Implementation Reference

  • The handler function for the 'open_automation_creator' tool. It returns a static ToolResult with a text message containing the URL to the SendGrid automation creator interface.
    handler: async (): Promise<ToolResult> => {
      return {
        content: [
          {
            type: "text",
            text: "Please open this URL in your browser to create a new automation:\nhttps://mc.sendgrid.com/automations/choose",
          },
        ],
      };
    },
  • The tool schema/configuration defining the title and description. No inputSchema is present as the tool takes no parameters.
    config: {
      title: "Open Automation Creator",
      description: "Open SendGrid automation creator in browser",
    },
  • Registration of automation tools (including open_automation_creator) by importing automationTools and spreading it into the allTools export, which likely registers all MCP tools.
    import { automationTools } from "./automations.js";
    import { campaignTools } from "./campaigns.js";
    import { contactTools } from "./contacts.js";
    import { mailTools } from "./mail.js";
    import { miscTools } from "./misc.js";
    import { statsTools } from "./stats.js";
    import { templateTools } from "./templates.js";
    
    export const allTools = {
      ...automationTools,
Behavior2/5

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

With no annotations provided, the description carries full burden for behavioral disclosure. It states the tool opens a browser interface but doesn't mention whether this requires authentication, what happens if the user lacks permissions, or if it launches a new tab/window. For a tool with potential side effects (browser interaction), this leaves significant 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 that communicates the core functionality without any wasted words. It's perfectly front-loaded with the essential information and contains no unnecessary elaboration.

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?

For a zero-parameter tool with no output schema, the description adequately covers the basic action. However, given that this likely interacts with a browser and has no annotations about safety or behavior, the description should ideally mention authentication requirements or what the opened interface allows the user to do next.

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 zero parameters, and schema description coverage is 100%, so no parameter documentation is needed. The description appropriately doesn't discuss parameters, earning a baseline score of 4 for this dimension.

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 action ('open') and target ('SendGrid automation creator in browser'), making the purpose immediately understandable. However, it doesn't distinguish itself from sibling tools like 'open_automation_editor' or 'open_segment_creator' beyond specifying which specific creator interface it opens.

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 about when to use this tool versus alternatives. The description doesn't mention prerequisites (like needing an existing automation to edit vs. create new), nor does it differentiate from similar 'open_' tools that might serve related purposes in the SendGrid ecosystem.

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