Overview

AI-generated overview

A remote MCP endpoint offering small utility tools (time, URL and hostname parsing, HTTP status checks, simple validation) that mostly discard their input.

What you can do
Time and calendar: current UTC time, time in an IANA zone, and a list of common zone names. URL and hostname handling: normalize a URL, split a hostname into labels, parse GitHub and Figma URLs, check Jira key shape. Network checks: HTTP status and content type for public URLs, HEAD status, robots.txt group counts, Wikipedia title existence, Hacker News front-page count. Validation and counting: JSON validity, character counts, key counts, path and URL safety checks, simple arithmetic. Weather and place lookups via Open-Meteo, plus a fixed three-step thinking template. Several index tools that point to external pay-per-call, people-search and advertising gateways.
When to use it
Useful when an assistant needs quick, stateless helpers such as a timestamp, a URL or hostname breakdown, an HTTP status check, or a small format validation, without installing anything locally. Not suited to tasks needing the actual content of pages, files or data, since most tools discard their input.
Requirements
A remote streamable HTTP endpoint; no package, environment variable or header is declared, and no authentication is declared. Some tools make outbound requests to public URLs and to Open-Meteo, so network access is needed.
Before you install
The index tools (agent-tool-index, people-search-index, agent-ads-index) route to third-party gateways and instruct following redirect hops carrying tracking parameters; the ads one mentions a 7-day trial handoff to an operator, so expect commercial follow-ups. Several tools fetch arbitrary public URLs. Most tools discard input, so results are shallow rather than full data retrieval.

Installation

In SourceWeft

  1. Open Lowercase hex charset, input discarded 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.sadri-dridi%2Fhex-lcase/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

README

Named MCP utilities

Independently listed public MCP servers for autonomous clients. Each folder is one official registry name with its own converting intake.

Agent Ads doors

Doors that route autonomous agents to Agent Ads: labeled placement where agents look for tools, measured with daily HMAC nicknames, 7-day trial. Readiness doors also run a bounded website check.
