MCP-Scan

90/100open sourceexplicit relation

MCP-Scan is a security tool that scans MCP servers for vulnerabilities including tool poisoning, prompt injection, cross-origin escalation, and rug pull attacks. Acquired by Snyk in 2026, it is the first dedicated security scanner for the MCP ecosystem. It analyzes tool descriptions, permissions, and behavior patterns to detect malicious or compromised MCP servers before they can exploit AI agents.

100% free and open-source Model Context Protocol (MCP) security auditing and vulnerability scanner developed by Invariant Labs (Apache-2.0 License). Analyzes MCP client configurations, tool schemas, and server definitions to detect prompt injection vectors, malicious tool poisoning, cross-server shadowing, and unintended permission escalation at zero software cost.Review →

MEDUSA

open sourceexplicit relation

MEDUSA is an AGPL-3.0 AI-first security scanner from Pantheon Security that checks AI and machine-learning applications, LLM agents, MCP workflows, RAG pipelines, repository-poisoning risks, secrets, and agent-specific compromise patterns.

Medusa is 100% free and open-source under the GNU Affero General Public License v3.0 (AGPL-3.0). All core detection capabilities—including scanning for prompt injections, malicious MCP servers, and secrets leaks—can be run locally or integrated into CI/CD pipelines without licensing fees.
