v0.19.0io.github.Fizzl13MITUpdated 6d agonpmGitHub

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 Solana and Algorand) and send USDC, every payment checked by presig

Inferred from the transports this listing declares (stdio). A client not listed here hasn’t been ruled out — it just isn’t something Forge can confirm.

Attested build
A verified provenance attestation binds this artifact to the listed repository. Nobody has claimed the listing yet — this proves where the code was built, not who stands behind it.

Tools

7 tools · none privileged
Statically extracted from the published packagev0.19.0 · 4d ago

Read out of the source npm actually ships, at scan time. The package was never executed. Tools registered dynamically at runtime, or hidden inside bundled or minified code, can be missed — so this is a floor on the tool surface, not a complete census of it.

wallet_statusThis agent's wallet: address, chain, balances, spending limits, what is left today, how approvals work, and whether it is paused. Check it before spending.

5 of 7 tools published a description.

Tool names and descriptions are written by the publisher and shown verbatim as inert text. They are the strings an MCP client passes to a model, so Forge scans them for prompt-injection patterns — any finding appears with the security scan above. “Privileged” is a keyword match on the tool name, not an audit of what the tool does: a benign-sounding name can still do anything.

Dependency tree

What one Forge scan resolved from npm metadata on 2026-10-21 — observed resolution, not a publisher declaration.

60 packages resolved · 13 direct · none carrying advisories Resolution stops at depth 4 and 60 packages.

The crawl stopped at the 60-package limit. The rest of the tree was never resolved.

36 more resolved packages are not drawn here (display cap: 24). Every dependency carrying an advisory is drawn regardless of the cap. Full inventory (CycloneDX SBOM)

Declared but not resolved

192 declared dependencies never landed in the tree. They are missing from Forge's resolution, not from the package.

+180 more not listed. The counts by reason above cover all of them.

Not followed: peerDependencies. This tree covers runtime dependencies only, so anything those pull in was never resolved.
