Overview

AI-generated overview

A remote MCP endpoint offering 20 free developer utilities such as JSON/YAML, XML/SQL, Cron, SEO, QR code, URL shortening and file tools.

What you can do
This server exposes a set of free developer utilities through a remote MCP endpoint. The listed tools cover data format conversion and validation (JSON/YAML, XML/SQL), Cron expression handling and cron tasks, SEO helpers, QR code generation, URL shortening, and file-related operations. It is a general-purpose toolbox rather than a single-purpose integration.
When to use it
Worth adding when an assistant needs quick access to common developer utilities — converting or validating structured data, working with cron schedules, generating QR codes or short links, or basic SEO and file tasks — without installing local tooling.
Requirements
A remote MCP client that supports streamable HTTP, connecting to the provider's endpoint. No packages, environment variables, headers or authentication are declared, so no credentials appear to be needed.
Before you install
The manifest declares no authentication, so requests may be unauthenticated and any data sent to the endpoint leaves the user's machine. The tool list is not published, so the exact behavior of each utility, including whether any tool writes, sends or deletes data, cannot be verified from the available information.

Installation

In SourceWeft

  1. Open 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/site.jiebang.www%2Ftools/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
