CLI Coding Agents Meet MuleSoft MCP Server

As an Integration and DevOps engineer, I’ve spent countless hours staring at black and white screens — vim, vi, nano, writing, running, testing, and shipping scripts, all from one home:

The OG

echo "terminal"

Coding agents just moved in.

## GitHub Copilot

After experimenting with IDE coding agents — building MuleSoft applications using MuleSoft Vibes/ACB right inside VS Code — I wanted to take it further. Back to where I’m most comfortable.

Let’s spin up a CLI coding agent, and arm it with MuleSoft DX MCP Server to interact with Anypoint Platform - straight from the terminal.

MuleSoft DX MCP Server

MuleSoft DX MCP Server supports API design, application deployment, and asset management

Features

• API specification development
• Application creation and configuration
• Agent network creation
• Asset publication in Exchange
• Instance deployment and management to CloudHub 2.0 and Runtime Fabric
• Application security

These features look very promising for a CLI agent. Let’s set them up.

Prerequisites

• Enable Agentforce for Anypoint platform - Ref
• Install Node.js 20 or later - Ref
• Organization admin access to create a connected app - Ref

Connected App Creation

• Log in to Anypoint Platform.
• Under Access Management, click Connected Apps.
• Click Create App. Add a name for the connected app.
• Select App acts on its own behalf (client credentials).
• Click on Add Scopes. Add the scopes mentioned in the below table.

• Click on Save to save the new connected app.

The OG: Terminal

• Now open The OG: Terminal. Set the environment variables for the terminal session.

macOS/Linux

export ANYPOINT_CLIENT_ID="<CLIENT_ID>"
export ANYPOINT_CLIENT_SECRET="<CLIENT_SECRET>"

Optional

export ANYPOINT_REGION="<REGION_NAME>"

Windows

$env:ANYPOINT_CLIENT_ID="<CLIENT_ID>"
$env:ANYPOINT_CLIENT_SECRET="<CLIENT_SECRET>"

Optional

$env:ANYPOINT_REGION="<REGION_NAME>"

CLI Coding Agents

Setup is complete on the Anypoint side and the env variables are set in the terminal. Let’s make the terminal smarter and equip it with MuleSoft DX MCP Server.

• Antigravity
• Copilot

Antigravity

• Install Antigravity CLI following the link
• Run the below command to start CLI. Log in using your google/gemini account.

agy

• Type /mcp, press Enter.

MCP Servers

  No MCP servers configured.

Keyboard: ↑/↓ Navigate  enter Actions

esc to cancel                                 

• As of now, no MCP servers are configured for antigravity-cli.

MCP Server configuration

• Antigravity lets you setup MCP server as Global setup or Workspace Local setup.

Global: ~/.gemini/antigravity-cli/mcp_config.json

Workspace local setups: .agents/mcp_config.json

• Update mcp_config.json as below.

{
  "mcpServers": {
    "mulesoft": {
        "command": "npx",
        "args": ["-y", "mulesoft-mcp-server", "start"]
    }
  }
}

• Make sure that env variables were properly set for the terminal session.
• Let’s start antigravity.

agy

• Type /mcp, press Enter.

Plugins (~/.gemini/antigravity-cli/plugins)
>  ✓ mulesoft  Tools: create_mule_project, generate_mule_flow, create_mcp_server, deploy_mule_application, list_applications, +16 more

Keyboard: ↑/↓ Navigate  enter Actions

If you see the message similar to above then you are all set and ready to perform operations 😄

But wait, is it too easy????

Let’s get the hands dirty 😈

My initial prompts didn’t work and, it was not able to list the MCP tools 😞 Countless hours and tokens wasted 😫!!!

I kept on trying…. I kept trying, and then I changed the /model to Claude Sonnet 4.6, and prompted:

list mcp tools

A good output 😎

Another prompt

List deployed applications in dev environment.

Another success 😎

Copilot

• Install the copilot following the link
• Run the below command to check if copilot is working.

copilot

• Type /login and press enter. Follow instructions to log in to your GitHub account and activate GitHub Copilot.
• To view list of available MCP servers type /mcp show and press enter.

As of now only GitHub MCP server is enabled.

MCP Server configuration

• Type /mcp add and press enter. Fill in details as per below table.

• ctrl+s to save the MCP server configuration.

Prompt

List deployed applications in dev environment.

Now, CLI agent has got MuleSoft DX MCP Server.
