MCP Server

MCP Server

Akeeba Panopticon includes an optional Model Context Protocol (MCP) server. It lets AI agents and chatbots — such as Claude Code, Claude Desktop, Codex, Cursor, VS Code, or JetBrains IDEs — drive Panopticon using the same operations as the JSON API, so you can ask an assistant things like “which of my sites have pending updates?” or “refresh site 12 and tell me if its backup is healthy”.

Important

Minimum version: the MCP server is available in Akeeba Panopticon 2.2.0 and later.

The MCP server is disabled by default. You must enable it, and every request must authenticate with a Panopticon API token. An AI agent can only ever see and do what the token's owner could do through the JSON API.

Enabling the MCP server

1. Log into Panopticon as a Super User.
2. Go to System Configuration → Security → MCP Server.
3. Turn on Enable the MCP server and save.

You can also enable it from the command line or by setting the mcp_enabled configuration option to true (see Configuration parameters).

While the server is disabled the endpoint responds as if it does not exist (HTTP 404).

Endpoint URL

The endpoint is:

https://panopticon.example.com/index.php/mcp

This form works on every server, with or without URL rewriting, so it is the one to use in the AI-tool configuration examples below.

If your server rewrites URLs — Apache with the shipped .htaccess (which includes the required rewrite rule), or an equivalent rule on Nginx/IIS — you can use the shorter form instead:

https://panopticon.example.com/index.php/mcp

Important

The short /mcp form needs a rewrite rule. The shipped htaccess.txt provides it, but you must rename that file to .htaccess (see The .htaccess file). Without it, /mcp returns a plain 404 and you must use the /index.php/mcp form. This rewrite rule was added in Panopticon 2.2.1; on 2.2.0 the /mcp form does not work even with the .htaccess — use /index.php/mcp.

Both forms route to the same server. The MCP server implements the Streamable HTTP transport in stateless mode: each request is self-contained and authenticated by a static HTTP header, so there is no session handshake to manage.

Authentication

Every request must carry a Panopticon API token in a standard HTTP Bearer Authorization header:

Authorization: Bearer YOUR_API_TOKEN

To mint a token, log into Panopticon, click your name (top-right) → API Tokens, and create one. The token inherits your account's permissions. You can also restrict a token to specific scopes (e.g. read-only) — the MCP server honours those scopes exactly like the JSON API does. See API Overview for details on tokens and scopes.

Tip

Treat an API token like a password. Anyone holding it can use the MCP server with your account's permissions. Prefer a dedicated, least-privilege token (restricted scopes, and an account that only has access to the sites you want the assistant to manage).

Important

Many web server / PHP combinations strip the Authorization header before it reaches PHP, which makes every request fail with a 401 even when the token is correct. The shipped .htaccess handles this for Apache; Nginx and IIS need a small amount of configuration. See The .htaccess file for the exact directives. If you cannot forward the header at all, use the _panopticon_token query-parameter fallback described in the AI-tool setup notes below.

Security model

The MCP server is designed so that an AI agent can never exceed the boundaries of the token it uses:

• Same permissions as the API. Every tool enforces the same access control as the equivalent API endpoint. A user who can only access sites A and B will not even see that sites C and D exist when listing sites.
• Token scopes apply. A tool is only offered if the token grants the scope that the matching API endpoint requires (for example, the schedule_cms_update tool needs the sites:cms-update scope). A token with no explicit scopes is treated as granting all scopes, exactly as in the API.
• Secrets are not exposed. Unlike the raw JSON API, MCP tools deliberately omit stored secrets (such as extension download keys and connection credentials) from their output, so they are never fed into an AI model's context.

Controlling which tools are available

There are two layers of control over the set of tools the MCP server offers, on top of the per-user permissions above.

1. Globally disabled tools (the kill-switch). In System Configuration → Security → MCP Server, the Globally disabled tools field accepts a comma-separated list of tool names that are never exposed to anyone, regardless of user, token, or group. For example, add get_sysconfig to keep system configuration entirely out of MCP. This list always wins.

2. Per-user-group disabled tools. When editing a user group, the Disabled MCP tools field lets a Super User deny specific tools to members of that group.

Important

ALLOW wins for per-group restrictions

When a user belongs to several groups, a tool is denied only if every one of their groups disables it. Being granted a tool by any group overrides being denied it by another group.

This is the opposite of Joomla's “deny wins” access control. It is a deliberate convention over configuration choice: tools stay available unless they are universally restricted. If you need an absolute block, use the global Globally disabled tools kill-switch described above, which always takes precedence.

Available tools

Tool	What it does	Required scope	Super User only

get_site	Get a single site's details	sites:read	no
get_site_status	Health summary for a site (CMS/PHP/extensions/backup)	sites:read	no
list_site_extensions	List a site's extensions/plugins and update state	sites:extensions	no
list_tasks	List scheduled tasks (others must pass a site_id they administer)	tasks:read	no

refresh_site	Refresh a site's information now	sites:refresh	no
schedule_cms_update	Schedule a CMS core update for a site	sites:cms-update	no
cancel_cms_update	Cancel a scheduled CMS update	sites:cms-update	no
schedule_extension_update	Schedule an extension/plugin update	sites:extensions	no
cancel_extension_update	Cancel a queued extension/plugin update	sites:extensions	no

Setting up the MCP server in AI tools

All of the coding tools below support Streamable HTTP MCP servers with a static HTTP header. The configuration key for the server URL is url for every tool except Antigravity (which uses serverUrl) and Qwen Code (which uses httpUrl).

