"Semantic UI" matching MCP servers:

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.

MCP server for Pi Network that enables AI agents to query Pi chain data (balances, transactions) and verify user tokens, with optional payment sending that is off by default.

Provides AI agents with direct access to the Ray Group DeFi UX rubric, named patterns, and cognitive-bias glossary for grounded UX assessments of DeFi protocols.

Agent tools for the Ophis intent-based DEX: parse, quote, build, relay orders, look up fee tiers.

Live liquidity-pool scores for Solana + EVM: Enter/Hold/Exit verdicts and a composite 0-100 Wealthville Score, backed by a public, immutable track record that includes misses. Read-only, free, no key required. Data product, not financial advice.

On-chain Solana cabal & rug detection as an MCP server. Scans any Solana token mint before your agent buys and returns an Exit-Liquidity Risk verdict.

Provides local access to Aztec documentation, examples, and source code via cloned repositories, with optional semantic search for enhanced querying.

Agent-friendly semantic classification of all subgraphs on The Graph Network. Pre-computed index of 15,500+ subgraphs with domain classification, protocol type detection, schema fingerprinting, canonical entity mapping, and composite reliability scoring.

Zero-knowledge proof generation MCP server. AI agents can prove identity claims (Coinbase KYC, Country, Google OIDC, Google Workspace, Microsoft 365) without revealing personal data. Runs in AWS Nitro Enclave TEE with x402 USDC payments.

Live verifiable on-chain data for the $BOBAI token on BNB Chain: price computed from pair reserves × Chainlink (no price API), liquidity depth with LP-burn proof, buyback-and-burn audit trail, and fee-on-transfer-safe trade params. 13 read-only tools + 2 guided prompts, no API key.

Provides access to ODEI's constitutional knowledge graph, AI safety guardrails, and EVM smart contract auditing tools. It enables users to query structured domain nodes, validate agent actions, and perform security audits directly through an MCP client.

On-chain Solana token safety for trading agents — traces coordinated wallet funding, same-block Jito bundles, serial-rug deployers and live coordinated dumps into one Exit-Liquidity Risk verdict before a swap. Free tier, then $0.02 USDC/query via x402.

Enables AI agents to discover, evaluate, and purchase live data from the Macaroon Network marketplace using semantic search, metadata checks, and Bitcoin Lightning payments.

Enables AI assistants to resolve CIMS parties, quote and send transfers, handle attestation, and track intent lifecycles on the Roots CIMS network, with built-in safety rails that refuse raw addresses and require confirmation before sending.

Enables access to 86 crypto data endpoints from the Surf API, including market data, wallets, social sentiment, on-chain queries, and more, through dynamically generated MCP tools.

AI-powered smart contract forge with an 8-agent adversarial security audit system. Generate, audit, fix, and compile Solidity and Anchor/Rust contracts across 8 chains.

Pre-trade DeFi intelligence for AI agents. 20 paid x402 endpoints, USDC on Base.

Zero-human Web3 micropayment MCP agent for LLM-ready clean web scraping, YouTube transcripts, PDF paper extraction, and plain text on Polygon Mainnet.
