A2A + Amp: Complete MCP Integration

A2A is a MCP server that An MCP server that bridges the Model Context Protocol (MCP) with the Agent-to-Agent (A2A) protocol, enabling MCP-compatible AI assistants (like Claude) to seamlessly interact with A2A agents..

When integrated with Amp, you can:

• Register and manage A2A agents for communication
• Send messages to A2A agents and handle responses
• Manage asynchronous tasks and retrieve results

This guide provides step-by-step instructions to set up A2A in Amp, including configuration, examples, and troubleshooting.

What You'll Achieve

After completing this setup:

• A2A will be fully integrated and operational
• You can use A2A tools directly in Amp
• All A2A capabilities will be available for your workflows
• Access to 4 different tools

Prerequisites

Before starting, ensure you have:

• Amp installed and configured
• Compatible operating system (macOS, Linux, Windows (WSL))

Installation

Step 1: Install A2A

Configuration

Step 2: Configure Amp

1. Locate your configuration file:

2. Add server configuration:

Configure MCP servers in VS Code/Cursor settings.json:

```json
{
  "amp.mcpServers": {
    "playwright": {
      "command": "npx",
      "args": ["-y", "@playwright/mcp@latest", "--headless", "--isolated"]
    },
    "semgrep": {
      "url": "https://mcp.semgrep.ai/mcp"
    },
    "sourcegraph": {
      "url": "${SRC_ENDPOINT}/.api/mcp/v1",
      "headers": {
        "Authorization": "token ${SRC_ACCESS_TOKEN}"
      }
    },
    "linear": {
      "command": "npx",
      "args": ["mcp-remote", "https://mcp.linear.app/sse"]
    }
  }
}

Or add servers via CLI:

# Add HTTP-based server
amp mcp add sourcegraph --header "Authorization=token your-token" https://sourcegraph.example.com/.api/mcp/v1

# Add SSE-based server
amp mcp add linear https://mcp.linear.app/sse

# OAuth login for authenticated servers
amp mcp oauth login my-server \
  --server-url https://example.com/.api/mcp/v1 \
  --client-id your-client-id \
  --client-secret your-client-secret \
  --scopes "openid,profile,email"

3. **Restart Amp**

Completely quit and restart Amp to load the new configuration.



## Examples

Once configured, you can use A2A in Amp:

### Register and Communicate with Agent

Set up communication with an A2A agent

**Ask Amp:** "Register an agent for data analysis tasks and send it a dataset processing request"

**Expected Result:** Agent registered, task submitted, and task_id returned for tracking

### Stream Real-Time Data

Use streaming to get real-time updates from agent

**Ask Amp:** "Stream live updates from the monitoring agent about system metrics"

**Expected Result:** Continuous stream of system metrics and status updates

### Manage Multiple Agents

Coordinate tasks across multiple A2A agents

**Ask Amp:** "List all available agents and distribute parallel processing tasks"

**Expected Result:** Agent list displayed, tasks distributed, and progress tracked

### Handle Task Results

Retrieve and process completed task results

**Ask Amp:** "Get the results from the data analysis task I submitted earlier"

**Expected Result:** Task results retrieved with processed data and analysis findings



## Testing Your Setup

1. Launch Amp
2. Verify A2A is available in the tools list
3. Test basic A2A functionality



## Troubleshooting

### Common Issues

#### Agent Registration Failed

**Symptoms:** Registration errors, Agent not found, Connection timeouts

**Cause:** Network connectivity issues or invalid agent configuration

**Solution:**
- Check internet connectivity to A2A network
- Verify agent endpoint URLs are correct
- Ensure agent is online and accepting connections
- Check firewall settings and port accessibility

#### Task Never Completes

**Symptoms:** Task stuck in pending state, No response from agent

**Cause:** Agent overload, network issues, or task complexity

**Solution:**
- Check agent status and availability
- Cancel and resubmit the task
- Break complex tasks into smaller parts
- Try different agent if available

#### Transport Protocol Errors

**Symptoms:** Connection refused, Protocol mismatch errors

**Cause:** Incorrect transport configuration or port conflicts

**Solution:**
- Verify MCP_TRANSPORT setting matches client expectations
- Check MCP_HOST and MCP_PORT are accessible
- Ensure no port conflicts with other services
- Try different transport mode (stdio, http, sse)

#### Message Streaming Issues

**Symptoms:** Broken streams, Incomplete messages, Timeout errors

**Cause:** Network instability or buffer overflow

**Solution:**
- Check network stability and bandwidth
- Reduce message frequency or size
- Enable debug logging to trace issues
- Use appropriate buffer sizes for streaming

#### MCP Server Not Connecting

**Symptoms:** Server not appearing in tools, Connection timeout, Authentication errors

**Cause:** Invalid configuration, missing credentials, or network issues

**Solution:**
- Verify server URL and command are correct
- Check environment variables are set properly
- For OAuth servers, run amp mcp oauth login
- Review amp logs for error messages

#### Tool Execution Fails

**Symptoms:** MCP tools available but not working, Error messages during execution

**Cause:** Server dependencies missing or permission issues

**Solution:**
- Verify required environment variables are configured
- Check amp.permissions settings for tool restrictions
- Test MCP server independently
- Review server-specific documentation

#### Permission Denied

**Symptoms:** Tool blocked by permission system, Ask prompts for every action

**Cause:** Permission rules restricting MCP tool usage

**Solution:**
- Review amp.permissions in settings.json
- Add allow rules for trusted MCP servers
- Use amp permissions edit to modify rules

#### A2A not appearing in Amp

**Symptoms:** Server not listed, Tools not available

**Cause:** Configuration or installation issue

**Solution:**
- Verify configuration syntax
- Check A2A installation
- Restart Amp
- Check logs for error messages
