Pay-per-call MCP server for on-chain blockchain data including wallet profiles, token metrics, protocol TVL, and gas prices.

A remote MCP server that links World ID 4.0 sessions to AI assistants, enabling verified human authentication and tools for claiming Founding Human places, accessing human grants, and interacting with a verified human wall.

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.

Trace hidden insider wallet clusters behind Solana tokens before you ape — safety score, honeypot & LP-lock check, no signup for first 5 calls/day.

A server that enables interaction with the Solana blockchain, providing access to over 40 Solana RPC methods including getting balances, transaction details, block information, and sending transactions.

23 tools for AI agents working with Nostr Open source. No API key. No account. NIP-46 remote signing Publish notes, reply, react, repost Encrypted DMs (NIP-04 + NIP-44) Fetch events, profiles, social graph

A Model Context Protocol server that enables Claude AI to interact with the Solana blockchain, allowing it to execute transactions, query accounts, manage wallets, get price predictions, trade tokens, and access various blockchain data sources.

Enables AI agents to read and bid on a paid message slot on Solana, with enforced spend limits, dry-run proposals, and an append-only audit log for every write.

Enables read-only verification of Unlock Protocol lock membership on-chain, checking whether a wallet holds a valid key for a lock on supported networks.

On-chain rug-pull & honeypot risk screen for ERC-20 tokens, providing a SAFE / CAUTION / HIGH-RISK verdict based on live public RPC reads.

MCP server for researching tokenized real-world assets on Solana. It provides on-chain tools for checking token controls, supply, liquidity, and premium, plus published research from Metis.

A wallet for AI agents: test funds, payments, paid APIs and escrow on Aether. Give an AI agent its own wallet on Aether, a proof-of-work chain with post-quantum (ML-DSA-44) signatures. The agent gets an address and testnet funds in one step, then sends and receives AETH or USDC under per-payment and daily limits you set. It can pay for APIs that answer HTTP 402, sell its own, rate the services it

Enables Claude to turn a described beat into a loopclub deep link for auditioning and renting on-chain by encoding track specs into a ?jam= URL and returning an ASCII grid. It also supplies vocabulary, genre examples, and a jam prompt to help generate idiomatic loops.

Connects AI agents and developers to structured blockchain data across multiple networks through Nodit's Web3 infrastructure, enabling easy querying, analysis and interaction with blockchain ecosystems without specialized development expertise.

Let your AI assistant pay for web content in USDC (x402 on Base) within a budget you set. Inside the budget it pays on its own; above it you are asked to confirm. The wallet key stays on your computer. For claude.ai and ChatGPT there is a remote server (https://agent.p2flux.com/mcp) where you approve each payment in your own browser wallet.

Blockchain JSON-RPC on 23 EVM chains for AI agents — Ethereum, Base, Arbitrum, plus young chains like Robinhood Chain, Plasma and Ink. Free reads with no key; heavy methods (eth_getLogs, trace, debug) via a free API key or x402 USDC pay-per-call.

A server that exposes blockchain data (balances, tokens, NFTs, contract metadata) via the Model Context Protocol, enabling AI agents and tools to access and analyze blockchain information contextually.

Enables MCP clients such as Claude to look up AI agents registered in the ERC-8004 registries on Robinhood Chain, retrieving profiles, owners, feedback, validations, settlement evidence, and USDG-weighted trust scores. It is read-only and requires no wallet or API key, and can be reached either as a hosted remote endpoint or locally via npx.

Enables AI agents to price, deploy, pay for, monitor, update, and cancel applications on a decentralized cloud using a generated key pair, with plain-language specs converted into validated network specifications. Also provides container logs, live instance stats, and network or pricing guidance as read-only tools.

Connects AI agents to a Safe smart-account wallet so they can discover DAO proposals and cast votes as the Safe off-chain on Snapshot and on-chain through OpenZeppelin or Compound-style Governors.

Enables AI assistants to discover and inspect Solana tokens on justi.fun, explain protocol rules and fee splits, quote trades, and build unsigned swap and launch transactions for a user's wallet to sign — without ever holding keys or sending transactions.

Enables Robinhood Chain trading agents to obtain quotes, policy-checked unsigned public-swap calldata, simulations, hook information, prices, and deployment discovery without holding keys or signing transactions.

Provides read-only access to public referral deals and codes, races and leaderboards, DeFi interface restriction data, x402 catalogs, cp0x facts, and open-source repository listings. Supports natural-language queries such as finding deals for a venue or checking interface restrictions by country.

Enables AI agents to obtain on-chain DEX aggregator quotes computed by the on-chain Quoter contract through their own RPC node, returning verified unsigned swap calldata, simulations, token info, deployment registry checks, and live staking solvency. All tools are read-only and keyless, so the agent never signs or holds a private key.

Enables AI agents to generate or import multi-chain keys, sign messages and unsigned transactions, broadcast them, and query native balances across Ambient, Solana, BSC, and Arbitrum. Private keys stay encrypted on the local machine, so agents can complete the sign-and-send half of a swap, liquidity, or bridge workflow handed over by a remote market server.

A Model Context Protocol server that enables AI assistants to interact with Hedera blockchain in real-time, allowing them to check account balances, view block information, and estimate transaction costs.
