An MCP server for fetching verifiable random numbers from the drand network.
Drand becomes available to MCP clients through the drand mcp server. An MCP server for fetching verifiable random numbers from the drand network.
Use verifiable randomness in your AI application. This Model Context Protocol (MCP) server enables you to get a random value from the drand network, verify its validity and use it as an input seed to your model-driven flows!
Once connected, the assistant can call these 3 tools directly:
get-randomness-latest — noneget-randomness-by-time — time in millisecondsget-randomness-by-round — roundSetup follows the standard MCP pattern: clone or install the server, then register it in your client's configuration file and restart the client. The configuration snippets on this page cover Claude Desktop, Claude Code and Cursor.
fetch is required)Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. Drand sits in that group, and the shape of its toolset — get-randomness-latest, get-randomness-by-time, get-randomness-by-round — tells you what it is really for. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.
| Tool | What it does |
|---|---|
| get-randomness-latest | none |
| get-randomness-by-time | time in milliseconds |
| get-randomness-by-round | round |
