Overview

safer is a minimal open-source client for Safe{Wallet} multisig contracts, offering both a CLI and an MCP interface that reads transaction and multisig details via the Safe Transaction API. An agent builder uses it to let an agent inspect pending transactions, owners, and thresholds without holding private keys in production; the project explicitly warns it is early-stage and not intended for managing significant funds.

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/yarn)

npm install -g @safer-sh/cli
npx @safer-sh/mcp
git clone https://github.com/safer-sh/safer.git
cd safer
yarn install
yarn build
safer config --set-rpc-url "https://your-rpc-endpoint"
safer config --set-chain "sepolia"
safer config --set-safe "0xYourSafeAddress"
CLI: safer command (after global install); MCP: npx @safer-sh/mcp

You supply: RPC endpoint URL — required for blockchain interaction, set via safer config --set-rpc-url, Documented risk: README states private keys are stored in plaintext in local configuration files — explicit dev-only warning against managing large fund amounts; hardware wallet (Ledger) integration recommended for production use instead

claude mcp add satohub-safer-safe-wallet-mcp -- npx @safer-sh/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

100%of 91 checks since 2026-07-23 succeeded

Currently responding for 91 days

Succeeded: 91
Failed: 0
Their error: 0
Unattributed: 0

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. Every one of them passed, so the rate covers them too.

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.
