RandomWeb3MCP is a random element generation service based on EVM block hash. The service provides various random element generation tools that can be used in games, finance, testing, and other fields.

MCP server for Helius — Solana blockchain data access for AI assistants, provided by Solana's fastest, most reliable infrastructure provider

A simple MCP server implementation that provides AI models with basic Solana RPC methods and helpful development prompts.

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

Enables AI models to interact with the Lightning Network by providing an MCP-compliant API to pay invoices.

Checks live x402 routes across Base, Solana, and Algorand before agents spend. $0.003 USDC settles only for a valid live eligible route; normal typed misses are not settled. Free preview and validate tools. Seller payment is separate; the agent keeps its wallet. Optional signed route-binding receipts support buyer-side checks.

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.

Rescues USDC, USDT and USDG from wallets with no gas. Agents check a wallet for stuck or frozen stablecoins, quote a send or a swap into the gas coin, collect the wallet signature and track the transfer. Base, Arbitrum, Ethereum, Polygon, Avalanche, BNB Chain, HyperEVM, Robinhood Chain, Solana and Tron.

Read-only on-chain query surface for the AgentCivics civil registry on Sui — soulbound AI-agent identities, on-chain memories, reputation, refusal records. Hosted, no install, no keypair. For write tools (register, write_memory, record_refusal), install the npm package @agentcivics/mcp-server locally and supply your own keypair.

Live Proof-of-Work mining data for AI agents: difficulty, hashrate, solo-mining odds, cost of production and hardware profitability across 126+ networks and 770+ ASIC/GPU/CPU models. Sourced and timestamped, read-only.

Enables MCP-capable agents to retrieve a tamper-evident decomposition of x402 network growth on Base and to place $399 human-reviewed endpoint or wallet audits paid over the x402 rail, without moving funds itself.

Enables AI assistants to access live mining data for 126+ proof-of-work networks and 770+ hardware models, including network difficulty, hashrate, solo-mining odds, cost of production, hardware profitability, and mining news.

Screens the counterparty of an x402 payment before an agent pays it. One tool, screen_payment, checks address sanity, dynamic-payTo swaps, transport safety and your spend policy, then returns allow / review / block with the reasons — advisory only, and by default it runs with no key, no account and no network call.

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.

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

Keyless CEX/DEX order signing for AI trading agents (Binance, OKX, Bybit, KuCoin, Hyperliquid, Asterdex). Exchange keys stay inside an AWS Nitro Enclave — the agent gets policy-bounded signatures, never credentials. Built to survive prompt injection and supply-chain key leaks.

An MCP server that enables cross-chain token transfers via the Stargate protocol.

Enables AI agents to post a task with quality levels, have a frontier model hired and graded on BrainChain, and pay only when the delivered work passes, with automatic refunds otherwise.

Pre-trade token safety check for AI agents. Simulates a sell before you buy, then reports honeypot, tax, liquidity, pair age, same-ticker impersonation and owner powers as one low/medium/high/unknown verdict. Fail-closed: when a critical check cannot run it answers unknown rather than guessing low. Publishes its own measured error rate with the benchmark harness in the repo.

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.

Verifies blockchain-anchored timestamp proofs entirely on the user's machine, with five tools: hash a file, verify a file against a proof, verify a known hash against inline proof data, explain what a proof asserts, and create a new proof through ProofLedger. Verification recomputes the SHA-256 and walks the Merkle path locally instead of asking the issuer; only create uses the network.

Provides a non-custodial USDC wallet on Base for AI agents, with human-in-the-loop approval for every payment.

MCP server for DeFi execution — lets AI agents swap, provide liquidity, lend, bridge, and run yield strategies across 22 chains in a single transaction. 7 tools for token discovery, portfolio analysis, quoting, and execution via the Haiku API.

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

AI travel agent over MCP — live flights, hotels, activities, and events worldwide, then completes the booking on autonomad.ai.

MCP server for the AKKA Finance DEX aggregator — swap quotes, routes, and execution across EVM chains.

Crypto token unlock calendar for the next 60 days: each unlock rated by size against circulating supply, with recipients, futures availability, a track record of price moves before past unlocks, and on-chain checks of locked team and investor wallets.

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.

Enables LLMs to compile and verify Tolk smart contract code for the TON blockchain.

Pay-per-call data and tools for AI agents over x402, by UnyKorn. 360 endpoints: DeFi and market data, multi-chain wallet reads, wallet and token risk signals, SEC filings, web and domain intel, and AI text tools. Settled per call in USDC on Base ($0.001-$0.25). No API keys or subscriptions; unpaid calls return the exact quote first.
