Overview

AI-generated overview

A free hosted developer toolkit that gives an assistant quick utilities for time, UUIDs, hashing, Base64, JWT decoding, JSON and CSV conversion.

What you can do
Get the current time and convert timestamps into relative deltas or readable form, and generate random UUIDv4s in batches of 1 to 100. Compute SHA-256, SHA-1, SHA-512 and MD5 hex digests of text. Encode text to Base64 and decode Base64 back to UTF-8 text, with errors on invalid input. Decode a JWT header and payload and report its expiry status. Validate JSON with line and column on errors, pretty-print it with 2-space indent, or minify it. Convert CSV with a header row into an array of row objects.
When to use it
Handy when you need small, one-off developer conversions during a conversation: checking a timestamp, generating IDs, hashing or Base64-encoding a string, inspecting a JWT payload, cleaning up JSON, or turning a CSV snippet into JSON. It saves writing throwaway scripts for these tasks.
Requirements
A remote streamable HTTP endpoint; no local runtime, package, account, API key or environment variable is declared. Network access to the hosted endpoint is required.
Before you install
The JWT tool only decodes and does not verify signatures, so decoded claims should not be trusted as authentic. Anything you send, including tokens, hashes and text, goes to a third-party hosted service, so avoid pasting secrets or sensitive production data.

Installation

In SourceWeft

  1. Open devutils 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/net.bigfloppy.devutils%2Fdevutils/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

Other MCP clients

Add this to your client's mcpServers config.
