Overview

Purple Flea Wallet is an MCP server and REST API that generates BIP-39 HD wallets for an AI agent across multiple chains (Ethereum, Base, Solana, Bitcoin, Tron, Monero, and others) from one mnemonic, and exposes balance checks, sending, and cross-chain swaps routed through the Wagyu aggregator. An agent builder uses it to give an agent a self-custodied wallet and swap execution without a third-party custodian.

Self-reported rows are the project’s own words, dated when we recorded them — not a check. Only reproduced and reviewed rows carry a mark. None of these rows is a safety or quality rating.

Install — reproduced in a container Sep 14, 2026

Runtime: Node.js (npm/npx package)

{"mcpServers": {"purple-flea-wallet": {"command": "npx", "args": ["-y", "@purpleflea/wallet-mcp"], "env": {"WALLET_API_URL": "https://wallet.purpleflea.com"}}}}

You supply: WALLET_API_URL — optional, defaults to https://wallet.purpleflea.com, No local private-key env var documented in the README; the connected wallet API states mnemonics/private keys are agent-managed and never stored server-side — vendor claim, not independently verified

Add to Cursor Add to VS Code

claude mcp add satohub-purple-flea-wallet -- npx -y @purpleflea/wallet-mcp

A local server: your client runs this command on your machine. Installing runs third-party software under your own credentials. Sato Hub publishes the documented invocation and, where the harness reproduced it, the date it did — neither is a safety review.

Observed record — 91 daily checks since 2026-07-23

0%of 51 checks since 2026-09-01 succeeded

Currently unreachable from our probe for 51 days

Succeeded: 30
Failed: 61
Their error: 0
Unattributed: 61

State changed on 2026-08-22 (responding → unclear), 2026-09-01 (unclear → unreachable from our probe).

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 40 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. The rate above leaves those checks out; the counts include them.

A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.
