MCP Server Security — Harden Model Context Protocol Integrations
Your MCP server connects AI agents to your entire business. Is it locked down?
Bachao.AI audits Model Context Protocol servers for exposed tools, weak auth, privilege escalation, and prompt injection paths that reach your databases, files, and APIs.
Complete MCP server security coverage
Tool definitions, authentication, indirect injection, and data leakage — every MCP attack surface tested.
Tool Definition Audit
Every tool exposed by your MCP server is reviewed for overprivileged parameter access, missing input validation, and unintended capabilities that could be abused by a manipulated AI agent.
Authentication & Authorisation
MCP server authentication mechanisms are tested for weak tokens, missing rate limits, unauthenticated tool calls, and session handling vulnerabilities.
Prompt Injection via Tool Responses
Tool responses that return user-controlled content are tested as indirect prompt injection vectors. A malicious database record or API response can hijack agent behaviour.
Data Leakage Prevention
Test whether your MCP server leaks sensitive data — internal file paths, database schemas, system architecture details, or user PII — through tool response content or error messages.
How the MCP security audit works
Submit, audit, test, harden — 48 hours from config to report.
Provide your MCP server schema file, tool definitions, and transport configuration. Bachao.AI maps every tool, parameter, and data access path.
Each tool is reviewed for principle of least privilege violations — tools that expose more access than their stated purpose requires are flagged with specific remediation.
Authentication mechanisms and tool response content are tested for weak tokens, unauthenticated endpoints, and indirect prompt injection vectors from third-party or user data.
A prioritised finding report with OWASP LLM Top 10 mapping, severity ratings, and code-level fix suggestions is delivered within 48 hours.
Generic VAPT vs dedicated MCP security audit
Generic penetration testing has no tooling for MCP-specific attack vectors.
| Generic VAPT | Bachao.AI | |
|---|---|---|
| Tool permission review | Not covered | Every tool audited for least-privilege violations |
| Indirect injection testing | Not applicable | Tool responses tested as injection vectors |
| Auth testing | Generic auth checks | MCP-specific token, rate-limit, and session tests |
| Data leakage | App-layer only | Error messages, schemas, file paths, PII in responses |
| Framework mapping | CERT-In only | OWASP LLM07/LLM08 + MITRE ATLAS + CERT-In |
| Turnaround | 2–4 weeks | 48 hours (standard) / 5 days (complex multi-server) |
Start free. Scale when the risk is real.
Every MCP Server Security engagement is scoped to your actual attack surface — no flat subscription that pretends every project is the same. Our automated approach typically costs materially less than traditional VAPT providers for equivalent coverage.

Frequently asked questions
Everything you need to know about MCP server security testing.
What is an MCP server and why does it need security testing?
Model Context Protocol (MCP) is an open standard that allows AI agents (like Claude, GPT-4o) to connect to external tools and data sources — file systems, databases, APIs, calendars. An MCP server defines what tools are available and how they're called. A vulnerable MCP server can give an AI agent — or an attacker who manipulates the agent — unintended access to your systems.
What specific vulnerabilities does Bachao.AI test in MCP servers?
We test for: unauthenticated tool access, overprivileged tool parameters (e.g. a read tool that can actually write), indirect prompt injection via tool responses, sensitive data exposure in error messages, tool name confusion attacks, and missing rate limiting on expensive tool calls.
Do I need to give Bachao.AI access to my production systems?
No. For most audits, you provide your MCP server configuration file (schema and tool definitions) and we conduct a whitebox review. For dynamic testing, we set up an isolated test environment — we never run attack payloads against production.
How long does an MCP security audit take?
A standard MCP server audit — covering tool definitions, auth, and prompt injection paths — takes 48 hours from submission to report. Complex multi-server or custom transport configurations may take up to 5 business days.
Is there a standard compliance framework for MCP security?
MCP security standards are still emerging. Bachao.AI tracks Anthropic's MCP security guidelines, OWASP LLM Top 10 (which covers tool-use attacks), and NIST AI RMF. Our reports map findings to these frameworks alongside CERT-In compliant documentation.
