Market Data Toolkit

18 live market-data tools for AI agents, served over the Model Context Protocol. One URL connects your agent to real eBay sold prices, luxury watch market analysis, company KYC for the UK and Spain, SEC filings, patents, trademarks, government contracts and public auctions.

This is a remote MCP server: the tools run as Apify Actors behind the Apify MCP gateway. There is nothing to install or host. Every tool queries its source live at request time and returns clean, typed JSON.

Pricing

Pay per event, on your Apify account. Each tool charges a flat fee per delivered result (from $0.0008 to $0.12 depending on the tool). Failed lookups and empty responses are never charged. No subscription.

Example prompts

• "What is a Game Boy Micro actually selling for? Should I buy one listed at 60 EUR?"
• "Run a risk check on Greggs plc and summarize the red flags."
• "Which fund managers increased their NVDA position last quarter?"
• "Any new trademark filings close to the name 'Acme' I should worry about?"
• "Find cybersecurity contract opportunities closing in the next 30 days."

Design principles

• Primary and official sources wherever they exist (SEC EDGAR, Companies House, BOE, TMview, ClinicalTrials.gov, SAM.gov).
• Answers, not raw scrape dumps: valuation stats instead of listing rows, filings parsed into transactions, risk flags computed from register facts.
• Agent-native: typed output schemas, defaults that work with zero configuration, one flat fee per unit of value.
