Install OpenWeatherMap

— pick your client, copy, paste.
claude_desktop_config.json
{
  "mcpServers": {
    "openweather": {
      "command": "npx",
      "args": [
        "-y",
        "weather-mcp-server"
      ],
      "env": {
        "OPENWEATHER_API_KEY": "${OPENWEATHER_API_KEY}"
      }
    }
  }
}

Paste under mcpServers. Fully quit and reopen Claude after editing.

CLI or .mcp.json
# export OPENWEATHER_API_KEY=your_openweather_key
claude mcp add openweather -- npx -y weather-mcp-server

Run from your repo. Commit .mcp.json to share with your team.

.cursor/mcp.json
{
  "mcpServers": {
    "openweather": {
      "command": "npx",
      "args": [
        "-y",
        "weather-mcp-server"
      ],
      "env": {
        "OPENWEATHER_API_KEY": "${OPENWEATHER_API_KEY}"
      }
    }
  }
}

Global path: ~/.cursor/mcp.json. Reload window after editing.

.vscode/mcp.json
{
  "servers": {
    "openweather": {
      "command": "npx",
      "args": [
        "-y",
        "weather-mcp-server"
      ],
      "env": {
        "OPENWEATHER_API_KEY": "${OPENWEATHER_API_KEY}"
      }
    }
  }
}

VS Code uses the "servers" key (not "mcpServers").

~/.codeium/windsurf/mcp_config.json
{
  "mcpServers": {
    "openweather": {
      "command": "npx",
      "args": [
        "-y",
        "weather-mcp-server"
      ],
      "env": {
        "OPENWEATHER_API_KEY": "${OPENWEATHER_API_KEY}"
      }
    }
  }
}

Open via Cascade → hammer icon → Configure.

cline_mcp_settings.json
{
  "mcpServers": {
    "openweather": {
      "command": "npx",
      "args": [
        "-y",
        "weather-mcp-server"
      ],
      "env": {
        "OPENWEATHER_API_KEY": "${OPENWEATHER_API_KEY}"
      }
    }
  }
}

Open via the Cline sidebar → MCP Servers → Edit.

~/.continue/config.json
{
  "experimental": {
    "modelContextProtocolServers": [
      {
        "transport": {
          "type": "stdio",
          "command": "npx",
          "args": [
            "-y",
            "weather-mcp-server"
          ],
          "env": {
            "OPENWEATHER_API_KEY": "${OPENWEATHER_API_KEY}"
          }
        }
      }
    ]
  }
}

Continue uses modelContextProtocolServers with a transport block.

~/.codex/config.toml
# ~/.codex/config.toml
[mcp_servers.openweather]
command = "npx"
args = [
  "-y",
  "weather-mcp-server",
]
env = { OPENWEATHER_API_KEY = "${OPENWEATHER_API_KEY}" }

Codex uses TOML. Each server is a [mcp_servers.<name>] subtable.

~/.config/zed/settings.json
{
  "context_servers": {
    "openweather": {
      "command": {
        "path": "npx",
        "args": [
          "-y",
          "weather-mcp-server"
        ]
      },
      "env": {
        "OPENWEATHER_API_KEY": "${OPENWEATHER_API_KEY}"
      }
    }
  }
}

Zed calls them "context_servers". Settings live-reload on save.

ChatGPT → Settings → Connectors → Developer mode
{
  "name": "OpenWeatherMap",
  "transport": "stdio",
  "command": "npx",
  "args": [
    "-y",
    "weather-mcp-server"
  ],
  "env": {
    "OPENWEATHER_API_KEY": "${OPENWEATHER_API_KEY}"
  }
}

Enable Developer mode (paid plans) and enter these values in the UI.

Quick answer

What it does

Wraps OpenWeatherMap's current, forecast, and one-call APIs as MCP tools. Input: lat/lon or city; output: structured conditions and forecasts.

Best for

  • Trip planning assistants
  • Logistics weather checks
  • Event-day briefings
  • Lifestyle + outdoor flows

Not for

  • Aviation or marine forecasting
  • Hyper-local severe-weather alerting

Setup recipe

  1. 1

    Install

    Copy the install snippet for your client from the Install section above.

  2. 2

    Set required secrets

    Set OPENWEATHER_API_KEY in your shell environment before launching your MCP client.

  3. 3

    Try a minimum working prompt

    Plan a week around the weather

    What will the weather be in Tel Aviv for each of the next 7 days? Return: day, high/low, rain probability, and a 1-sentence summary. Flag any day with >60% rain probability.

    Tested with: Claude Desktop, Cursor.

Tools & permissions

Tools list pending verification. The server exposes tools over MCP; we haven’t yet parsed its capability manifest into this page. Check the GitHub repo for the authoritative list.

Security & scope

Access scope
Network
Sandbox
Read-only calls to the OpenWeatherMap API using the key in env.
Gotchas
  • The free tier returns cached data up to ~10 minutes old; do not use it for safety-critical nowcasting.

Agent prompt pack

— copy into Claude, Cursor, or ChatGPT.
Paste into Claude, Cursor, or ChatGPT. Edit the [brackets] before sending.
Recommend the best MCP servers for [task: e.g. maps, location & weather work] in [client: Claude].

Constraints:
- Prefer tools that are [official | open-source | read-only] — pick what matters for my use case.
- Exclude MCPs that require [e.g. a paid plan, OAuth-only flows, remote-only transport].
- Return at most 3 picks, ranked.

For each pick include:
1. One-sentence rationale.
2. The ready-to-paste install snippet for my client.
3. Any required secrets I need to create before installing.

Cross-check the top-mcps.com listing: https://top-mcps.com/top-mcps-for-maps-location-weather
Compare OpenWeatherMap against a real alternative. Swap the second MCP in [brackets] if you want a different match.
Compare OpenWeatherMap MCP vs [Google Maps MCP] for the following job: [describe the job, e.g. "let an agent create GitHub issues on bug triage"].

Judge them on:
- Setup time and complexity (what a new user hits first).
- Auth model (none / API key / OAuth 2.1) and credential risk.
- Transport (stdio / Streamable HTTP / SSE) and where the server runs.
- Required secrets and the blast radius if they leak.
- Operational risk in an unattended agent loop.
- Which one is "good enough" for a weekend prototype vs. production.

End with one sentence: which should I pick for my scenario, which is: [my scenario].

Asks the agent to install and verify. Works inside Claude Code, Cursor Agent, Codex CLI.
Install the OpenWeatherMap MCP server for my [client: Claude] at the default config path for that client.

Use the exact install snippet published at https://top-mcps.com/mcp/openweather (fetch https://top-mcps.com/mcp/openweather.json for the canonical server.json if you can read URLs).

Before finishing:
1. Create the required secrets (OPENWEATHER_API_KEY) and put them in the appropriate env block — do not hard-code them.
2. Restart or reload the client so it picks up the new server.
3. Verify the server is connected (green / running state) and at least one tool is listed.
4. If anything fails, read the client's MCP logs and report the exact error — do not silently retry.

Confirm when done and list the tools the server now exposes.
