Tools & Capabilities Breakdown

Osv Ui Tools (4)

scan_project

Scan a project directory for CVE vulnerabilities. Automatically detects npm, Python, Go, Rust, Java/Maven, PHP/Composer, and Ruby/Bundler manifests. Queries live CVE data from OSV.dev. Returns structured vulnerability report with severity counts, risk score, and fix recommendations. Use this as the first step before open_dashboard or apply_fixes.

open_dashboard

Launch the osv-ui visual dashboard in the browser for human review. This is the HUMAN-IN-THE-LOOP step — always offer this before applying fixes. The dashboard shows full CVE details, severity charts, and the upgrade guide. Returns the dashboard URL. If already running for this path, returns existing URL.

get_fix_commands

Get the safe upgrade commands for vulnerable packages WITHOUT executing them. Use this to show the user what will be changed before calling apply_fixes. Returns a list of commands grouped by ecosystem (npm, pip, go, cargo, Maven, Composer, Bundler).

apply_fixes

Execute package upgrade commands to fix CVEs. IMPORTANT: This is a DESTRUCTIVE action that modifies package files. ALWAYS call get_fix_commands first and confirm with the user before calling this. Returns the command output for each fix applied.
