Check Solana wallets from your AI app

SealGuard's MCP server lets Claude, Cursor, VS Code and other AI apps run the same wallet check as this site. Ask "is this wallet safe?", "which approvals are still open?" or "how much SOL can I get back from empty accounts?" and get an answer from the chain.

Server URL: https://guard.2cstudio.app/mcp

Free, no sign-in and no API key. It's read-only: it never asks for a seed phrase and can't send a transaction. When something needs fixing, the answer includes a link to SealGuard, where the wallet's owner connects their wallet and approves each fix.

Add it to your AI app

Claude (claude.ai and the desktop app): Settings → Connectors → Add custom connector, then paste the server URL.

Claude Code:

claude mcp add --transport http sealguard https://guard.2cstudio.app/mcp

Cursor (~/.cursor/mcp.json):

{ "mcpServers": { "sealguard": { "url": "https://guard.2cstudio.app/mcp" } } }

VS Code (.vscode/mcp.json):

{ "servers": { "sealguard": { "type": "http", "url": "https://guard.2cstudio.app/mcp" } } }

Any other client that supports remote MCP servers over Streamable HTTP works the same way.

Tools

scan_wallet: a 0–100 safety score and everything found: open token approvals, phishing airdrops, Token-2022 permanent delegates and transfer restrictions, stake and nonce accounts someone else controls, and whether the wallet account itself has been taken over. Also totals the SOL in empty token accounts.
list_empty_token_accounts: each empty token account, the SOL rent in it, and which ones SealGuard suggests closing. Accounts for tokens you'll likely receive again, or used in the last 30 days, are marked to keep, with the reason.
list_token_approvals: every address that can still move tokens out of the wallet, and how much, plus permanent delegates that holders can't revoke.

Things to ask

"Is wallet <address> safe? Explain anything risky in plain words."
"How much SOL can I get back from empty token accounts in <address>?"
"Does <address> have any token approvals I should revoke?"

Limits and privacy

Each check reads the wallet from the Solana network, so there are limits: 30 checks an hour from one connection, and a daily total across everyone. SealGuard doesn't store the addresses you check. It keeps a count of calls per connection, under a one-way hash, for up to two days, for the limit. Results are general information, not financial or security advice: see the terms.

Fixing what it finds

Revoking approvals and burning phishing tokens are free. Closing empty token accounts costs 5% of the SOL returned, paid in the same transaction, and nothing for wallets with the guard. For the step-by-step guides, see closing empty token accounts and revoking token approvals.
