purchased", product_chosen_id: "sony-wh1000xm5")

Every step feeds the network. The next agent shopping for headphones benefits from your data.

Example: Seller Intelligence Workflow

# 1. How is my product performing vs competitors?
get_competitive_landscape(product_id: "sony-wh1000xm5")
# → Category rank #1, 68% head-to-head win rate, beats bose-qc45 on ANC quality

# 2. Why are agents rejecting my product?
get_rejection_analysis(product_id: "bose-qc45")
# → 45% rejected for "inferior ANC", agents chose sony-wh1000xm5 instead 3x more

# 3. What do agents want in my category?
get_category_demand(category: "electronics/headphones")
# → Top demands: noise-cancelling (89%), wireless (82%), unmet need: "spatial audio"

# 4. How does my store perform?
get_merchant_scorecard(merchant_id: "amazon")
# → 34% selection rate, 2% out-of-stock, cheapest option 41% of the time
