visdemo-fusion-mcp

MCP server that connects Claude Desktop to the Visdemo Oracle Fusion Cloud instance (https://dabpqy.ds-fa.oraclepdemos.com/) via Basic Auth, exposing suppliers, purchase orders, invoices, and project costs as callable tools.

⚠️ Security notes (read first)

• No real credentials are committed here. .env is git-ignored; only .env.example (with placeholder values) is tracked. Fill in the real password locally, never in a commit.

• This repo will be public. Do not paste the real FUSION_PASSWORD into any file that gets pushed, including screenshots, issues, or commit messages. If it's ever committed, rotate the Oracle password immediately, even after removing it from history.

• If you're reusing an install command from another project that embeds a GitHub token in the URL (git+https://x-access-token:TOKEN@github.com/...), that token grants push/pull access to whatever repo it's scoped to. Don't reuse someone else's token — since this repo is public, you don't need any token at all to install from it (see below).

1. Local setup

git clone https://github.com/yedla26/visdemo-fusion-mcp.git
cd visdemo-fusion-mcp
python3 -m venv .venv && source .venv/bin/activate
pip install -r requirements.txt
cp .env.example .env
# edit .env and set FUSION_PASSWORD to the real value

2. Test the connection

python test_connection.py

Expected output on success:

Testing connection to https://dabpqy.ds-fa.oraclepdemos.com as PPM_IMPL ...
[OK] Authenticated successfully.

Common failures:

3. Create the public GitHub repo

I don't have GitHub write access from here, so create it yourself (one time):

Option A — web UI

1. Go to https://github.com/new

2. Owner: yedla26, Repository name: visdemo-fusion-mcp, Visibility: Public

3. Don't initialize with a README/license (this folder already has one)

4. Create repository, then from this folder:

   git init
   git add .
   git commit -m "Initial commit: Visdemo Fusion MCP server"
   git branch -M main
   git remote add origin https://github.com/yedla26/visdemo-fusion-mcp.git
   git push -u origin main

Option B — GitHub CLI (if gh is installed and authenticated):

gh repo create yedla26/visdemo-fusion-mcp --public --source=. --remote=origin --push

Before pushing, double check .env is NOT staged:

git status   # .env should not appear; only .env.example should

4. Connect it to Claude Desktop

Edit your Claude Desktop config (claude_desktop_config.json) and add an entry. Two ways to run it:

A. Run from a local clone (works immediately, no publish step needed):

{
  "mcpServers": {
    "visdemo-fusion-mcp": {
      "command": "uv",
      "args": ["--directory", "/absolute/path/to/visdemo-fusion-mcp", "run", "python", "server.py"],
      "env": {
        "FUSION_BASE_URL": "https://dabpqy.ds-fa.oraclepdemos.com",
        "FUSION_USER": "PPM_IMPL",
        "FUSION_PASSWORD": "REPLACE_WITH_REAL_PASSWORD",
        "FUSION_MAX_ROWS": "100",
        "LOG_LEVEL": "INFO"
      }
    }
  }
}

See claude_desktop_config.example.json for a copy of this.

B. Run straight from GitHub via uvx (once step 3 is pushed) — since the repo is public, no access token is needed in the URL at all:

{
  "mcpServers": {
    "visdemo-fusion-mcp": {
      "command": "uvx",
      "args": ["--from", "git+https://github.com/yedla26/visdemo-fusion-mcp", "visdemo-fusion-mcp"],
      "env": {
        "FUSION_BASE_URL": "https://dabpqy.ds-fa.oraclepdemos.com",
        "FUSION_USER": "PPM_IMPL",
        "FUSION_PASSWORD": "REPLACE_WITH_REAL_PASSWORD",
        "FUSION_MAX_ROWS": "100",
        "LOG_LEVEL": "INFO",
        "UV_LINK_MODE": "copy"
      }
    }
  }
}

Restart Claude Desktop after editing the config. Then ask Claude to run the test_connection tool to confirm it's wired up correctly.
