Setting up the iDNA Applications Companion

Overview

The iDNA Applications Companion is an AI-assistant plugin for HCL Notes/Domino estate analysis: usage, modernization, source-code remediation and application lifecycle. It adds a curated knowledge wiki and analysis guidance to your AI client and, once connected to the MCP server of your iDNA Applications appliance, answers from your live iDNA data.

The Companion consists of two parts, which every user sets up on each machine:

The plugin: the knowledge wiki, the "idna-wikilookup" skill and the Companion's operating instructions. The plugin also works on its own. without a connection to iDNA. It answers from the wiki only (restricted wiki mode) and says so.
It is installed from panagenda's plugin marketplace on GitHub:
- https://github.com/panagenda/idna-companion
The MCP connection: connects the AI client to your iDNA appliance for live data. It requires that your iDNA administrator has enabled the MCP server (see Setting up the MCP Server in iDNA Applications).

Supported Clients

Not supported: claude.ai Chat, and the Chat mode of the Claude desktop app. The Companion needs its plugin files next to its skill, and they are not available there. In the Claude desktop app, use Cowork or Code.

Prerequisites

Client: one of the supported clients, installed and signed in.
Installation source: access to github.com, or an offline copy of the plugin (see Machines Without Access to github.com).
License: installing or using the plugin is subject to its license, which is part of the plugin and of the repository on GitHub.
For live data:
- the MCP server is enabled on your iDNA appliance (iDNA Applications 3.5.0 or later),
- your iDNA user has the MCP role (ask your iDNA administrator),
- your machine reaches the appliance over HTTPS (through VPN where applicable),
- a personal MCP token (see the next section).

In all examples below, replace <your iDNA host> with the host name of your iDNA appliance (the one in the address of the iDNA web interface) and <your token> with your MCP token.

Getting Your MCP Token

In the iDNA web interface, click your user name at the top right and select [MCP Tokens]. Enter a label that tells you where the token is used (for example laptop-claude), check the expiry date and click [Create token]. Copy the token right away: it is shown only once. Screenshots and details are in Setting up the MCP Server in iDNA Applications, Step 4.

Note: create one token per machine or client, so that each can be revoked on its own. The clients store the token in plain text, in their configuration or, for OpenAI ChatGPT/Codex, in an environment variable; treat it like a password and do not share it.

Cowork and Claude Desktop

Install the Plugin

In the Claude desktop app, open Cowork and select [Customize].
Note: install the plugin here, not in the Code tab. Plugins installed through Customize are available in Cowork and Code; plugins installed in the Code tab are available in Code only.
Go to [Plugins] and select [+ Add] → [Add marketplace].
Enter https://github.com/panagenda/idna-companion, select it and confirm with [Sync].
The marketplace now lists the iDNA Applications Companion. Click [Add] to install it.

Connect to the MCP Server

The Claude desktop app connects to the MCP server from your machine, through the helper tool mcp-remote. Your iDNA data therefore does not pass through a connection from the Claude cloud to your appliance. The setup is manual, and it requires Node.js.

Install Node.js from https://nodejs.org/en/download/ if it is not installed yet. To check, run npm -v in a command prompt.
Install mcp-remote:
```
npm install -g mcp-remote
```
To check, run mcp-remote test. The command ends with an error like code: 'ERR_INVALID_URL', input: 'test', which is expected: it shows that mcp-remote is installed.
Open the configuration: on Windows, the menu (three horizontal bars at the top left) → [File] → [Settings] → [Developer] → [Edit Config]; on macOS, [Claude] → [Settings] → [Developer] → [Edit Config]. This opens the file claude_desktop_config.json (or the folder that contains it); open the file in a text editor.
Screenshot needed

Claude desktop app, Settings → Developer, with the [Edit Config] button marked. No MCP server entries with real host names or tokens visible.
Exit Claude completely before you edit the file: closing the window is not enough. On Windows, right-click the Claude icon in the notification area of the taskbar and select [Exit]; on macOS, quit Claude.
Add the iDNA Applications entry under "mcpServers". If the file already contains other settings, keep them and add only the "iDNA Applications" block; if there is no "mcpServers" section yet, add it. Make sure the file remains valid JSON (commas, braces).
```
{
  "mcpServers": {
    "iDNA Applications": {
      "command": "mcp-remote",
      "args": [
        "https://<your iDNA host>/mcp",
        "--header",
        "Authorization: Bearer <your token>"
      ]
    }
  }
}
```
Save the file and start Claude again. In [Settings] → [Developer], the "iDNA Applications" server is now listed as running.
Screenshot needed

Claude desktop app, Settings → Developer: the "iDNA Applications" server with the status "running", the command mcp-remote and its arguments, with the host replaced by an example host and the token blurred.

Cowork and the Code tab of the Claude desktop app both use this connection.

