ActiveDirectoryMCP - Enhanced Active Directory MCP Server

Independent Deployment (2026-10-04)

This project owns only the Active Directory MCP deployment. WinRM and M365 now live in sibling projects ../WinRM-MCP and ../Microsoft365-MCP, each with its own source, Dockerfile, Compose project, network and private configuration. The original vendor/winrm-mcp and vendor/ms365-mcp directories are preserved for rollback, excluded from the AD build context, and not used by the new launchers.

Build AD with docker compose build ad-mcp and launch stdio with .\start.ps1. Claude Desktop should point directly to this launcher, not the previous Node HTTP bridge. It creates a disposable container in the activedirectorymcp project, mounts only this project's ad-config read-only, publishes no port, and explicitly disables integrated WinRM. It neither starts nor stops the other MCP projects.

The existing optional ad-mcp-http endpoint on 127.0.0.1:8813 remains available and unchanged for other clients. docker compose down stops AD's project only. Do not use the historical remoting override when operating this separated setup. No directory account, permissions or credentials are changed by this migration.

A comprehensive Python-based Model Context Protocol (MCP) server for managing Active Directory environments through LDAP. This project provides powerful tools for user management, group operations, computer account management, organizational unit administration, and security auditing.

Optional read-only PowerShell remoting adds DC inventory, replication status, selected dcdiag checks, and GPO listing/reports through a restricted Windows JEA endpoint. See WinRM Diagnostics for deployment and limits. These tools are disabled by default; Windows endpoint setup is required.

🔍 Troubleshooting

✅ Recent Fixes (v0.1.0)

• LDAP3 Compatibility: Fixed TLS configuration compatibility with latest ldap3 library

• Test Suite: All 43 tests now passing successfully (100% success rate)

• Mock Issues: Resolved integration test mocking for error scenarios

• Security Config: Removed deprecated LDAP parameters for better compatibility

Common Issues

1. LDAP Connection Failed

   # Test connectivity
   ldapsearch -H ldap://dc.example.com -D "CN=user,DC=example,DC=com" -W -b "DC=example,DC=com" "(objectClass=domain)"

2. Permission Denied

   • Verify service account permissions

   • Check OU access rights

   • Ensure proper LDAP bind DN

3. SSL/TLS Issues

   # Test SSL connection
   openssl s_client -connect dc.example.com:636 -showcerts

4. Port Already in Use

   # Check port usage
   netstat -tlnp | grep 8813
   # Change port if needed
   HTTP_PORT=8814 ./start_http_server.sh

5. ⚠️ LLM Tool Limit Warning

   Some LLM models may experience issues with 40+ tools in context.
