cut-cdn

v0.0.0-git.2105f01Verified publisher

Filters out IP addresses that belong to known CDN providers, leaving the ones that point at real origin servers

Community-packaged from github.com/ImAyrix/cut-cdn: the registry's community pins the upstream release; the tool is its authors' work. Maintain that project? Claim this package.

Run

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/cut-cdn","target":"1.1.1.1","input_type":"ip"}

Or just say: "Run osintverse-community/cut-cdn on 1.1.1.1 with OTInstaller." The registry's read-only MCP server at api.otinstaller.com/mcp can find tools without installing anything.

ot run osintverse-community/cut-cdn ip:1.1.1.1 --format table
ot install osintverse-community/cut-cdn

Docker image in a read-only container · network allowed · no key · up to 5 min. The first ot run installs the tool after asking once. The example value is the registry's own test input, so this command has run. Drop --format table for JSON.

cut-cdn (community package)

This repository packages github.com/ImAyrix/cut-cdn for the OTInstaller Registry as osintverse-community/cut-cdn. 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/cut-cdn: the package is transferred to you.

The Dockerfile here builds the upstream release at a pinned version, and the otinstaller release workflow builds, signs and publishes the image.

Pinned to a commit after the v1.0.31 release that stops a crash when the update check cannot read the latest version. The build bumps github.com/modern-go/reflect2 to v1.0.2, which current Go needs. An address that is in a CDN range prints nothing, so an empty result means the target is behind a CDN.
