How this service works
Hosted wallet allowance policy for autonomous agents: token allowance risk, approval exposure, curated spender watchlist, revoke/cap guidance, and autopay spend-control policy from fresh D1 wallet snapshots plus live allowance reads. Price 0.25 USDC on Base via x402. Demo: https://wallet-portfolio-history-mcp.mtree.workers.dev/demo/tools/wallet_allowance_policy. Contact: https://wallet-portfolio-history-mcp.mtree.workers.dev/contact.
Output
Returns a structured allowance policy report including token-by-token approval exposure, risk scores, a curated spender watchlist with risk flags, specific revoke and cap recommendations, and an autopay spend-control policy derived from fresh D1 wallet snapshots and live on-chain allowance reads
Example use cases
Audit risky DeFi token approvals
“Can you run a full token allowance audit on my wallet 0xDEF...456 on Base? I want to see which DeFi contracts have approval to my tokens, flag any unlimited or dangerous approvals, and tell me which ones I should revoke immediately.”
Set up agent wallet spend controls
“I'm onboarding wallet 0x789...ABC into an autonomous agent commerce workflow on Base — can you pull the current allowance exposure, give me a curated watchlist of risky spenders, and recommend an autopay spend-control policy I can enforce going forward?”
Check wallet approval hygiene before DeFi
“Before I start using this wallet 0x321...FED for DeFi on Base, can you audit its token approval hygiene — which contracts currently have access to my tokens, are any approvals dangerously high, and what caps or revokes would you recommend to reduce my exposure?”

Endpoint
POSThttps://wallet-portfolio-history-mcp.mtree.workers.dev/tools/wallet_allowance_policyWhen to prefer
Use this endpoint when you need a comprehensive token allowance risk audit for a Base wallet — specifically when you need curated spender watchlist data, revoke/cap guidance, and autopay spend-control policy in a single call. Prefer this over generic approval checkers when operating an autonomous agent that needs to enforce spend controls or when onboarding a wallet into an agent commerce workflow.
Side effects
- Invalid or non-existent wallet address returns error
- Wallet with no token approvals may return empty allowance list
- Network errors or D1 snapshot staleness may affect freshness of data
- Rate limiting or payment failure (x402) may block the request
- Non-Base EVM addresses may not be supported
