FAQ from NEAR Protocol Full-Featured MCP Server

Is this server secure for production environments?

No, storing the mnemonic in an environment variable is not secure for production. Use a more secure key management solution.

What is an MCP client?

An MCP client is an application that can connect to MCP servers, such as Claude for Desktop.

How do I specify which account to use?

You can specify the account ID in the tool function call. If no account ID is provided, the server will use its own account.

What are the prerequisites for running this server?

Node.js (v16+), npm, a NEAR account (optional), and an MCP client (optional).

What do I do if the server is not appearing in Claude?

Double-check the claude_desktop_config.json syntax, verify the absolute path to build/index.js, and restart Claude Desktop completely.
