io.github.MikehzpPublished by GitHub account Mikehzpv0.4.2Updated Oct 24, 2026
Scan AI agents for tool-calling vulnerabilities: prompt leaks, hijacking, injections, and more.
Overview
Scans AI agents for tool-calling vulnerabilities such as prompt leaks, hijacking, and injections.
- What you can do
- Agent Security Scanner is a local MCP server that lets an assistant run security scans against AI agents, focusing on tool-calling weaknesses. According to its description, it checks for prompt leaks, hijacking, injections, and similar issues. No individual tools are listed in the manifest, so the exact commands and outputs are not documented here.
- When to use it
- Consider it when you are building or testing an AI agent that calls tools and want a quick way to probe for prompt leakage, hijacking, or injection weaknesses. It is aimed at security review of agent behavior rather than general application scanning.
- Requirements
- Runs as a local process on the user's machine, installed from the PyPI package agentvuln over stdio. It is desktop only and has no web executable. No authentication, environment variables, or headers are declared, so no credentials appear to be needed.
Installation
In SourceWeft
- Open Agent Security Scanner in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Score
25% of the applicable checks met
How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
- Reached in the last 30 days25 pts
Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.
- Auth declared10 pts
Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
- Tools listed15 pts
Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
