MCP server for declarative intent execution. Agents submit intents — transfers, swaps, multi-hop routes — and the engine resolves and executes them atomically.

Provides structured access to Solana Anchor error data, enabling AI coding agents to parse logs, debug transactions, and look up error codes.

Made-to-order data for AI agents via x402 micropayments on Base. Describe a need in plain language, get a custom quote, pay per call. No signup, no API keys. HTTP + MCP transports. 5 tools.

Enables an AI assistant to inspect, validate and step-debug Cardano transactions and Plutus scripts, including finding failing redeemers, explaining ledger/CBOR/CDDL errors, decompiling UPLC, and opening highlighted problems in cquisitor or de-uplc-web.

Cross-chain cryptocurrency swaps via Chainflip. Get quotes, execute swaps, and track progress. No API key required to get started.

Universal HTTP 402 Micropayment Protocol & Autonomous Economic Settlement Engine for AI Agents on Base L2.

Enables generating on-chain attestations of agent service performance across Ethereum, Polygon, Arbitrum, Optimism, and Base, plus audit trail retrieval, attestation verification, and price lock lookup.

On-chain delivery receipts for x402 AI-agent payments on Solana: anchors SHA-256 digests of delivered content to a PDA after settlement; buyers verify proof of delivery offline with zero trust in the seller. Live MCP endpoint + npm bridge.

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.

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

Inspects and debugs Solana transactions, accounts, Anchor IDLs, errors, and PDAs from MCP-compatible clients.

Generates MCP servers from smart contract ABIs, enabling Claude to interact with any Ethereum contract via natural language commands.

Unified MCP console for OKX's full ecosystem, integrating CEX, onchain, predictions, and AI agent features.

fomox402 broker + MCP server for last-bidder-wins games on Solana. Drop one URL into Claude / Cursor / Goose / Cline and the agent auto-registers a Privy-managed Solana wallet (faucet-funded with ~0.0024 SOL + $fomox402), bids via x402 micropayments, claims dividends, and plays autonomously. 14 tools wired up — register_agent, place_bid, claim_winnings, claim_dividend, list_games, get_me, etc. Str

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

Wallet-funded MCP client for six paid Utilia tools: Solana priority fees, transaction diagnosis and simulation, token-risk checks, PDF-to-Markdown, and audio normalization over x402. MIT-licensed and installable from npm.

Provides 205 tools for the Basis protocol on BNB Smart Chain, enabling trading, token creation, prediction markets, staking, loans, and more via natural language.

Exposes a remote catalogue of paid x402 routes as MCP tools, proxying calls and paying USDC on Base with the x402 protocol. Returns results alongside the on-chain settlement transaction hash, with a free catalogue tool for inspection.

Provides a three-layer payment firewall for AI agents, enabling identity verification, risk screening, and execution authorization with on-chain policy enforcement for secure and auditable transactions.

Enables AI agents to read Robinhood Chain stock-token positions, quote swaps, and execute swaps through the Model Context Protocol, bridging on-chain assets that Robinhood's own off-chain MCP cannot reach.

Local MCP-to-browser signing bridge for EVM, Solana, and Sui, letting agents prepare and simulate transactions while users approve and sign in a browser wallet extension.

Decentralized Git with on-chain governance, bounties, and DAOs. Tools for repos, issues, PRs, labels, releases, bounties, and DAO proposals. Auto-wallet on first use, trust tiers, and approval mode for human-in-the-loop.

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 curriculum that teaches AI agents how to spend their own money. Sixteen lessons from "what is a wallet" to your first x402 purchase. Teacher, not butler — never signs, pays, or holds keys.

MCP server for Bags on Solana. Reads token analytics, creator-fee data and trade quotes; executes swaps and fee claims only behind a token gate, a hard SOL spend cap, and a single-use confirmation token bound to the exact arguments. The first call to a write tool signs nothing — it returns a preview. 14 tools, 337 tests at 100% coverage enforced in CI, mainnet-only writes, npm provenance.

Enables AI agents to discover and analyze prediction markets, execute trades, and manage positions on Polymarket via the Model Context Protocol.

Enables Claude to discover new Solana meme tokens, assess their risk, inspect on-chain positions, and prepare or optionally execute buy/sell transactions under configurable spend and risk guardrails. It also logs plans and trades to Google Sheets for review.

Enables AI agents to autonomously quote, execute, and verify on-chain payments in USDG on Robinhood Chain (chainId 4663) under spending policy caps, alongside live PONS price, launch-token metadata, market, and balance lookups. Payments are signed, broadcast, and only marked confirmed once the on-chain receipt and expected USDG transfer event verify.

Enables AI agents to autonomously quote, execute, and verify USDG payments on Robinhood Chain 4663 under configurable spending caps, while accessing PONS price, token, balance, and launch-market intelligence through MCP tools.
