Implementation Reference

  • Handler function that retrieves a specific segment from the Klaviyo API using the provided ID and returns the segment data or an error.
    async (params) => {
      try {
        const segment = await klaviyoClient.get(`/segments/${params.id}/`);
        return {
          content: [{ type: "text", text: JSON.stringify(segment, null, 2) }]
        };
      } catch (error) {
        return {
          content: [{ type: "text", text: `Error retrieving segment: ${error.message}` }],
          isError: true
        };
      }
    },
  • Zod schema for the tool input, requiring a string 'id' parameter for the segment ID.
    {
      id: z.string().describe("ID of the segment to retrieve")
    },
  • Registers the 'get_segment' tool on the MCP server with schema, handler, and description.
      "get_segment",
      {
        id: z.string().describe("ID of the segment to retrieve")
      },
      async (params) => {
        try {
          const segment = await klaviyoClient.get(`/segments/${params.id}/`);
          return {
            content: [{ type: "text", text: JSON.stringify(segment, null, 2) }]
          };
        } catch (error) {
          return {
            content: [{ type: "text", text: `Error retrieving segment: ${error.message}` }],
            isError: true
          };
        }
      },
      { description: "Get a specific segment from Klaviyo" }
    );
Behavior1/5

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

Tool has no description.

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

Conciseness1/5

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

Tool has no description.

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

Completeness1/5

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

Tool has no description.

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

Parameters1/5

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

Tool has no description.

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

Purpose1/5

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

Tool has no description.

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

Usage Guidelines1/5

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

Tool has no description.

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