Check the Connection

Ask a question in Cowork, for example "What are my most used Notes applications?". In the Context panel on the right, the answer lists "iDNA Applications" under Connectors and "idna-wikilookup" under Skills.

Claude Code

Install the Plugin

claude plugin marketplace add panagenda/idna-companion
claude plugin install idna-companion@panagenda

Inside a Claude Code session, /plugin marketplace add panagenda/idna-companion and /plugin install idna-companion@panagenda do the same.

Connect to the MCP Server

claude mcp add --transport http --scope user "iDNA Applications" https://<your iDNA host>/mcp --header "Authorization: Bearer <your token>"

--scope user makes the server available in all your projects; without it, the server is only available in the current project.

Check the Connection

Run claude mcp list: "iDNA Applications" shows as connected. Inside a session, /mcp shows the same. Start a new session after installing the plugin or adding the server.

GitHub Copilot App

Install the Plugin

Open [Customize] in the left bar and select [+ Add ▾] → [Manage marketplaces...].
Under Source, enter https://github.com/panagenda/idna-companion and click [Add].
The dialog confirms "Added panagenda marketplace" and lists the panagenda marketplace. Close the dialog.
Under Plugins, select [+ Add plugin] → [Browse all plugins].
Search for idna and click [+ Install] next to idna-companion.
Under [Installed], the plugin is now listed under Plugins with "Marketplace: panagenda", switched on.

Connect to the MCP Server

In [Customize], select [+ Add ▾] → [MCP Server...] (see the previous screenshot), or click [+ Add server] under MCP Servers.
Enter:
- Server name: iDNA Applications
- Server type: HTTP
- URL: https://<your iDNA host>/mcp
- Headers: Name Authorization, Value Bearer <your token>
Leave OAuth Client ID and Timeout empty, and click [Save].

Check the Connection

Under MCP Servers, "iDNA Applications" is listed with a green check mark and switched on.

Ask an iDNA or Notes question in any chat, for example "What are my most used Notes applications?". The Companion's skill activates on such questions automatically. In a connected session, the "idna-wikilookup" skill loads and a "Get Idna Session" tool call succeeds.

GitHub Copilot CLI

Install the Plugin

copilot plugin marketplace add panagenda/idna-companion
copilot plugin install idna-companion@panagenda

Connect to the MCP Server

Add the server to ~/.copilot/mcp-config.json (keep any other entries in the file):

{
  "mcpServers": {
    "iDNA Applications": {
      "type": "http",
      "url": "https://<your iDNA host>/mcp",
      "headers": {
        "Authorization": "Bearer <your token>"
      }
    }
  }
}

Note: the Copilot App on Windows and a Copilot CLI inside WSL do not share their configuration. Each needs its own plugin installation and MCP entry.

Check the Connection

Ask an iDNA or Notes question in a new session. In a connected session, the "idna-wikilookup" skill loads and a "Get Idna Session" tool call succeeds.

OpenAI ChatGPT/Codex

This section describes the OpenAI desktop app. For the Codex command line, see OpenAI Codex CLI.

Install the Plugin

Open [Customize] in the left bar, go to [Plugins] and select [Add ▾] → [Add a marketplace].
Under Source, enter https://github.com/panagenda/idna-companion. Leave Git ref and Sparse paths empty and click [Add marketplace].
In the [Personal] tab, the panagenda marketplace now lists idna-companion. Click [+] to install it.
The app confirms the installation, and the plugin's page lists the skill "Idna Wikilookup".

Connect to the MCP Server

The app reads your token from an environment variable, so the token is not stored in the app's configuration.

Store your token in a user environment variable named IDNA_MCP_TOKEN. On Windows: search the Start menu for "environment variables", open "Edit environment variables for your account", click [New...] under User variables, enter IDNA_MCP_TOKEN as the name and your token as the value, and confirm with [OK].
Quit the app and start it again. It reads environment variables only at startup.
Open the settings, select [Plugins] under Integrations and the [MCPs] tab, then select [Add ▾] → [Add MCP server].
Enter:
- Name: iDNA Applications
- Type: Streamable HTTP
- URL: https://<your iDNA host>/mcp
- Bearer token env var: IDNA_MCP_TOKEN (the name of the variable, not the token)
Leave Headers and Headers from environment variables empty, and click [Save].

When you replace your token, update the variable and restart the app; the MCP server entry stays as it is.

Check the Connection

The MCPs tab lists "iDNA Applications" under Servers, switched on. Start a new chat and ask an iDNA or Notes question, for example "What are my most used Notes applications?". In a connected session, the "Idna Wikilookup" skill loads and a "Get Idna Session" tool call succeeds.

Screenshot needed

OpenAI ChatGPT/Codex, Settings → Plugins → MCPs: "iDNA Applications" listed under Servers and switched on.

