Open MCP

Open MCP is an open-source initiative from Holoworld that applies the Model Context Protocol to on-chain work, letting AI agents query chains, call contracts and reach DeFi protocols. The obstacle to agent deployment is interface fragmentation: remote calls differ per chain and methods differ per protocol, so developers write an adapter for each pairing and agents cannot reuse existing capability.

Delivery comes through the EVM Agent Kit, a TypeScript library wrapping balance queries, contract reads and writes, and protocol routing. Agents discover capability from a standard tool manifest and validate arguments against a structured schema before invoking, while the server side is exposed as an MCP server that desktop clients and code editors can load. The same descriptions let agents call one another without rewriting integrations per model. The tool manifest describes argument types and return values in JSON, so a client lists available capability once loaded.
