Implement clean Moqui-centric MCP v2.0 using built-in JSON-RPC 

- Replace custom REST API with Moqui's native /rpc/json endpoint
- Implement MCP methods as standard Moqui services with allow-remote='true'
- Remove unnecessary custom layers (webapp, screens, custom JSON-RPC handler)
- Direct service-to-tool mapping for maximum simplicity
- Leverage Moqui's built-in authentication, permissions, and audit logging
- Comprehensive client examples for Python, JavaScript, and cURL
- Complete documentation with architecture overview and usage patterns

Key Changes:
- service/McpServices.xml: MCP methods as standard Moqui services
- component.xml: Minimal configuration, no custom webapp
- AGENTS.md: Updated for Moqui-centric approach
- entity/, data/: Minimal extensions, leverage built-in entities
- Removed: mcp.rest.xml, screen/ directory (unnecessary complexity)

This demonstrates the power of Moqui's built-in JSON-RPC support
for clean, maintainable MCP integration.

1 # Moqui MCP v2.0 Server Guide
2
3 This guide explains how to interact with Moqui MCP v2.0 server for AI-Moqui integration using Model Context Protocol (MCP) and Moqui's built-in JSON-RPC support.
4
5 ## Repository Status
6
7 **moqui-mcp-2** is a **standalone component with its own git repository**. It uses Moqui's native JSON-RPC framework for maximum compatibility and minimal complexity.
8
9 - **Repository**: Independent git repository
10 - **Integration**: Included as plain directory in moqui-opencode
11 - **Version**: v2.0.0 (clean MCP implementation)
12 - **Approach**: Moqui-centric using built-in JSON-RPC support
13
14 ## Architecture Overview

26 ## MCP Implementation Strategy
27
28 ### **Moqui-Centric Design**
29 - ✅ **Built-in JSON-RPC**: Uses Moqui's `/rpc/json` endpoint
30 - ✅ **Standard Services**: MCP methods as regular Moqui services
31 - ✅ **Native Authentication**: Leverages Moqui's user authentication
32 - ✅ **Direct Integration**: No custom layers or abstractions
33 - ✅ **Audit Logging**: Uses Moqui's ArtifactHit framework
34
35 ### **MCP Method Mapping**
36 ```
37 MCP Method → Moqui Service
38 initialize → org.moqui.mcp.McpServices.mcp#Initialize
39 tools/list → org.moqui.mcp.McpServices.mcp#ToolsList
40 tools/call → org.moqui.mcp.McpServices.mcp#ToolsCall
41 resources/list → org.moqui.mcp.McpServices.mcp#ResourcesList
42 resources/read → org.moqui.mcp.McpServices.mcp#ResourcesRead
43 ping → org.moqui.mcp.McpServices.mcp#Ping
44 ```
45
46 ## JSON-RPC Endpoint
47
48 ### **Moqui Built-in Endpoint**
49 ```
50 POST /rpc/json
51 - Moqui's native JSON-RPC 2.0 endpoint
52 - Handles all services with allow-remote="true"
53 - Built-in authentication and audit logging
54 ```
55
56 ### **JSON-RPC Request Format**
57 ```json
58 {
59 "jsonrpc": "2.0",
60 "id": "unique_request_id",
61 "method": "org.moqui.mcp.McpServices.mcp#Initialize",
62 "params": {

299
300 ## Security and Permissions
301
302 ### **Authentication**
303 - Uses Moqui's built-in user authentication
304 - Pass credentials via standard JSON-RPC `authUsername` and `authPassword` parameters
305 - Or use existing session via Moqui's web session
306
307 ### **Authorization**
308 - All MCP services require `authenticate="true"`
309 - Tool access controlled by Moqui's service permissions
310 - Entity access controlled by Moqui's entity permissions
311 - Audit logging via Moqui's ArtifactHit framework
312
313 ### **Permission Setup**
314 ```xml
315 <!-- MCP User Group -->
316 <moqui.security.UserGroup userGroupId="McpUser" description="MCP Server Users"/>
317
318 <!-- MCP Service Permissions -->
319 <moqui.security.ArtifactAuthz userGroupId="McpUser"
320 artifactGroupId="McpServices"
321 authzTypeEnumId="AUTHZT_ALLOW"
322 authzActionEnumId="AUTHZA_ALL"/>
323 ```
324
325 ## Development and Testing
326
327 ### **Local Development**
328 1. Start Moqui with moqui-mcp-2 component
329 2. Test with JSON-RPC client examples above
330 3. Check Moqui logs for debugging
331 4. Monitor ArtifactHit records for audit trail
332
333 ### **Service Discovery**
334 - All Moqui services automatically available as MCP tools
335 - Filtered by user permissions
336 - Service parameters converted to JSON Schema
337 - Service descriptions used for tool descriptions
338
339 ### **Entity Access**
340 - All Moqui entities automatically available as MCP resources
341 - Format: `entity://EntityName`
342 - Filtered by entity VIEW permissions
343 - Limited to 100 records per request
344
345 ## Error Handling
346
347 ### **JSON-RPC Error Responses**
348 ```json
349 {
350 "jsonrpc": "2.0",
351 "id": "req_001",
352 "error": {
353 "code": -32601,
354 "message": "Method not found"
355 }
356 }
357 ```
358
359 ### **Common Error Codes**
360 - `-32600`: Invalid Request (malformed JSON-RPC)
361 - `-32601`: Method not found
362 - `-32602`: Invalid params
363 - `-32603`: Internal error (service execution failed)
364
365 ### **Service-Level Errors**
366 - Permission denied throws Exception with message
367 - Invalid service name throws Exception
368 - Entity access violations throw Exception
369 - All errors logged to Moqui error system
370
371 ## Monitoring and Debugging
372
373 ### **Audit Trail**
374 - All MCP calls logged to `moqui.server.ArtifactHit`
375 - Track user, service, parameters, execution time
376 - Monitor success/failure rates
377 - Debug via Moqui's built-in monitoring tools
378
379 ### **Performance Metrics**
380 - Service execution time tracked
381 - Response size monitored
382 - Error rates captured
383 - User activity patterns available
384

386
