PlainText Wallet Approval Checker is an MCP server with 3 tools an agent can call, among them check_wallet_approvals, explain_approval, feedback. It answers at https://plaintext.fizzl.eu/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 3 of 4 times since 23 September 2026; the last check, on 7 November 2026, succeeded.
Explains wallet approvals and signature requests in plain language: SAFE, CAUTION or RISK.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
check_wallet_approvals | Check an EVM wallet's live token/NFT approvals and get a plain-language safety verdict (SAFE, CAUTION, or RISK) with an explanation. The verdict comes from presign-guard's approval audit (who each spender is, which to revoke). Inputs: address, chain, kind |
explain_approval | Explain an arbitrary approval/permission JSON payload in plain language, when you already have the data instead of needing an on-chain lookup. Inputs: data |
feedback | Report a bug, a missing feature or anything else about this service, in a structured way. Free. A person reads every report; nothing is run or changed automatically. Inputs: type, message, endpoint, contact |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://plaintext.fizzl.eu/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: io.github.fizzl13. Endpoint host: plaintext.fizzl.eu. ARD identifier: urn:air:io.github.fizzl13:mcp:plaintext-wallet-checker.
