Anlyon alternative

Run the operations that matter as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

Tools

Grouped by what each tool does, most consequential first. Open one for its reasons and full description; descriptions are the publisher's own words.

    Description, as the server wrote it
    NOAA forecast for an agricultural region — the next several day/night periods with temperature, wind speed and direction, and short and detailed forecast text, from the National Weather Service. Use for the outlook ahead; use get_weather instead for current observed conditions, and get_weather_history for recent past weather. Live proxy to NOAA — nothing is stored; this is the latest NWS gridpoint forecast for the region's coordinates; no API key. An unknown location key or a NOAA outage returns a source-unavailable error.

    Description, as the server wrote it
    Current observed weather conditions for an agricultural region — temperature, humidity, wind, and sky conditions from the nearest NOAA National Weather Service station. Use for right-now conditions; use get_forecast instead for the outlook ahead, and get_weather_history for what the past days actually delivered. Live proxy to NOAA — nothing is stored, so values are as of the station's latest observation; no API key. An unknown location key or a NOAA outage returns a source-unavailable error.

    What it can reach

    • untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
    Description, as the server wrote it
    Recent past weather for an agricultural region, summarized by day from NOAA station observations: daily high and low temperature (°F), total precipitation (inches), and the number of observations behind each day. Use for what weather actually occurred over the past days; use get_weather instead for current conditions and get_forecast for the outlook. Live proxy to NOAA — nothing is stored; no API key. `days` spans 1–30 (default 7). Precipitation is null for a day when the station reported no precipitation values — never silently zero — and days with no observations are omitted.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged private-data or outbound.

Reads private data0
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write3
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out0
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Remote posture

Findings

Matches of fixed checks, with the text they matched.

No check matched anything in these tool definitions. That is not a safety guarantee.

History

Changes to its tool definitions and to its remote endpoint, newest first.

No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.

All changes to this server

Install

Pinned to version 1.0.1. Values in angle brackets are yours to fill in.

claude mcp add --transport http weather https://weather.morningbrief.link/mcp
claude mcp add --transport http weather https://weather.morningbrief.link/mcp

Run in a terminal.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__weather__get_weather",
      "mcp__weather__get_forecast",
      "mcp__weather__get_weather_history"
    ],
    "ask": [],
    "deny": []
  }
}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as weather. Review it before you use it.

Capability tags behind 3 rules

Pin

Keep the decision: fail CI when the tools change, follow every change, or show a badge.

Pin in CI

Fail a build when the tools you reviewed are not the tools the server serves today.
