Hive MCP Server

What is Hive MCP Server?

Hive MCP Server is an MCP server that enables AI assistants (like Claude) to interact with the Hive blockchain through the Model Context Protocol. It allows AI models to read blockchain data, perform authenticated actions like voting and posting, send tokens, and handle encrypted messaging.

How to use Hive MCP Server?

Install it via npx -y @gluneau/hive-mcp-server and configure required environment variables (HIVE_USERNAME, HIVE_POSTING_KEY, HIVE_ACTIVE_KEY, HIVE_MEMO_KEY) for authenticated operations. Then add the server to your MCP client configuration (e.g., Claude Desktop's claude_desktop_config.json). For read-only data tools, no authentication is needed.

Key features of Hive MCP Server

FAQ from Hive MCP Server

What dependencies does Hive MCP Server require?

It uses @hiveio/dhive (Hive blockchain client), @modelcontextprotocol/sdk, and zod for schema validation. Node.js is required.

Where does the data live?

All data is fetched from or written to the Hive blockchain. The server does not store any data locally.

Do I need authentication for all tools?

No. Read-only tools (e.g., get_account_info, get_posts_by_tag) work without authentication. Tools that write to the blockchain require environment variables with the appropriate private keys.

What key types are used for authentication?

The posting key is used for content operations (voting, posting, commenting), the active key for token transfers, and the memo key for encrypted messaging.

What transport does this server use?

This MCP server uses stdio transport and is invoked as a command-line process. It integrates with MCP clients such as Claude Desktop, Windsurf, and Cursor.
