It runs as a zero-dependency, stdlib-only MCP stdio server for clients such as Claude Desktop, Cursor, and Windsurf.

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

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.

Enables querying Base Network blockchain data including blocks, transactions, balances, and smart contracts on mainnet and testnet.

MCP server for Chainlink Runtime Environment, enabling build, simulate, deploy, and manage CRE workflows from any MCP client.

MCP server for Spazio Genesi's attestation service that enables AI agents to attest, verify, and check digital works with full privacy, as file bytes never leave the device.

Enables reading live market state on Arc (chainId 5042) including launchpads, LP APRs, RPC consensus, token screens, honeypot simulations, and an agent directory.

Read-only MCP (stdio) server for the socseal settlement venue — prove a payment MINED on-chain, read the public settlement book, anchor receipts. No KYC, no custody, fail-closed. Experimental, R=0 external payers.

Provides access to Mina blockchain data, enabling queries for events, actions, and network state information through a standardized interface.

Exposes protocol, indexer, market, checkout, and cash-flow operations to agents through read-only, cash-preparation, and full operator profiles, with state-changing actions previewed before execution unless explicitly authorized.

MCP server for temporal state queries and cryptographic audit trails. Query historical entity state at any point in time, generate Merkle proofs of past state, and anchor contract snapshots for immutable provenance.

Provides AI agents with seamless access to Filecoin's decentralized storage network for persistent file storage and dataset management. It features automatic payment handling, CDN support, and cost estimation tools for efficient storage operations.

Provides AI agents with access to DFNS documentation, API reference, and SDK code through full-text search and type intelligence.

Provides a persistent memory layer for Stellar and Soroban projects, scanning repositories to create a knowledge graph of contracts, storage, and on-chain state. Exposes this memory to AI agents via MCP, enabling project overview, search, and context recovery.

Provides complete HTTP/JSON access to all 100+ Emercoin RPC endpoints with integrated formatting utilities. Enables blockchain operations, name system management, wallet functions, and mining operations through a comprehensive REST API interface.

Enables AI agents to access Hyperliquid's full API through deterministic tool mappings, supporting DeFi operations and market data retrieval via natural language.

Provides LLM access to Unicity gaming platform games through a payment-gated day pass system. Supports game discovery, access management, and payment processing via Nostr protocol and Unicity blockchain.

Enables AI assistants to interact with the Rexi API through a comprehensive wrapper that provides access to all API endpoints with full parameter support. Includes OpenAPI specification resources and schema access for blockchain and contract-related operations.

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.

Rug pull risk scores and on-chain forensics for memecoins on Solana, Ethereum, Base and Robinhood Chain - launch-bundle detection, funding-origin tracing, deployer history, insider networks and whale flow. 15 read-only tools.

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.

Enables agents to search and inspect live service offerings, generate x402 payment snippets, and understand blockchain-only balance policies.

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.

MCP server for RugGuard, enabling AI agents to perform pre-trade rug checks on tokens, with paid tools for token scanning and pre-trade verification, and a free metrics resource.

An MCP server that gives autonomous coding agents deterministic, schema-validated tools for EVM smart contract development — security scanning, gas profiling, compiler diagnostics, and transaction simulation.
