Implementation Reference

  • Handler function for 'check_install_content_updates' tool. Performs a POST request to the Palo Alto API endpoint '/Device/ContentUpdates' to check for and install content updates, then returns the JSON response as text content.
    case 'check_install_content_updates': {
        try {
            const response = await axios.post(
                `${API_BASE_URL}/Device/ContentUpdates`,
                {},
                {
                    headers: {
                        'X-PAN-KEY': API_KEY,
                        'Accept': 'application/json'
                    }
                }
            );
    
            return {
                content: [
                    {
                        type: 'text',
                        text: JSON.stringify(response.data, null, 2),
                    },
                ],
            };
        } catch (error) {
            const axiosError = error as AxiosError;
            throw new McpError(
                ErrorCode.InternalError,
                `Palo Alto API error: ${axiosError.message}`
            );
        }
    }
  • src/index.ts:58-65 (registration)
    Tool registration in the ListTools response, defining the tool name, description, and empty input schema.
    {
        name: 'check_install_content_updates',
        description: 'Automatically Check for and Install Content Updates',
        inputSchema: {
            type: 'object',
            properties: {},
        },
    },
  • Input schema for the 'check_install_content_updates' tool, which requires no parameters.
    inputSchema: {
        type: 'object',
        properties: {},
    },
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries full burden but offers minimal behavioral context. It mentions 'automatically' which suggests some automation, but doesn't disclose whether this requires specific permissions, what happens during the process, whether it's reversible, or any rate limits. For a tool that likely performs system changes, this is inadequate.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is perfectly concise - a single sentence that clearly states what the tool does. Every word earns its place, and it's front-loaded with the essential information. No wasted verbiage or unnecessary elaboration.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool that likely performs system updates (potentially destructive changes), the description is insufficient given no annotations and no output schema. It doesn't explain what 'content updates' means, what gets updated, potential risks, or what to expect after execution. The context signals show this is a parameterless tool, but the description doesn't provide enough operational context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has 0 parameters with 100% schema description coverage, so the baseline is 4. The description appropriately doesn't waste space discussing non-existent parameters, maintaining focus on the tool's purpose.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose with specific verbs ('check for and install') and resource ('content updates'), making it immediately understandable. However, it doesn't differentiate from sibling tools like 'upgrade_firewall' or 'upgrade_ha_firewalls_from_panorama' which might also involve updates, so it doesn't reach the highest clarity level.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites, timing considerations, or how it differs from sibling tools like 'upgrade_firewall' or 'run_operational_mode_command' that might also perform system updates.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
