A comprehensive toolkit for Ethereum blockchain analysis within Claude AI, enabling contract auditing, wallet analysis, profitability tracking, and on-chain data retrieval.

Enables AI agents to read live Shopify catalog snapshots, detect product, price, and stock changes against stored baselines, and produce competitor intelligence reports across single stores or batches of up to 50. Paid tiers settle automatically in USDC on Base through the x402 protocol, requiring no platform account or payment processor.

Enables agents to assess counterparty risk, token danger, and wallet creditworthiness on Base by analyzing contract powers and controlling wallet reputation.

Enables AI agents to verify Israeli companies and assess supplier invoice and payment risk before sending funds, exposing registry-backed evidence, company-change events, invoice gates, and x402 payee-trust checks with deterministic PAY/HOLD/BLOCK and ALLOW/REVIEW/DENY outcomes. It also provides free previews and schema/service discovery tools over remote MCP.

Methodology-transparent BTC + ETH whale forensics. 30 tools, anonymous OAuth 2.1 Free tier.

Real-time prediction market intelligence for AI agents. Query Polymarket and Kalshi markets, wallet profiles, smart money leaderboards, social pulse signals, price candlesticks, and orderbook data — 13 agents, one MCP connection. Powered by 1.1TB+ of historical data.

Provides access to measured x402 ecosystem data, allowing users to query which merchants actually accept payment (verified by real on-chain settlements) and explore market concentration and health statistics.

AI-powered smart contract security analysis for AI agents and developers, enabling scanning of Solidity repos for vulnerabilities.

MCP server that lets AI agents search the substreams.dev package registry.

Read-only MCP server for discovering and ranking on-chain agents on Stellar mainnet via natural language search, reputation probes, and profile lookups.

Enables interaction with lightning addresses and common lightning tools via your LLM, providing Lightning Network functionality through natural language.

Enables MCP clients to use paid tools for secret scanning, agent-config auditing, and OG image rendering, with payments handled over the x402 protocol on Base.

MCP server for managing TON blockchain sites, deployments, DNS, and storage via the Resistance Tools platform.

Provides Clockchain's verified-time primitives, notarization, smart-contract scheduling, audit trails, and agent identity verification to any MCP client.

Enables AI agents to interact with Ethereum smart contracts through Anvil, providing capabilities to read Solidity code, simulate and execute transactions, manipulate blockchain state, query events, and test contracts in isolated environments for development and auditing workflows.

Enables AI agents to inspect the public NFH protocol corpus, verify census status, and prepare bounded Ethereum wallet intents for claims and non-custodial market actions while never signing or submitting transactions.

Enables natural language interaction with the Avalanche blockchain through AI assistants, allowing users to execute Avalanche CLI commands and AvalancheJS API operations without technical knowledge.
