Run

TerminalAgent

Through ot mcp, an agent calls run_tool with this; ot asks you before anything that goes online or touches a target. Set it up: ot mcp install claude (or cursor, vscode, codex, gemini).

{"tool":"osintverse-community/user-scanner"}

Or just say: "Run osintverse-community/user-scanner on … with OTInstaller." The registry's read-only MCP server at api.otinstaller.com/mcp can find tools without installing anything.

ot install osintverse-community/user-scanner

Python wheel, run in a read-only container (Docker optional with --native) · network allowed · no key · up to 20 min. The first ot run installs the tool after asking once. Drop --format table for JSON.

user-scanner (community package)

This repository packages github.com/kaifcodec/user-scanner for the OTInstaller Registry as osintverse-community/user-scanner. The tool is the work of its authors, under the MIT license; this repository only holds the manifest and release workflow.

Report problems with the tool upstream, and problems with the packaging here. If you maintain the upstream project and want to publish it yourself, open an issue or run ot claim osintverse-community/user-scanner: the package is transferred to you.

It installs the upstream project's own release from PyPI, pinned by version and hash; nothing here is rebuilt.

Give either a username or an email, not both. Results are printed as coloured text; the JSON export only writes to a file, so it is not used. The tool checks PyPI for a newer version at start-up and asks whether to update; with no terminal attached the question is skipped and the scan continues.
