lit-forge MCP server

A stdio server that allows AI to directly call developer utilities from lit-forge.com via the Model Context Protocol (MCP).

It works with any MCP-compatible AI client, such as Claude Desktop, Claude Code, or Cursor.

Provided Tools (10 types)

Everything runs as pure functions (no external API required, stateless). It is useful for formatting JSON output by AI, debugging JWTs, or generating large amounts of UUIDs for test data.

Installation / Configuration

For Claude Desktop

Add the following to claude_desktop_config.json.

{
  "mcpServers": {
    "lit-forge": {
      "command": "npx",
      "args": ["-y", "lit-forge-mcp"]
    }
  }
}

Configuration file locations:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

• Windows: %APPDATA%\Claude\claude_desktop_config.json

For Claude Code

claude mcp add lit-forge -- npx -y lit-forge-mcp

For Cursor

Add the same JSON to ~/.cursor/mcp.json (or .cursor/mcp.json in the project root).

Local Development

git clone https://github.com/noblabs/lit-forge-mcp.git
cd lit-forge-mcp
npm install
npm run build
node dist/index.js   # stdio で起動

Verification

echo '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"smoke","version":"0.0.1"}}}
{"jsonrpc":"2.0","method":"notifications/initialized"}
{"jsonrpc":"2.0","id":2,"method":"tools/list"}' | node dist/index.js

If 10 tools appear in the tools/list response, it is successful.

Usage Examples

You can make requests to Claude like this:

• "Decode this JWT and show me the contents of the payload."

• "Convert name: foo\nlist: [1,2,3] to JSON."

• "Explain 0 9 * * 1-5 in English, and show the next 5 execution times in Asia/Tokyo."

• "Generate 20 UUID v7s for test data."

• "I want to parse email addresses with (\w+)@(\w+), try it with alice@example.com bob@test.jp."
