Add the Temporal MCP server to Claude Code

Config last verified Jun 1, 2026

The exact config to run Temporal in Claude Code — paste it in, restart, and the tools load.

Prerequisites

Claude Code installed.

Setup

1. Open `~/.claude.json`

2. Add this configuration

Add to ~/.claude.json

~/.claude.json

json

{
  "mcpServers": {
    "temporal": {
      "command": "uvx",
      "args": [
        "temporal-mcp-server",
        "--host",
        "localhost:7233",
        "--namespace",
        "default"
      ],
      "env": {
        "TEMPORAL_HOST": "<TEMPORAL_HOST>",
        "TEMPORAL_NAMESPACE": "<TEMPORAL_NAMESPACE>",
        "TEMPORAL_API_KEY": "<TEMPORAL_API_KEY>"
      }
    }
  }
}

Or via CLI

bash

claude mcp add temporal -- uvx temporal-mcp-server --host localhost:7233 --namespace default

3. Restart Claude Code and confirm the Temporal tools load.

Gotchas

Claude Code stores MCP servers under an "mcpServers" object in ~/.claude.json. It also reads a project-scoped .mcp.json and supports adding servers from the command line with "claude mcp add". Each entry must declare either a "type" or a "command"; Claude Code refuses an entry that has neither. Remote servers connect natively over Streamable HTTP with OAuth.
