Comput3AI MCP Plugin

A powerful integration plugin that bridges ElizaOS with the Model Context Protocol (MCP), enabling your AI agents to harness multiple MCP servers for enhanced capabilities.

🌟 Overview

The Model Context Protocol (MCP) is a revolutionary open protocol that creates a seamless bridge between Large Language Models (LLMs) and external resources. It standardizes how AI applications interact with external data and tools, making integration simple and efficient.

✨ Key Features

This plugin supercharges your ElizaOS agents by providing access to multiple MCP servers, each offering unique capabilities:

• Smart Resources: Access and utilize contextual data and information
• Dynamic Prompts: Leverage templated messages and workflows
• Powerful Tools: Execute sophisticated functions and operations

🚀 Getting Started

create an account on https://comput3.ai/

top up your account and launch gpus

get your eliza agent on

git clone https://github.com/elizaos/eliza-starter.git
cd eliza-starter
cp .env.example .env
pnpm i && pnpm build && pnpm start

add compute3 configurations to the .env file.

            }
          },
    }
}

⚙️ Configuration Options

MCP supports two types of servers: "stdio" and "sse". Each type has its own configuration options.

Common Options

Option	Type	Description
type	string	The type of MCP server: "stdio" or "sse"
name	string	The display name of the server
timeout	number	Timeout in seconds for tool calls (default: 60)
disabled	boolean	Whether the server is disabled

stdio Server Options

Option	Type	Description
command	string	The command to run the MCP server
args	string[]	Command-line arguments for the server
env	object	Environment variables to pass to the server
cwd	string	Optional Working directory to run the server in

sse Server Options

Option	Type	Description
url	string	The URL of the SSE endpoint

🛠️ Using MCP Capabilities

Once configured, the plugin automatically exposes MCP servers' capabilities to your agent:

Context Providers

The plugin includes three providers that add MCP capabilities to the agent's context:

1. MCP_SERVERS: Lists available servers and their tools, resources and prompts

🔄 Plugin Flow

The following diagram illustrates the MCP plugin's flow for tool selection and execution:

  "plugins": ["@elizaos/plugin-mcp", "other-plugins"],
  "settings": {
    "mcp": {
      "servers": {
        "github": {
          "command": "npx",
          "args": ["-y", "@modelcontextprotocol/server-github"],
          "env": {

          }
        },
        "puppeteer": {
          "command": "npx",
          "args": ["-y", "@modelcontextprotocol/server-puppeteer"]
        },

          "command": "npx",
          "args": ["-y", "@modelcontextprotocol/server-google-maps"],
          "env": {
            "GOOGLE_MAPS_API_KEY": "<YOUR_API_KEY>"
          }
        }
      },
      "maxRetries": 2
    }
  }
}

🔒 Security Considerations

Please be aware that MCP servers can execute arbitrary code, so only connect to servers you trust.

🔍 Troubleshooting

If you encounter issues with the MCP plugin:

1. Check that your MCP servers are correctly configured and running
2. Ensure the commands are accessible in the ElizaOS environment
3. Review the logs for connection errors
4. Verify that the plugin is properly loaded in your character configuration
