MCP security is a critical gap. The attack surface is real and growing:
But no comprehensive scanner exists.
Traditional MCP security workflow:
check tool descriptions -> read JSON manually, hope you spot poisoning
review source for exec() -> grep -r "exec\|eval\|spawn" (misses 90% of sinks)
audit config files -> open each JSON, check by hand
check dependencies -> npm audit (misses typosquatting, install scripts)
compare tool definitions -> diff two JSON blobs by eye (rug pull detection)
OWASP compliance -> no tooling exists, read the PDF yourself
────────────────────────────────
Total: hours per server, mostly missing subtle issuesmcp-security-scanner gives your AI agent 55 tools across 6 categories. The agent connects to any MCP server (stdio, HTTP, or SSE), inspects tools live, fuzz-tests inputs, scans source code with AST-based static analysis, audits configs, checks dependencies, and generates reports with OWASP MCP Top 10 compliance scores — all in a single conversation.
With mcp-security-scanner:
You: "Run a full security audit on this MCP server"
Agent: -> rt_inspect_server: 12 tools found, 3 have suspicious descriptions
-> rt_check_tool_poisoning: 2 tools match poisoning patterns (hidden instructions)
-> rt_check_ansi_injection: 1 tool has ANSI escape sequences in description
-> sast_scan_directory: 4 command injection sinks, 2 SSRF vectors found
-> sast_hardcoded_secrets: 1 API key hardcoded in config.ts
-> cfg_auto_discover: 3 MCP configs found, 1 has oversharing
-> dep_check_typosquatting: 1 suspicious package name (1 edit from popular pkg)
-> report_owasp_compliance: Score 4.2/10 — MCP01, MCP03, MCP05 violations
-> "This server has critical security issues:
2 tool poisoning patterns detected — hidden prompt injection
in tool descriptions. 4 command injection sinks in source
with unsanitized user input flowing to child_process.exec().
1 hardcoded API key. 1 suspected typosquatting dependency.
OWASP MCP compliance: 4.2/10. Immediate remediation needed."No API keys. No external calls. Everything runs locally. 100% privacy. Supports stdio, HTTP, and SSE transports.
Existing tools check one narrow thing. mcp-security-scanner gives your AI agent end-to-end MCP security analysis across all attack surfaces.

- 'file_read' tool has hidden instruction in description:
