Overview

AI-generated overview

A remote MCP server offering 19 zero-setup utilities for JSON, regex, cron, hash, base64, CSV, JWT, UUID, YAML, semver and time tasks.

What you can do
Format, validate and transform JSON, YAML and CSV data, including conversions between them and base64 encoding or decoding. Test and explain regular expressions, and parse or describe cron schedules. Compute hashes, generate UUIDs, and inspect or decode JWT tokens. Compare and bump semantic versions, and convert or calculate times.
When to use it
Useful when an assistant needs quick, stateless conversions or checks — formatting a JSON blob, testing a regex, decoding a JWT, generating a UUID or working out a cron schedule — without installing anything locally.
Requirements
A remote streamable HTTP endpoint; no package, account, API key or environment variable is declared. Network access to the hosted endpoint is required.
Before you install
The endpoint is a temporary-looking Cloudflare tunnel address, so availability may be unreliable. Data sent to the tools, including JWTs and other encoded content, goes to a third-party host; avoid sending secrets or sensitive tokens.

Installation

In SourceWeft

  1. Open Casper Tools in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.magiautonomous%2Fcasper-tools/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Score

25% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 daysRequired25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declaredRequired10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.

  • DescriptionRequired15 pts
  • Logo10 pts
  • Documentation15 pts

    Declare a GitHub repository with a README, or serve resource_documentation in the OAuth protected-resource metadata.

  • License10 pts

    Declare a license in the repository or the registry entry.
