ZetaChain universal blockchain MCP server
Connect Universal to Claude, Cursor or any other MCP client and it stops being a tab you switch to. ZetaChain universal blockchain MCP server. The universal mcp server is what makes that connection.
A comprehensive Model Context Protocol (MCP) server for universal blockchain development, providing full access to ZetaChain CLI, Foundry, and cross-chain functionality through AI assistants.
Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
create_project — Create new universal contract projects with templatescheck_foundry — Verify Foundry (forge, cast, anvil) installation and versionsCross-Chain — cross_chain_send, cross_chain_status, bridge_statusPrerequisites — The Prerequisites tool exposed by this serverDevelopment — The Development tool exposed by this serverConfiguration is passed through the environment: ZETACHAIN_CLI_PATH, SMITHERY_API_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Universal's toolset — create_project, check_foundry, Cross-Chain and 2 more — is a fair guide to whether it matches your workflow. It is maintained by ExpertVagabond; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
