Implementation Reference

  • The MCP tool 'system_nodes_metrics' is defined here. It calls the RemnawaveClient's 'getNodesMetrics' method.
    server.tool(
        'system_nodes_metrics',
        'Get detailed node metrics',
        {},
        async () => {
            try {
                const result = await client.getNodesMetrics();
                return toolResult(result);
            } catch (e) {
                return toolError(e);
            }
        },
    );
  • This helper method in the RemnawaveClient executes the API request for node metrics.
    async getNodesMetrics() {
        return this.get(REST_API.SYSTEM.STATS.NODES_METRICS);
    }
Behavior2/5

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states a read operation ('Get') but doesn't cover aspects like authentication needs, rate limits, data format, or potential side effects. This is inadequate for a tool with zero annotation coverage.

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 a single, efficient sentence with no wasted words. It's front-loaded with the core action and resource, making it highly concise and well-structured for quick comprehension.

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?

Given no annotations and no output schema, the description is incomplete. It lacks details on what 'detailed node metrics' includes, how data is returned, or any behavioral context. For a tool in a system context with siblings, this leaves significant gaps.

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 input schema has 0 parameters with 100% coverage, so no parameter documentation is needed. The description doesn't add param info, which is appropriate here. Baseline is 4 for zero parameters, as it avoids redundancy.

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

Purpose3/5

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

The description 'Get detailed node metrics' states a clear verb ('Get') and resource ('node metrics'), but it's vague about what 'detailed' entails and doesn't distinguish from sibling tools like 'system_nodes_statistics' or 'system_health'. It avoids tautology but lacks specificity for differentiation.

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?

No guidance is provided on when to use this tool versus alternatives such as 'system_nodes_statistics' or 'system_health'. The description implies a context of retrieving metrics but offers no explicit when/when-not instructions or prerequisites, leaving usage unclear.

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