"Reverse engineering or reverse direction search" matching MCP servers:

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.

Pay-per-use semantic web search for AI agents. Powered by SearxNG, agents pay in sats via Lightning Network micropayments — no API keys required.

This MCP wraps Bitrefill public API to allow agents to search for products and shop using cryptocurrencies like Bitcoin, Ethereum, Solana, and many more.

Read-only XRPL token and wallet checks with issuer-aware explanations, impersonation checks and spoken summaries. Built for Zach Riehn's XRP Ledger Trading Lab by AI coding agents under Zach's direction. Never signs or sends transactions; findings describe observed ledger evidence, not a guarantee of safety or investment advice. Try it: https://cocoeatsai.com/trading-lab/token-guard/

Pay-per-use contextual guidance for AI agents. When an agent loses direction, it describes its state, pays 21 sats via Lightning or Arbitrum ETH, and receives its original purpose stripped of noise.

Signal-first Bitcoin intelligence over MCP — sovereign adoption, hiring velocity, and network hashrate as leading, non-price signals with strength, direction, rationale, and primary sources. Information, not financial advice.

Read-only MCP server that lets AI agents resolve DNS domains, .cns names and ENS names to owners, public profiles and freshly verified on-chain payment addresses across 28 networks, so agents can pay an address the owner actually published. It exposes lookup, payment-address, reverse-lookup, availability and network-listing tools without any ability to sign, register or move funds.

Enables AI assistants to resolve .i Web3 domains, reverse lookup wallet addresses, fetch profile records, check domain availability, and retrieve multichain addresses via the DotI protocol.

Enables resolving ENS names to Ethereum addresses and profile records, and reverse-resolving addresses to ENS names, all without requiring an API key.

Enables agents to resolve ENS names to Ethereum addresses and reverse-resolve addresses to ENS names, including avatar URLs, through a pay-per-call x402 micropayment API.

AI-Powered Cryptocurrency Direction Prediction & Market Signal Analysis

Provides read-only tools to query live Polymarket prediction-market data via the public Gamma API, enabling search, browsing, and detailed market and event information.

Enables AI agents to make pay-as-you-go AI inference requests through x402 with automatic Solana USDC payments, no API keys or registration, while enforcing configurable spending limits.

Enables agents to search and inspect live service offerings, generate x402 payment snippets, and understand blockchain-only balance policies.

Keyless crypto payments for AI agents. One MCP call turns any wallet address into a non-custodial crypto payment link or tip jar, no API key and no account, with funds settling straight to your wallet at a 0% platform fee (USDC/USDT, BTC, LTC, DASH, DOGE, ZCASH).

Resolves a company name, registrable domain, or LEI to its GLEIF legal entity record — LEI, legal name, jurisdiction, entity status, and registration status — for $0.05 USDC on Base paid per call over x402, with no signup or API key. Includes a free, no-wallet preview of price and coverage plus hard per-call and per-session spend caps, while misses and ambiguous matches cost nothing.

Enables static security audit of Solidity smart contracts by analyzing source code or deployed bytecode for vulnerabilities, providing risk scores and detailed findings.

Connects AI assistants to Solodit's 49,000+ blockchain vulnerability database, enabling search, browse, and lookup of audit findings directly from your AI workflow.

Quick-scan a smart contract for rug, honeypot, or centralization risk before sending funds. It combines verified source, live on-chain state, and heuristic Solidity analysis to return a SAFE/CAUTION/HIGH-RISK verdict.
