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

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

Enables AI agents to certify documents, prove agreements, and verify counterparty claims with on-chain receipts on Hedera Hashgraph. Provides tools for document certification, two-party attestation, and agent registration with zero-config setup.

Enables agents to mint Ashfields NFTs on Ethereum by burning 100,000 $ASH per token, check wallet and mint status, approve allowances, and trigger royalty distributions.

Enables AI agents to look up XRPL domain availability, pricing, profiles, portfolios, and transaction status, and to get registration links for signing in the user's own wallet.

A read-only Model Context Protocol server for the Thru blockchain alphanet, enabling account queries, transaction status, program events, name service resolution, faucet status, and network health via the official @thru/sdk.

A read-only MCP server that lets any MCP-compatible AI agent inspect wallets and contracts on Base directly through natural conversation.

Provides MCP tools to query Etherscan for Ethereum blockchain data—ETH balances, ERC-20 tokens, transactions, contract ABIs, and gas prices—without requiring an API key.

Thin MCP wrapper around the SQD Portal API for blockchain data queries across multiple networks including EVM, Solana, Bitcoin, Substrate, and Hyperliquid. Provides 25 public tools for discovery, cross-chain queries, and chain-specific operations.

An MCP server for Klever blockchain smart contract development, providing contextual knowledge including code patterns, best practices, and runtime behavior.

Enables AI agents to build, test, deploy, invoke, and inspect Soroban smart contracts on the Stellar network through structured MCP tools and resources.

Read-only MCP server for querying DERO blockchain — blocks, smart contracts, transactions, network info. Privacy-first, runs locally.

Hashlock Markets (hashlock.markets) — sealed-bid intent-based crypto trading protocol with HTLC atomic settlement. AI agents can create, commit, and validate trading intents on Ethereum, Bitcoin, and Sui. Canonical npm package: @hashlock-tech/mcp. Not the cryptographic hashlock primitive, not Hashlock Pty Ltd (hashlock.com).
