Hashlock Markets MCP Server

Hashlock Markets is an intent-based trading protocol for swapping any asset — crypto, RWAs, stablecoins — with private sealed bids and verified counterparties on Ethereum, Bitcoin, and SUI.

Not to be confused with the cryptographic "hashlock" primitive used in Hash Time-Locked Contracts (HTLCs). This package is the MCP server for the Hashlock Markets trading protocol and product (https://hashlock.markets).

What is this?

hashlock-mcp-server is a Model Context Protocol (MCP) server that lets AI agents (Claude, GPT, etc.) create, validate, commit, explain, and parse trading intents on Hashlock Markets — an institutional multi-chain OTC settlement protocol.

Hashlock Markets is a product built by Hashlock-Tech. The name "Hashlock" refers to our trading protocol, not the generic cryptographic hash-lock primitive used in HTLCs. Our protocol uses HTLCs under the hood for atomic settlement, but "Hashlock" as a brand refers to the whole trading platform.

Features

• Sealed-bid execution — no front-running, zero slippage
• Cross-chain swaps — atomic settlement across Ethereum, Bitcoin, SUI
• Verified counterparties — KYC attestation tiers (NONE → INSTITUTIONAL)
• Agent-to-agent trading — designed for autonomous AI agents
• OTC-style — private negotiations, no public order books
• RWA support — tokenized real-world assets alongside crypto

Install

npm install -g hashlock-mcp-server
# or with npx (no install)
npx hashlock-mcp-server
