# Creating Your First vMCP

This tutorial will guide you through creating your first vMCP that aggregates multiple MCP servers.

## Prerequisites​

- vMCP installed and running (see Installation)
- At least one MCP server configured

## Step 1: Navigate to vMCPs Page​

1. Open http://localhost:8000 in your browser
2. Click on "vMCPs" in the navigation menu

You'll see the vMCP management interface.

## Step 2: Create a New vMCP​

Click the "Create vMCP" button. This opens the vMCP creation dialog.

### Fill in Basic Information​

- Name: Give your vMCP a descriptive name (e.g., "Development Tools")
- Description: Explain what this vMCP is for (e.g., "Aggregates filesystem and git tools for development")

## Step 3: Add MCP Servers​

In the "MCP Servers" section:

1. Click "Add Server"
2. Select an MCP server from the dropdown
3. Set the priority (lower numbers = higher priority)
4. Add more servers as needed

Example Configuration:

    Server 1: filesystem (Priority: 1)
    Server 2: github (Priority: 2)
    Server 3: postgres (Priority: 3)

### Understanding Priority​

When multiple servers provide the same tool name, vMCP uses priority to determine which one to call:

- Priority 1 = Highest (called first)
- Priority 2 = Second choice
- Priority 3 = Third choice, etc.

## Step 4: Configure Active Config (Optional)​

The "Active Config" section allows you to set runtime parameters that can be used with variable substitution.

Example:

    {
      "default_repo": "myorg/myrepo",
      "api_key": "your-api-key",
      "workspace_path": "/home/user/projects"
    }

These values can be referenced in tool calls using `@config:key_name`:

    {
      "repo": "@config:default_repo"
    }

## Step 5: Save Your vMCP​

Click "Create" to save your vMCP.

You'll see your new vMCP appear in the list with:

- Server count
- Active status
- Configuration indicator
- Creation date

## Step 6: Test Your vMCP​

### View Available Tools​

1. Click on your vMCP card
2. In the dropdown menu, select "View Tools"
3. You'll see all tools from all connected servers

### Use with MCP Client​

Your vMCP is now available at:

    mcp://localhost:8000/vmcps/{vmcp_id}

Configure your AI agent or MCP client to connect to this endpoint.

## Example: Development vMCP​

Here's a complete example for local development:

Name: Development Tools

Description: Local development with filesystem, git, and documentation access

Servers:

- filesystem (Priority: 1)
- git (Priority: 2)
- memory (Priority: 3)

Active Config:

    {
      "workspace": "/home/user/projects/myapp",
      "default_branch": "main"
    }

This vMCP gives your AI agent access to:

- File operations (read, write, list)
- Git operations (commit, push, pull)
- Memory/context storage
- All tools can reference the workspace path via `@config:workspace`
