Overview

AI-generated overview

A remote MCP server that gives an assistant current time by timezone, astronomy events, and moon phases.

What you can do
This server exposes tools for looking up the current time in a given timezone, along with astronomy events and moon phase information. It runs as a hosted remote endpoint, so the assistant connects to it directly rather than starting a local process. No tools are listed in the manifest, so the exact tool names and parameters are not documented here.
When to use it
Worth adding when an assistant needs reliable timezone-aware current time or simple astronomy and moon phase lookups, for example scheduling across regions or answering date and sky questions. It is not needed if you only require local system time.
Requirements
A remote MCP client that supports streamable HTTP, with network access to the provider's endpoint. No packages, environment variables, headers, or authentication are declared.
Before you install
The manifest declares no authentication, so requests may be unauthenticated and the provider can see the timezones and queries sent. No write, payment, or credential-handling behavior is indicated.

Installation

In SourceWeft

  1. Open Time & Astronomy 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/org.memoryapi%2Ftime/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.

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.
