Implementation Reference

  • The handler function for the 'open_csv_uploader' tool. It returns a ToolResult containing a text message with instructions and the URL to SendGrid's CSV contact upload page.
    handler: async (): Promise<ToolResult> => {
      return {
        content: [
          {
            type: "text",
            text: "Please open this URL in your browser to upload contacts via CSV:\nhttps://mc.sendgrid.com/contacts/import/upload-csv",
          },
        ],
      };
    },
  • The schema/config for the tool, defining its title and description. The tool takes no input parameters.
    config: {
      title: "Open CSV Uploader",
      description: "Open SendGrid CSV contact upload page in browser",
    },
  • Registration of the 'open_csv_uploader' tool within the contactTools object, which is aggregated into allTools and registered to the MCP server.
    open_csv_uploader: {
      config: {
        title: "Open CSV Uploader",
        description: "Open SendGrid CSV contact upload page in browser",
      },
      handler: async (): Promise<ToolResult> => {
        return {
          content: [
            {
              type: "text",
              text: "Please open this URL in your browser to upload contacts via CSV:\nhttps://mc.sendgrid.com/contacts/import/upload-csv",
            },
          ],
        };
      },
    },
  • src/index.ts:21-23 (registration)
    Final registration loop where all tools from allTools (including open_csv_uploader) are registered to the MCP server.
    for (const [name, tool] of Object.entries(allTools)) {
      server.registerTool(name, tool.config as any, tool.handler as any);
    }
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 the action but lacks details on what happens after the browser opens (e.g., whether authentication is required, if it opens a specific URL, or if it's platform-dependent). For a tool with zero annotation coverage, this leaves significant behavioral gaps.

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 front-loads the core action and resource, making it immediately understandable. Every word contributes to clarifying the tool's purpose.

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

Completeness3/5

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

Given the tool's simplicity (0 parameters, no output schema, no annotations), the description is adequate but minimal. It explains what the tool does but lacks context on prerequisites (e.g., browser availability, authentication state) or post-execution behavior. For a browser-launch tool, more guidance on expected outcomes would be helpful.

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 no parameter documentation is needed. The description doesn't mention parameters, which is appropriate. Baseline is 4 for zero-parameter tools, as no additional semantic value is required.

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

Purpose5/5

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

The description clearly states the specific action ('Open'), target resource ('SendGrid CSV contact upload page'), and mechanism ('in browser'). It distinguishes this tool from all sibling tools, which perform CRUD operations or analytics rather than browser navigation.

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

Usage Guidelines4/5

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

The description implies usage context by specifying 'in browser,' suggesting this tool launches a web interface rather than performing an API operation. However, it doesn't explicitly state when to use this versus alternatives like programmatic contact creation tools (e.g., create_contact, create_contact_with_lists).

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