Provides access to NFTGo's Developer API for retrieving NFT collection details, asset information, market data, wallet information, and search capabilities on the Ethereum blockchain.

Allows LLM agents and MCP clients to analyze blockchain data including wallet balances, token information, and transaction history across EVM and Solana chains through the Dune API.

An x402-native API that compares real-time gas prices across up to 9 EVM chains and recommends the cheapest one, enabling users to optimize transaction costs for trading agents and DeFi bots.

Enables interaction with blockchain networks through the Rosetta API standard for Internet Computer Protocol (ICP). Supports operations like account balance queries, transaction construction and submission, block retrieval, and network status checks.

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

Provides AI agents with 71 tools to query Etherscan's blockchain analytics via the Etherscan API, with no authentication required.

Enables AI agents to access 48 real-time crypto data tools including prices, DeFi, meme tokens, gas, sentiment, Solana, and agent commerce, with post-paid billing via Solana USDC.

Provides AI assistants with a comprehensive toolkit for developing, testing, and deploying smart contracts on the Agoric blockchain. It supports key Agoric features such as the Zoe contract framework, ERTP asset handling, and cross-chain orchestration patterns.

An MCP server for executing token swaps on the Solana blockchain using Jupiter's Ultra API, enabling users to fetch optimal swap orders and execute transactions with slippage control.

Enables lookup of Nostr profiles and checking of Vertex API credit balance using the Vertex API.

Enables AI agents and quantitative traders to query block-accurate DeFi telemetry across Morpho Blue, Ethena, Fluid, Sky, Euler V2, and Pendle V2, including stablecoin carry/arbitrage radar and pre-trade risk simulation. It provides atomic Multicall3 reads, post-trade utilization and APY slippage checks, cap headroom decoding, and Pendle TWAP/logit-curve analysis through REST and MCP-compatible endpoints.

Enables Claude to increment and query a counter deployed on the Linera blockchain via natural language, using an Apollo MCP server bridge.

An MCP server that enables cross-chain token swapping between different blockchains using 1inch Fusion+ API, along with portfolio management tools for tracking assets across chains.

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.

MCP Server for the Luno Cryptocurrency API

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.

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.

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, HyperEVM, Robinhood Chain, Solana and Tron.

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.

Exposes nine purpose-built tools for EVE: Frontier on Sui Move, covering Smart Assembly contract coding, Smart Gate route and toll planning, Network Node gigajoule optimization, Smart Turret targeting, killmail threat intel, SSU market making, zkLogin character verification, sovereignty fuel tracking, and PTB drain simulation.
