Oracle EPM Cloud MCP Server

Connect Claude AI (or any MCP-compatible client) to Oracle EPM Cloud via REST APIs.

What This Does

This MCP server gives AI agents the ability to interact with Oracle EPM Cloud. Instead of manually running Postman calls or EPM Automate commands, you can ask Claude to:

• "What applications are in my EPM environment?"
• "Show me the current substitution variables"
• "Run the Agg_AllData business rule"
• "Export Q1 revenue data for North America"
• "Roll the current month forward from Mar to Apr"

The server translates these natural language requests into Oracle EPM REST API calls.

Architecture

You (natural language) → Claude Desktop → MCP Protocol → This Server → Oracle EPM REST APIs → Your EPM Cloud

Quick Start (Mock Mode — No EPM Environment Needed)

Prerequisites

• Node.js 18+ installed (download)
• Claude Desktop installed (download)

Step 1: Download and install

# Clone or download this folder
cd oracle-epm-mcp-server
npm install

Step 2: Configure Claude Desktop

Open Claude Desktop → Settings → Developer → Edit Config

Add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "oracle-epm-cloud": {
      "command": "node",
      "args": ["/FULL/PATH/TO/oracle-epm-mcp-server/index.js"]
    }
  }
}

Replace /FULL/PATH/TO/ with the actual path on your machine.

Windows example:

{
  "mcpServers": {
    "oracle-epm-cloud": {
      "command": "node",
      "args": ["C:\\Users\\Fred\\oracle-epm-mcp-server\\index.js"]
    }
  }
}

Mac example:

{
  "mcpServers": {
    "oracle-epm-cloud": {
      "command": "node",
      "args": ["/Users/fred/oracle-epm-mcp-server/index.js"]
    }
  }
}

Step 3: Restart Claude Desktop

Quit Claude Desktop completely and reopen it. You should see the MCP tools icon (hammer) in the chat input area. Click it to verify "oracle-epm-cloud" is listed.

Step 4: Try it

Type in Claude Desktop:

"What EPM applications are available in my environment?"

Claude will use the list_applications tool and return the mock data.

Switching to Live Mode (Real EPM Environment)

When you have access to an Oracle EPM Cloud environment, set these environment variables in your Claude Desktop config:

{
  "mcpServers": {
    "oracle-epm-cloud": {
      "command": "node",
      "args": ["/FULL/PATH/TO/oracle-epm-mcp-server/index.js"],
      "env": {
        "EPM_MODE": "live",
        "EPM_BASE_URL": "https://epm-YOURDOMAIN.epm.REGION.oraclecloud.com",
        "EPM_USERNAME": "IDENTITYDOMAIN.your_username",
        "EPM_PASSWORD": "your_password",
        "EPM_APP_NAME": "Vision"
      }
    }
  }
}

That's it. Same 7 tools, but now hitting your real environment.

Authentication Note

The REST APIs use Basic Authentication. Your username format must be identitydomain.username — this is the #1 most common mistake. If you get 401 errors, check this first.

Accounts with multi-factor authentication (MFA) enabled cannot use Basic Auth. You would need OAuth 2.0 instead (not covered in this version).

Month-End Close Automation Example

Here's the sequence an AI agent would follow to automate a month-end close:

1. Check current period: get_substitution_variables → sees CurrMonth = "Mar"
2. Run aggregation: run_business_rule with "Agg_AllData"
3. Wait for completion: check_job_status with the returned job ID
4. Validate data: export_data_slice for Revenue, COGS, Net Income
5. Roll period forward: update_substitution_variable CurrMonth from "Mar" to "Apr"
6. Confirm: get_substitution_variables → verifies CurrMonth = "Apr"

This is the exact same workflow a finance team does manually each month — now executable through natural language.

Troubleshooting

Error	Cause	Fix
MCP tools not showing in Claude	Config path wrong	Check claude_desktop_config.json path is absolute
401 Unauthorized	Username format	Use identitydomain.username, not just username
403 Forbidden	Insufficient permissions	User needs EPM admin or appropriate role
Connection refused	Wrong URL	Check EPM_BASE_URL matches your environment
ETIMEDOUT	Network/firewall	Verify you can reach the EPM URL from your machine

What's Next

• OAuth 2.0 support — for environments with MFA enabled
• FCCS-specific tools — consolidation, intercompany elimination
• Data integration tools — file upload/download via Migration APIs
• Groovy rule execution — run Groovy scripts via REST API
