MCP Security Audit
Your MCP Server Gives AI Agents the Keys. Check the Locks.
Quick answer: Codersarts AI offers fixed-price security audits for MCP servers, ChatGPT plugins and Claude connectors. We test authentication, permissions, prompt injection, tool poisoning, data exposure and logging, then deliver a prioritised fix list and a procurement-ready summary. Prices start at $1,500, with results in 3–10 days.
One weak spot — over-broad permissions, a leaked token, an instruction hidden in a document — can turn a helpful assistant into a data leak. We review your server the way an attacker and an enterprise security reviewer would.

THE PROBLEM
Why Do MCP Servers Need a Security Audit?
OX Security's October 2026 study of 15,465 public MCP servers found no vetting on major marketplaces, servers routed through personal tunnels, and expired domains anyone could register to take over a server's identity.
In the same month, Radware (October 14) and Celigo (October 20) launched MCP protection and governance products. Enterprise buyers are starting to ask about MCP security during procurement — be ready with answers.
WHAT WE CHECK
What Does the Audit Cover?
Authentication — OAuth 2.1 implementation, token storage, expiry and revocation
Authorization — scopes, tenant isolation and access beyond what the user should have
Prompt injection — whether documents, emails or tickets can make the agent misuse tools
Tool poisoning — hidden instructions or misleading tool metadata
Dangerous actions — writes, deletes and bulk operations without confirmation
Data exposure — sensitive data returned to the AI that doesn't need to be
Infrastructure — domains, hosting, transport security and rate limits
Logging and response — whether you can see, trace and stop misuse

FAQ
Frequently Asked Questions
How much does an MCP security audit cost? $1,500 for a Quick Scan, $3,000 for a Standard audit with attack testing, and $4,500–$6,000 for multi-server environments.
Do you need our source code? It gives the most thorough review, but we can audit from a test environment and documentation alone.
Is this a penetration test? It's a focused review of your AI integration layer. It complements, not replaces, a full application pen test.
Will the report help with enterprise security questionnaires? Yes. Every audit includes a one-page summary written for procurement and security reviewers.
Can you fix the issues too? Yes — quoted separately or covered by an MCP Server Maintenance plan.
How quickly can you start? Usually within 3 business days of receiving access.
