history
Project history and usage
Kingfisher is MongoDB's open source secret scanning and live validation tool, written in Rust for high-throughput scans of repositories, files, archives, cloud storage, collaboration systems, and CI workflows.
Project history
MongoDB presented Kingfisher publicly in June 2025 after describing it as a project that began as an internal effort to detect and verify exposed credentials. The project couples fast pattern matching with validation checks so security teams can distinguish inactive-looking findings from active credentials that require urgent rotation or revocation.
The repository history and release stream show a fast-moving post-release project. GitHub releases list Kingfisher v1.12.0, v1.13.0, and v1.14.0 on June 25-26, 2025, and v1.103.0 through v1.105.0 during June 16-29, 2026.
Adoption history
MongoDB's announcement framed Kingfisher as a core part of MongoDB's internal security workflows before its public release. Homebrew packaging made the CLI installable for macOS and Linux users through the same channel many security engineers use for scanners and developer tools.
How it is used
Kingfisher is used to scan source trees, Git history, platform integrations, archives, and storage targets for leaked API keys, tokens, and credentials. Its CLI can emit JSON, SARIF, TOON, and HTML reports, validate supported secrets against provider APIs, revoke selected secret types, and open a local or hosted report viewer.
Why package nerds care
For package collectors, Kingfisher sits in the modern secret-scanner lineage with Gitleaks, TruffleHog, and Nosey Parker, but its package identity is shaped by Rust, Hyperscan/Vectorscan-style performance work, validation, SARIF output, and a report viewer bundled with the CLI.

Recommended review
Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.
