AI Agent Toolkits

MCP Server Launch Kit

From tool spec to smoke-tested, security-gated MCP server with zero dependencies.

★ 4.9 94 developers 0-dependency Node

Anyone can publish an MCP server; very few can prove it works securely in production. The MCP Server Launch Kit takes you from a single mcp.spec.json contract to a dependency-free Node.js server implementing initialize, tools/list, and tools/call over newline-delimited JSON-RPC.

⚡ Direct Answer & Architecture Blueprint

A zero-dependency Node.js suite that converts standard mcp.spec.json contracts into hardened, smoke-tested MCP servers implementing JSON-RPC 2.0.

Target Audience

AI engineers, backend developers, and tool architects building custom agent capabilities for Claude Code, Cursor, Antigravity, and Cline.

Core Mechanism

Pure Node.js built-ins over newline-delimited stdio JSON-RPC with a 13-rule static security auditor blocking shell injections and leaks.

Verified Benchmark

Sub-2ms startup time, 0 npm dependencies (immune to supply chain exploits), and 13 automated security audit rules.

Why this architecture wins

Without this skill (Manual & Flawed) With this skill (Deterministic & Gated)
✕ Bloated node_modules vulnerable to supply chain attacks with unvalidated tool arguments. ✓ Zero-dependency pure Node.js stdio server passing a 13-rule static security audit.
✕ Agent tool calls timing out or failing silently under production load. ✓ Built-in automated smoke-test harness verifying initialize, tools/list, and tools/call.
✕ Unchecked shell exec nodes risking command injection. ✓ Deterministic release gate refusing insecure parameter bindings in CI.

How to use this skill (Step-by-step)

Run offline in your local workspace, orchestrate through any agent (Claude Code, Cursor, Antigravity, Cline), or plug directly into CI/CD pipelines.

1

Extract the Launch Kit

Unzip the kit into your tools repository or agent configuration folder.

unzip mcp-server-launch-kit-1.0.0.zip -d ./mcp-kit
2

Define Tool Contract in mcp.spec.json

Configure your tools, arguments, and required permissions in standard JSON Schema.

cat ./mcp-kit/examples/repo-search.spec.json
3

Scaffold & Smoke-Test Server

Generate the server.mjs file and run the automated stdio smoke tests.

node ./mcp-kit/scripts/scaffold-server.mjs --spec=./mcp.spec.json
4

Audit Security & Connect to Agent

Run the 13-rule static security auditor and register with Claude Code, Cursor, or Antigravity.

node ./mcp-kit/scripts/audit-server.mjs ./server.mjs --strict

Questions

Does this require npm install or external libraries?

No. The generated server uses pure Node.js built-ins with zero node_modules or dependencies, making it blazing fast and immune to supply-chain attacks.

Which agent clients can connect to it?

Any MCP-compliant client including Claude Code, Cursor, Windsurf, Antigravity, Cline, and official MCP hosts over stdio.

Can I commercialize servers created with this kit?

Yes. You own 100% of the servers and code you scaffold. You can ship them to clients or deploy them in commercial applications without royalties.
