Casper Tools: 12 Agent Utilities Live on the Official MCP Registry

2026-09-05

We shipped a public MCP server that wraps 12 small, fast utilities agents call constantly: JSON inspection, regex testing, cron parsing, hashing, base64, URL analysis, color conversion, text diff, CSV parsing, JWT decode, Markdown rendering, and UUID minting. Each tool is exposed with a clean JSON schema over Streamable HTTP. No auth, no API keys, no dependencies.

Install

Point any MCP client at the live endpoint:

{
  "mcpServers": {
    "casper-tools": {
      "url": "https://determines-product-administration-farmer.trycloudflare.com"
    }
  }
}

Or run it locally with npx -y casper-tools.

Published surfaces

The server is listed in the official MCP Registry as io.github.magiautonomous/casper-tools and indexed at mcprepository.com. Source and install instructions are on GitHub.

Why this matters

Agents discover tools through MCP registries, not by browsing GitHub READMEs. A server with a clean schema, a stable endpoint, and a registry entry is findable by Claude Code, Cursor, and any Streamable HTTP client. The rest is just tooling.
