rain-collateral-admin

What this skill does

Retrieves the wallet address(es) attached to a Rain user's collateral contract by querying the Weather Station internal API. Returns the EVM wallet (collateral contract admin), plus Solana/Stellar/Tron addresses if set.

Requirements

• Claude in Chrome tools must be available (tabs_context_mcp, navigate, javascript_tool)
• Weather Station is only accessible on VPN — if you get a connection error, let the user know they need to be on VPN

Steps

Step 1 — Get a browser tab

Use tabs_context_mcp (with createIfEmpty: true) to get an available tab ID.

Step 2 — Navigate to Weather Station

Navigate the tab to https://weatherstation.rain.xyz. This loads the page and ensures the auth session is active. Wait for the navigation to complete.

Step 3 — Fetch user data using the session auth

Run this JavaScript in the tab, substituting the actual user ID:

(async () => {
  const token = localStorage.getItem('authToken');
  if (!token) return JSON.stringify({ error: 'No authToken found — are you logged in to Weather Station?' });
  const resp = await fetch(`https://weatherstation-api.rain.xyz/api/users/USER_ID_HERE`, {
    headers: { 'Authorization': `Bearer ${token}` }
  });
  const data = await resp.json();
  if (!data.user) return JSON.stringify({ error: data.message || 'User not found', status: resp.status });
  const u = data.user;
  return JSON.stringify({
    evmAddress: u.address,
    solanaAddress: u.solanaAddress,
    stellarAddress: u.stellarAddress,
    tronAddress: u.tronAddress,
    userId: u.id,
    name: `${u.firstName} ${u.lastName}`,
    email: u.email,
  });
})()

Step 4 — Return the result

Parse the JSON returned by the script and present it clearly:

• EVM wallet address (collateral contract admin): the evmAddress field — this is the primary address, the one set as admin on the user's Rain smart contract
• Solana address: solanaAddress (if set)
• Stellar / Tron: surface these too if non-null

If evmAddress is null, note that this user may not have an EVM wallet set.

Error handling

Situation	What to do
No authToken found	Ask the user to open Weather Station in Chrome and log in, then retry
401 Unauthorized	The session may have expired — ask the user to log in to Weather Station again
404 / User not found	Confirm the user ID is correct; double-check it's a production (not sandbox) ID
Connection refused / timeout	Likely not on VPN — ask the user to connect to VPN and retry

Example output

For user e6a8122e-69b8-40c6-8d89-f940517b66db:
