Autonomous M2M compliance and trust APIs for AI agents (KYB, OFAC, VAT, Sanctions checking).

Enables querying indexed blockchain data via subgraph GraphQL queries, part of the Pipeworx MCP gateway.

Provides a tool for dynamic and reflective problem-solving through structured sequential thinking, and automatically stores logs to the Recall network for on-chain persistence.

MCP server that prepares Proof of Invention (POI) transaction requests for submission

An MCP server that lets AI agents autonomously buy physical hats using USDC on Base — no credit card, no checkout, no human required. Browse the catalog, get a real-time shipping quote, send crypto, and we ship the hat.

498 MCP tools across 12 industry verticals. Marketplace, escrow, DeFi, legal, healthcare, insurance, construction, and trades. USDC payments on Base L2.

On-chain crypto indicators (EMA, RSI, VWAP, Bollinger) via Chainlink oracles.

Enables AI agents to interact with the Lido protocol for ETH staking, position management, and governance participation across Ethereum and L2 networks. It provides tools for querying balances, simulating transactions, and executing complex workflows like withdrawals and DAO voting through a safety-first interface.

Cross-chain bridge aggregator MCP server for AI agents. Compares routes across LI.FI, deBridge, Relay, Across and Squid to find the best rate. Use when an agent needs to bridge or swap tokens between EVM chains, Solana, or Cosmos. The aggregator of aggregators.

Comprehensive MCP server for the Sui blockchain with 53 tools covering wallets, DeFi (Cetus, DeepBook), SuiNS, staking, validators, Move introspection, and full RPC. Enables natural language interaction with the entire Sui ecosystem.

An MCP server providing access to Telos, a philosophical AI mentor that combines rationalist thinking with stoic philosophy to offer personalized guidance and smart contract accountability on Solana.

Enables agents to purchase and use compute resources on Robinhood Chain via x402 payments. Provides tools for thinking, renting GPUs, checking balances, and viewing the compute menu.

Enables on-chain attestation of any content onto the DigiByte blockchain, providing permanent, timestamped, tamper-evident proofs. Allows AI agents to notarize their outputs or verify attestations using only the blockchain.

Enables tamper-evident anchoring of file, text, or JSON hashes to the BSV blockchain via MCP tools, with verification and lookup capabilities.

Non-custodial on-chain escrow + AI arbitration for agent-to-agent USDC payments on Base. Seven tools wrap a verified EscrowV1 contract — create, deliver, confirm, dispute, resolve — with read-only introspection if no wallet key is provided.

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

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.

MCP server for the CortexCloud API, enabling pay-per-call AI generation, web search, market data, and blockchain RPC endpoints via the x402 protocol, billed in USDC on Base without API keys or subscriptions.

Decodes Ethereum calldata and returns a safety verdict with plain-English explanations of what the transaction does, flagging dangerous actions like unlimited approvals or gasless permits.

Deploys AI agents on-chain into the Metaplex Agent Registry on Solana, minting Core assets with EIP-8004 identity. Supports self-custodial signing via server keypair or external wallets, with devnet support for free rehearsal.