In every example, replace https://panopticon.example.com/index.php/mcp with your endpoint and YOUR_API_TOKEN with your token. The examples use the universal /index.php/mcp form; if your server has the rewrite rule (Apache with the shipped .htaccess), you can shorten it to /mcp.

Claude Code

Use the CLI to add the server:

claude mcp add --transport http panopticon https://panopticon.example.com/index.php/mcp \
  --header "Authorization: Bearer YOUR_API_TOKEN"

Claude Desktop

Open Settings → Connectors → Add custom connector, give it a name (e.g. Panopticon), and set the URL to your endpoint. If your build of Claude Desktop lets you add request headers, add Authorization: Bearer YOUR_API_TOKEN. Otherwise, append the token as a query parameter instead (…/index.php/mcp?_panopticon_token=YOUR_API_TOKEN), which Panopticon also accepts.

Important

When you pass the token in the _panopticon_token query parameter you must URL-encode it. API tokens are Base64 and routinely contain +, / and =, which have special meaning in a URL — an unencoded + in particular is decoded to a space and corrupts the token. Most clients URL-encode query parameters for you; if you are building the URL by hand, encode the token first. Prefer the Authorization header in production: the query parameter also leaks the token into server access logs and Referer headers.

Codex CLI

Edit ~/.codex/config.toml:

[mcp_servers.panopticon]
url = "https://panopticon.example.com/index.php/mcp"

[mcp_servers.panopticon.http_headers]
Authorization = "Bearer YOUR_API_TOKEN"

Codex Desktop

In Codex Desktop's MCP settings, add a new server of type Streamable HTTP (or Remote), set the URL to your endpoint, and add an Authorization: Bearer YOUR_API_TOKEN header.

Qwen Code

Qwen Code uses the key httpUrl (not url). Edit ~/.qwen/settings.json:

{
  "mcpServers": {
    "panopticon": {
      "httpUrl": "https://panopticon.example.com/index.php/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_TOKEN"
      }
    }
  }
}

Mistral Vibe (formerly Le Chat)

In Mistral's tool/connector settings, add a custom MCP connector pointing at your endpoint URL and add an Authorization: Bearer YOUR_API_TOKEN header.

OpenHands

Add the server to your OpenHands MCP configuration:

{
  "mcpServers": {
    "panopticon": {
      "url": "https://panopticon.example.com/index.php/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_TOKEN"
      }
    }
  }
}

Antigravity

Antigravity uses the key serverUrl (not url):

{
  "mcpServers": {
    "panopticon": {
      "serverUrl": "https://panopticon.example.com/index.php/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_TOKEN"
      }
    }
  }
}

VS Code

Create .mcp.json in your workspace (or use MCP: Add Server from the Command Palette):

{
  "servers": {
    "panopticon": {
      "type": "http",
      "url": "https://panopticon.example.com/index.php/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_TOKEN"
      }
    }
  }
}

Cursor

Edit ~/.cursor/mcp.json (global) or .cursor/mcp.json (per-project):

{
  "mcpServers": {
    "panopticon": {
      "url": "https://panopticon.example.com/index.php/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_TOKEN"
      }
    }
  }
}

PhpStorm (and other JetBrains IDEs)

In Settings → Tools → AI Assistant → Model Context Protocol (MCP), add a server. Choose the HTTP / SSE type, set the URL to your endpoint, and add an Authorization: Bearer YOUR_API_TOKEN header. (You can also paste the JSON form with a url key and a headers object.)

A note on ChatGPT

The consumer ChatGPT app does not support adding a custom Streamable HTTP MCP server like this one. If you want to use Panopticon with OpenAI's tooling, install Codex Desktop (or the Codex CLI) on your computer and configure it as shown above.

Troubleshooting

• 404 with a JSON body ({"error":{"code":-32601,"message":"The MCP server is not enabled."}}): the MCP server is disabled. Enable it in System Configuration.
• 404 with a plain HTML page (your web server's own 404, no JSON): the request never reached Panopticon. You are almost certainly using the short /mcp form on a server without the rewrite rule. Switch to /index.php/mcp, or install the shipped .htaccess (Panopticon 2.2.1 or later — see The .htaccess file).
• 401 responses: the token is invalid, disabled, or expired — or the Authorization header is being stripped before it reaches PHP. Header stripping is the most common cause on shared hosting: verify your web server forwards the Authorization header (The .htaccess file). If you are using the _panopticon_token query parameter instead, make sure the token is URL-encoded.
• A tool you expected is missing from the list: check (1) the token's scopes, (2) whether the tool is in the Globally disabled tools list, (3) whether every one of your groups disables it, and (4) for Super-User-only tools, whether your account is a Super User.
• GET requests return 405: that is expected. The stateless server only accepts POST for JSON-RPC messages.
