Presign Guard Wallet MCP
fritsie13 · MCP server
Your AI agent gets its own wallet, funded by you, to pay x402 and MPP APIs and send USDC, within limits you set, such as a cap per payment and a daily budget. Payments above a limit wait for your approval on Telegram or a wallet server dashboard, and each signature is checked by presign-guard against known drainers, sanctioned addresses and look-alike tokens, except on Tempo. Each check has a fee, paid from the same wallet or from prepaid credits. Limits and approvals can run through a hosted wallet service you sign in to or a wallet server of your own.

Why it's useful
Your agent can pay for APIs on its own without an open-ended budget: it works within your limits and asks you before anything above them.
What you could do with it
- Ask your agent to find a paid weather API in the x402 catalogue and pay for one forecast within your limits.
- Set a cap per payment and a daily budget, then approve or deny larger payments from Telegram.
- Ask your agent for its wallet status to see its address, balances, limits and what is left today.

Maintenance
Not measuredNo release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.
Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured

In its maker's words
An MCP server that gives AI agents (Claude, Cursor, …) a wallet with spending limits: pay x402 and MPP APIs (USDC on Base, USDC.e on Tempo incl. sessions, RLUSD on the XRP Ledger, USDC on Algorand) and send USDC, every payment checked by presign-guard or

- What it establishes
- Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
- What it does not
- How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
- Exactly what was read
- Version 0.13.2, the file with digest sha512-hbQN+YYZqV6I5Nn05EVnGnSPqzrhrdw2IrLLbftzBawP7+RHOFBX1kvll9a0yt7zSV18kbQ2vHMmho6Mi0txiw==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
- Authentication
- Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.
