Business Central MCP Server Configuration

The bc-al-dev plugin includes an MCP server that connects to Business Central. Configure it using either:

Option 1: Per-Project Settings (Recommended for Teams)

Create .claude/settings.json for shared config (committed to git):

{
  "pluginConfigs": {
    "bc-al-dev@expressluck.sub-business-central.hq-agent-plugin-marketplace": {
      "options": {
        "bcTenantId": "your-tenant-id-guid",
        "bcEnvironmentName": "Production",
        "bcCompany": "CRONUS USA, Inc."
      }
    }
  }
}

Create .claude/settings.local.json for secrets (add to .gitignore):

{
  "pluginConfigs": {
    "bc-al-dev@expressluck.sub-business-central.hq-agent-plugin-marketplace": {
      "options": {
        "bcClientId": "your-app-client-id",
        "bcClientSecret": "your-client-secret"
      }
    }
  }
}

Team members clone repo and add their own secrets locally.

Option 2: Environment Variables (Global)

Add to ~/.claude/settings.json under env:

{
  "env": {
    "BC_TENANT_ID": "your-tenant-id-guid",
    "BC_ENVIRONMENT_NAME": "Production",
    "BC_COMPANY": "CRONUS USA, Inc.",
    "BC_CLIENT_ID": "your-app-client-id",
    "BC_CLIENT_SECRET": "your-client-secret",
    "BC_CONFIGURATION_NAME": "optional-config-name"
  }
}

Option 3: Plugin User Config

Run the plugin config command:

claude plugin config bc-al-dev@expressluck.sub-business-central.hq-agent-plugin-marketplace

This prompts for each configuration value. Sensitive values (client secret) are stored securely in system keychain.
