AgentRPC + OpenSumi: Complete MCP Integration

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

When integrated with OpenSumi, 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 OpenSumi, 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 OpenSumi
• 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
• OpenSumi installed and configured
• Compatible operating system (Web (Browser-based), Electron Desktop, Container (Docker/K8s), Framework Integration)

Installation

Step 1: Install AgentRPC

Configuration

Step 2: Configure OpenSumi

1. Open OpenSumi settings
2. Navigate to MCP server configuration
3. Add AgentRPC server with appropriate settings
4. Save and restart if needed

Examples

Once configured, you can use AgentRPC in OpenSumi:

Multi-Language Microservices

undefined

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

Expected Result: undefined

Cross-Cloud Function Calls

undefined

Ask OpenSumi: "Execute distributed data processing across three clouds"

Expected Result: undefined

Kubernetes Function Registry

undefined

Ask OpenSumi: "List available functions in production cluster"

Expected Result: undefined

Testing Your Setup

1. Launch OpenSumi
2. Verify AgentRPC is available in the tools list

Troubleshooting

Common Issues

Dependency Installation Failures

Symptoms: Yarn/npm install errors, Missing packages, Version conflicts

Cause: Incompatible Node.js version or network issues

Solution:

• Ensure Node.js 16+ is installed
• Use yarn for standard installation, npm for lite version
• Clear package cache: yarn cache clean or npm cache clean --force
• Check network connectivity and proxy settings

Workspace Not Loading

Symptoms: Empty workspace, Files not showing, Permission errors

Cause: Incorrect workspace path or permissions

Solution:

• Verify MY_WORKSPACE environment variable is set correctly
• Check file system permissions for workspace directory
• Use absolute path for workspace location
• Default workspace is tools/workspace in repository

VSCode Extension Compatibility

Symptoms: Extension not loading, Extension errors, Missing features

Cause: Extension API incompatibility or missing dependencies

Solution:

• Verify extension is compatible with VSCode extension API used by OpenSumi
• Check extension documentation for known issues
• Try downloading extensions via yarn run download-extension
• Some extensions may require OpenSumi-specific adaptation

WebWorker Compilation Errors (Lite Version)

Symptoms: Compile-worker fails, Language service not working, Syntax highlighting broken

Cause: WebWorker build configuration issues

Solution:

• Run npm run compile-worker before starting
• Ensure all dependencies are installed correctly
• Check browser console for WebWorker loading errors
• Clear browser cache and rebuild

MCP Client Connection Failures

Symptoms: Cannot connect to MCP server, Tool discovery fails, MCP errors in console

Cause: MCP server not running or incorrect configuration

Solution:

• Verify MCP server is running and accessible
• Check MCP server URL in OpenSumi configuration
• Review MCP client integration code for errors
• Check browser/Electron console for detailed error messages

Electron App Not Starting

Symptoms: Electron window not opening, White screen, App crashes on launch

Cause: Electron build issues or IPC communication errors

Solution:

• Ensure Electron dependencies are installed correctly
• Check Electron version compatibility (15+)
• Review IPC communication setup in configuration
• Check Electron dev tools console for errors

AgentRPC not appearing in OpenSumi

Symptoms: Server not listed, Tools not available

Cause: Configuration or installation issue

Solution:

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