AgentRPC + Claude Code: Complete MCP Integration

AgentRPC is a MCP server that Connect to any function, any language, across network boundaries using AgentRPC..

When integrated with Claude Code, you can:

• Register functions across languages and networks
• Call functions across network boundaries
• List all registered functions across languages

This guide provides step-by-step instructions to set up AgentRPC in Claude Code, including configuration, examples, and troubleshooting.

What You'll Achieve

After completing this setup:

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

Prerequisites

Before starting, ensure you have:

• API secret from AgentRPC dashboard
• Claude Code installed and configured
• Compatible operating system (Windows, macOS, Linux)

Installation

Step 1: Install AgentRPC

Configuration

Step 2: Configure Claude Code

1. Install Claude Code

Download and install Claude Code from the official website

Visit: https://claude.ai/code

Note: Claude Code is available as a native application, not via npm

2. Navigate to Project

Open terminal in your project directory where you want to use the MCP server

3. Install MCP Server

Install the MCP server you want to use (e.g., via npm, pip, or other package manager)

4. Configure MCP Server

Add MCP server configuration to project CLAUDE.md file or use --mcp-config flag

Note: CLAUDE.md is preferred for project-specific configuration

5. Test Integration

Start Claude Code and verify MCP server is working

claude

Note: Use interactive mode to test MCP server functionality

Configuration Details

Add to your project's CLAUDE.md file:

## MCP Servers

### AgentRPC
- **Installation**: agentrpc
- **Configuration**: "AGENTRPC_API_SECRET": "rpc_secret_1234567890",
        "AGENTRPC_NAMESPACE": "my-team-functions"
- **Description**: Connect to any function, any language, across network boundaries using AgentRPC.

Claude Code will automatically detect and load MCP servers from your project context.

Examples

Once configured, you can use AgentRPC in Claude Code:

Multi-Language Microservices

undefined

Ask Claude Code: "Call Python ML model from TypeScript app via Go API"

Expected Result: undefined

Cross-Cloud Function Calls

undefined

Ask Claude Code: "Execute distributed data processing across three clouds"

Expected Result: undefined

Kubernetes Function Registry

undefined

Ask Claude Code: "List available functions in production cluster"

Expected Result: undefined

Testing Your Setup

1. Run claude in your project directory
2. Ask Claude to list available tools and verify AgentRPC tools are present
3. Test AgentRPC functionality by asking Claude to use specific tools

Test commands:

claude

claude --debug

Troubleshooting

Common Issues

Server Not Found

Symptoms: Command not found errors, Server tools unavailable

Cause: Server not installed or not in PATH

Solution:

• Verify server installation
• Check PATH environment variable
• Install server globally or in project

Configuration Not Loaded

Symptoms: CLAUDE.md changes not recognized, Old server config used

Cause: CLAUDE.md file not in correct location or format

Solution:

• Ensure CLAUDE.md is in project root
• Verify markdown syntax is correct
• Restart Claude Code session

AgentRPC not appearing in Claude Code

Symptoms: Server not listed, Tools not available

Cause: Configuration or installation issue

Solution:

• Verify configuration syntax
• Check AgentRPC installation
• Restart Claude Code
• Check logs for error messages
