Local keystore + MCP server. Claude can sign EVM transactions but never sees the private key.

Claude can sign, but never see. is a local signing tool and Claude Code integration that lets agentic coding tools use private keys without ever putting key material in the model's context window. Status: pre-alpha. The MCP server, CLI, unlock flow, ward hooks, and policy engine (static checks) all work end-to-end. Out-of-band confirmation, rolling-window value caps, and EIP-712 domain allowlists…

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.

Verification confirms publisher identity (repo ownership), not code safety. The security scan covers known CVEs and suspicious install scripts.

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.

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.
