DVMCP: Data Vending Machine Context Protocol

A monorepo containing packages that bridge Model Context Protocol (MCP) servers with Nostr's Data Vending Machine (DVM) ecosystem, enabling AI and computational tools to be discovered and utilized via Nostr's decentralized network.

Packages

This monorepo contains the following packages:

@dvmcp/bridge

The bridge implementation that connects MCP servers to Nostr's DVM ecosystem. Handles tool announcement, execution, and status updates.

@dvmcp/discovery

A MCP server/discovery service that aggregates MCP tools from DVMs and makes their tools available.

@dvmcp/commons

Shared utilities and components used across DVMCP packages.

Installation & Usage

Prerequisite: Ensure you have Bun installed.

Quick Start with NPX (No Installation)

You can run the packages directly using npx without installing them:

# Run the bridge
npx @dvmcp/bridge
# Run the discovery service
npx @dvmcp/discovery

The interactive CLI will guide you through configuration setup on first run.

Global Installation

# Install the packages globally
npm install -g @dvmcp/bridge @dvmcp/discovery
# Run the commands
dvmcp-bridge
dvmcp-discovery

Setting Up a Bridge

To expose your MCP server as a DVM on Nostr:

1. Navigate to the directory where you want to configure the bridge
2. Run: npx @dvmcp/bridge
3. Follow the interactive setup to configure:

• Your MCP server path
• Nostr private key (or generate a new one)
• Relays to connect to

1. The bridge will start and begin proxying requests between Nostr and your MCP server

Setting Up a Discovery Service

To aggregate MCP tools from DVMs:

1. Navigate to your desired directory
2. Run: npx @dvmcp/discovery
3. Follow the setup to configure:

• Nostr private key
• Relays to monitor
