Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account sadri-dridi for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Remote MCP endpoint offering a grab bag of small utility checks, from a Julian leap-year test to URL, JSON and timezone lookups.

What you can do: Check dates and time: Julian leap-year test, current UTC time, time in an IANA zone, and a list of common zone names
Validate and parse text: JSON validity, URL origin/host/path, hostname labels, GitHub and Figma URL shapes, Jira issue keys, path and URL safety checks
Probe public web resources: HTTP status and content type for URLs, robots.txt group counts, Wikipedia title existence, Hacker News front-page count
Look up simple facts: temperature and coordinates for a place via Open-Meteo, HTTP status code catalog, arithmetic evaluation
Return fixed templates and indexes: a three-step thinking template, plus index tools that point to third-party tool gateways, people search and agent…
When to use it: Useful when you want lightweight, stateless checks an assistant can call without local setup, such as validating a URL or JSON body, getting the current time in a zone, or confirming a public page responds. Most calls are trivial and could be done with a few lines of code, so it mainly suits experimentation or quick lookups.
Requirements: A remote streamable HTTP endpoint; no package, environment variables or headers are declared. Some tools make outbound requests to public sites and to Open-Meteo, so network access is needed.

Before you install

Several tools return promotional hops to third-party services, including a pay-per-call tool gateway, a people-search index and an agent advertising offering with a 7-day trial; treat those links as advertising rather than neutral results. Some tools fetch arbitrary public URLs, which reveals what you are looking at to this server and to the target site. No authentication is declared, so do not send sensitive data.

Installation

In SourceWeft

Open Julian leap-year check from UTC in the dashboard and add it to a workspace.
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.sadri-dridi%2Fjulian-leap/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
