askell-mcp: Skill for Claude Code

.agents/skills/typescript-mcp-server-generator/SKILL.md

typescript-mcp-server-generator is a skill for Claude Code, Codex from Neschadin/askell-mcp. It costs 37 tokens per session (1,564 once invoked), scanned A, original, MIT.

A project generator for building Model Context Protocol (MCP) servers in TypeScript, using the MCP TypeScript SDK version 2. MCP lets an AI agent connect to tools and data provided by a server.

In plain words
What is it for?
Use it to start a TypeScript/Node.js MCP server with tools, resources, and the required configuration.
Why use it?
It removes the need to set up the project structure, packages, runtime settings, and server configuration by hand.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is Neschadin/askell-mcp's own configuration. It tells Claude Code and Codex how to work on askell-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything askell-mcp configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

typescript-mcp-server-generator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Generate TypeScript MCP Server

Create a complete Model Context Protocol (MCP) server in TypeScript using the MCP TypeScript SDK v2 with the following specifications:

Requirements

  1. Project Structure: Create a new TypeScript/Node.js project with proper directory structure
  2. NPM Packages: The v1 monolithic @modelcontextprotocol/sdk package is retired. Use the focused v2 packages:
    • @modelcontextprotocol/server — server implementation (stdio transport via the @modelcontextprotocol/server/stdio subpath)
    • @modelcontextprotocol/node — Node HTTP transport (NodeStreamableHTTPServerTransport), or a framework adapter: @modelcontextprotocol/express, @modelcontextprotocol/hono, @modelcontextprotocol/fastify — each adapter requires its peer framework to be installed alongside it (e.g. @modelcontextprotocol/express + express)
    • @modelcontextprotocol/core — shared protocol schemas (import *Schema constants from here, not from sdk/types.js)
    • zod@^4.2 — v2 requires Zod 4.2+; do not use zod@3
  3. Runtime: Node.js 20+ (v2 minimum); ESM-first with "type": "module" (a CommonJS build is also shipped, so require() works if needed)
  4. Server Type: Choose between HTTP (Streamable HTTP transport) or stdio-based server. SSE and WebSocket transports were removed in v2 — do not generate them.
  5. Tools: Create at least one useful tool with proper schema validation
  6. Error Handling: Include comprehensive error handling and validation

Implementation Details

Project Setup

  • Initialize with npm init and create package.json
  • Install dependencies: @modelcontextprotocol/server, zod@^4.2, and the transport package — @modelcontextprotocol/node for plain Node HTTP, or a framework adapter together with its peer framework (e.g. npm install @modelcontextprotocol/express express)
  • Configure TypeScript with ES modules: "type": "module" in package.json
  • Add dev dependencies: tsx or ts-node for development
  • Create proper .gitignore file

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