OpenAI Codex CLI

Install the Plugin

codex plugin marketplace add panagenda/idna-companion

Then install "idna-companion" from the marketplace: type /plugins in the Codex terminal interface.

Connect to the MCP Server

Store your token in the user environment variable IDNA_MCP_TOKEN as described under OpenAI ChatGPT/Codex, then add the server to ~/.codex/config.toml:

[mcp_servers.idna_applications]
url = "https://<your iDNA host>/mcp"
bearer_token_env_var = "IDNA_MCP_TOKEN"

Open a new terminal afterwards, so that Codex sees the variable.

Check the Connection

Run codex mcp list, or type /mcp in the Codex terminal interface: "idna_applications" is listed.

Machines Without Access to github.com

Supported for the GitHub Copilot App, the GitHub Copilot CLI and Claude Code.

On a machine that can reach GitHub, download the archive of a release: https://github.com/panagenda/idna-companion/archive/refs/tags/v<version>.zip.
On the target machine, unzip it. This creates a folder idna-companion-<version>. Copy that folder's contents into a fixed folder that stays in place, for example C:\panagenda\idna-companion-marketplace. The client may load the plugin from there, so do not delete or move it.
Register the fixed folder as a marketplace and install the plugin:
- GitHub Copilot App: [Manage marketplaces...] → the folder path as Source, then [Add plugin] → [Browse all plugins] → [Install] next to idna-companion.
- GitHub Copilot CLI: copilot plugin marketplace add <folder>, then copilot plugin install idna-companion@panagenda.
- Claude Code: claude plugin marketplace add <absolute folder path>, then claude plugin install idna-companion@panagenda.

To update, replace the fixed folder's contents with those of the new release, then refresh the marketplace and update the plugin as described under Updating. In the GitHub Copilot App, reinstall the plugin from the refreshed marketplace.

Updating

Marketplace installations receive new releases from the GitHub repository:

Cowork: the marketplace's [Update] action.
Claude Code: claude plugin marketplace update panagenda, then claude plugin update idna-companion@panagenda; restart the session to apply.
GitHub Copilot CLI: copilot plugin marketplace update panagenda, then copilot plugin update idna-companion@panagenda.
GitHub Copilot App: [Update all] next to Plugins in [Customize].
Other clients: reinstall the plugin from the refreshed marketplace.

Each release is tagged v<version>; its commit message on GitHub says what changed.

Switching from an Earlier Installation

GitHub Copilot and Claude Code register a marketplace by its name, and panagenda's marketplace is named panagenda. If a marketplace named panagenda from another source is already registered (for example an earlier test installation or a zip folder), remove it and its plugin first:

GitHub Copilot CLI: copilot plugin marketplace remove panagenda --force (this also uninstalls its plugins).
Claude Code: claude plugin marketplace remove panagenda (this also removes its plugins).
Cowork and GitHub Copilot App: uninstall the Companion and remove the panagenda marketplace in the plugin settings.

Then install as described above, start a new session and check the plugin's version.

Choosing the AI Model

In GitHub Copilot and OpenAI ChatGPT/Codex, you choose the AI model per session. How reliably the Companion follows its restricted-mode rules (which analysis paths it offers and explains) depends on the model: the most capable models follow them best, smaller models less reliably. Organizations that operate MCP in restricted mode should standardize on the strongest available model for Companion sessions. Access to the data itself is enforced by your iDNA appliance and does not depend on the model.

Troubleshooting

The Companion says that live iDNA tools are unavailable and answers in restricted wiki mode. The session has no working MCP connection. Possible causes: the MCP entry is missing on this machine, the token has expired or was revoked, there is no network path to the appliance (VPN), or the client did not load the tools for this session (start a new session).
The server is listed but fails to connect. Check that the address ends in /mcp and that the token is still valid in [MCP Tokens]. An expired or revoked token is rejected; create a new one and update the client's configuration.
Claude desktop app: the server does not start. Check that Node.js and mcp-remote are installed (see above), and that Claude was exited completely before the configuration was edited. The logs are in %APPDATA%\Claude\logs\ (files mcp*.log) on Windows; [Settings] → [Developer] also offers [View logs].
OpenAI ChatGPT/Codex or Codex CLI: the server fails to connect after the token was set or replaced. The app and the CLI read IDNA_MCP_TOKEN only when they start: restart the app or open a new terminal. Check that the name of the variable matches exactly.
GitHub Copilot App on Windows: uninstalling or updating fails with "access denied". The App installs plugin files read-only and can fail to remove them. Clear the flag in PowerShell, then retry:
```
attrib -R /S /D "$env:USERPROFILE\.copilot\installed-plugins\*"
```

Ending access: delete the token in [MCP Tokens] in the iDNA web interface and remove the "iDNA Applications" entry from the client's configuration (for OpenAI ChatGPT/Codex and Codex CLI, also the IDNA_MCP_TOKEN variable).
