@vothlab/mcp-server

Official MCP (Model Context Protocol) server for vothlab.com — exposes vothlab's developer tools so any MCP-compatible LLM client (Claude Desktop, Claude Code, Cursor, etc.) can call them directly.

Tools

| Tool | Description | |---|---| | base64_encode / base64_decode | Base64 encode/decode with full Unicode support | | url_encode / url_decode | Percent-encoding encode/decode | | jwt_decode | Decode a JWT's header/payload/expiry (no signature verification) | | hash_generate | MD5 / SHA-1 / SHA-256 / SHA-384 / SHA-512 | | uuid_generate | Random UUID v4, batch + case options | | password_generate | Configurable strong password generator | | yaml_to_json / json_to_yaml | Bidirectional YAML ↔ JSON | | json_to_csv / csv_to_json | Bidirectional JSON ↔ CSV | | timestamp_convert | Epoch ↔ human-readable date, either direction, or "now" | | color_convert | HEX ↔ RGB ↔ HSL | | regex_test | Run a regex against text, return matches + capture groups | | text_diff | Line- or word-level diff between two texts |

All tools are free, deterministic, and run locally — no data leaves the machine running the server.

Install & run

Local (stdio), via Claude Code

claude mcp add vothlab -- npx -y @vothlab/mcp-server

Local (stdio), via Claude Desktop / other MCP clients

Add to your client's MCP config:

{
  "mcpServers": {
    "vothlab": {
      "command": "npx",
      "args": ["-y", "@vothlab/mcp-server"]
    }
  }
}

From source

npm install
npm run build
npm start        # runs dist/index.js over stdio
npm run inspect  # open the MCP Inspector against the built server

Development

npm run dev   # run src/index.ts directly with tsx, no build step

Publishing (npm)

npm run build
npm publish --access public

Roadmap

This is the free tier — deterministic, no external API calls. Planned: premium AI-powered tools (natural-language → regex/SQL, debug assistant, etc.) gated behind an API key tied to a vothlab subscription, served from the same MCP endpoint.
