add-mcp-primitive
Add new MCP primitives (Tool, Resource, Prompt). Use when asked to add a new tool, resource, or prompt to the MCP server.
Best use case
add-mcp-primitive is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
Add new MCP primitives (Tool, Resource, Prompt). Use when asked to add a new tool, resource, or prompt to the MCP server.
Teams using add-mcp-primitive should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# Adding MCP Primitives
## Tool
1. Create feature in `src/features/<name>/<name>.ts`
2. Create definition in `src/definitions/tools/<name>.ts`
3. Register in `src/definitions/tools/index.ts`
```typescript
// src/definitions/tools/my-tool.ts
import { defineTool } from "@/definitions/define.ts";
import { z } from "zod";
export const myTool = defineTool({
name: "my-tool",
title: "My Tool",
description: "What this tool does",
inputSchema: {
param: z.string().describe("Parameter description"),
},
handler: async ({ param }) => ({
content: [{ type: "text", text: "Result" }],
}),
});
```
## Resource
1. Create definition in `src/definitions/resources/<name>.ts`
2. Register in `src/definitions/resources/index.ts`
```typescript
// src/definitions/resources/my-resource.ts
import { defineResource } from "@/definitions/define.ts";
export const myResource = defineResource({
name: "my-resource",
uri: "my-resource://path",
title: "My Resource",
description: "What this resource provides",
mimeType: "text/plain",
handler: async (uri) => ({
contents: [{ uri: uri.href, mimeType: "text/plain", text: "Content" }],
}),
});
```
## Prompt
1. Create definition in `src/definitions/prompts/<name>.ts`
2. Register in `src/definitions/prompts/index.ts`
```typescript
// src/definitions/prompts/my-prompt.ts
import { definePrompt } from "@/definitions/define.ts";
import { z } from "zod";
export const myPrompt = definePrompt({
name: "my-prompt",
title: "My Prompt",
description: "What this prompt does",
argsSchema: {
topic: z.string().describe("Topic to discuss"),
},
handler: ({ topic }) => ({
messages: [
{ role: "user", content: { type: "text", text: `Discuss ${topic}` } },
],
}),
});
