How to install Time in Claude CodeAnthropic's agentic CLI

  1. Add the server

    bash
    claude mcp add time -- uvx mcp-server-time
  2. Verify it's connected

    bash
    claude mcp list
  3. Sharing it with your team?

    Add `--scope project` to write it to .mcp.json in the repository root, which you can commit (with the secrets left as environment variables).

  4. Use it in a session

    Ask Claude to use the tools this server exposes (e.g. get_current_time, convert_time). It discovers them automatically.

What the code can do

Source analysis currently covers npm packages only. This server ships as a Python package, which needs a different parser.

What it can reach

  • Runs code on your machine — Executes as a local process with your user's permissions, including filesystem access.
  • Downloads at launch — The package is fetched from its registry each run unless you pin a version.
  • Last commit today — Actively maintained.
  • 92k GitHub stars — Community adoption signal.

Documentation

Full README

Time MCP Server

A Model Context Protocol server that provides time and timezone conversion capabilities. This server enables LLMs to get current time information and perform timezone conversions using IANA timezone names, with automatic system timezone detection.

Source: https://github.com/modelcontextprotocol/servers/tree/main/src/time

Requires MCP Python SDK 2.x (mcp>=2.3,<3).

Available Tools

  • get_current_time - Get current time in a specific timezone or system timezone.
  • Required arguments:
  • timezone (string): IANA timezone name (e.g., 'America/New_York', 'Europe/London')
  • convert_time - Convert time between timezones.
  • Required arguments:
  • source_timezone (string): Source IANA timezone name
  • time (string): Time in 24-hour format (HH:MM)
  • target_timezone (string): Target IANA timezone name

A timezone name, here and in --local-timezone, must be an exact IANA key, case included: Europe/Warsaw is accepted and europe/warsaw is rejected on every platform, including macOS, whose case-insensitive filesystem would otherwise resolve it.

Protocol versions

The server speaks both eras of the Model Context Protocol over stdio, with nothing to configure: a 2026-07-28 client (discovered with server/discover, no session) and a 2025-11-25 client (the initialize handshake). The client's first request decides which. Tools behave the same in both. Methods the 2026-07-28 specification removes, such as ping, are answered only on a 2025-11-25 connection.

Results and errors

The server is built on the SDK's high-level MCPServer. Each tool declares an outputSchema and returns its result twice: as structuredContent, and as the same object in indented JSON in a text block, for a client that does not read structured output.

  • A tool failure is an `isError` result whose text the model can read and act on, prefixed Error executing tool <name>: . That covers an unknown or non-exact timezone (Invalid timezone: ...), an empty timezone (Missing required argument: <argument>), a time not in HH:MM 24-hour form, a wall-clock time skipped by a clock change, and an argument missing or of the wrong type (the SDK's validation message).
  • An unknown tool name is a JSON-RPC `-32602` error (Unknown tool: <name>), not an isError result, as both protocol versions specify.
  • The server registers no prompts or resources. Their list methods answer with empty lists.
