The MCP attack surface is growing faster than guardrails.

Every MCP server you connect gives your agent tool access to real data. That's the same attack surface an adversary probes — and the window to test it before a breach is closing.

🔌

MCP Is the New Standard

Model Context Protocol is how AI agents connect to tools, databases, and APIs. Every MCP server is a new entry point — and most ship with default permissions and no security review.

🔓

Tool Access = Data Access

An MCP server with read/write access to your database, file system, or email is one prompt injection away from exfiltration. We test the paths that matter before an attacker does.

📈

Agentic Surface Is Exploding

2025 saw a 10× increase in agentic AI deployments. Every new tool, every new integration re-opens the attack surface. A one-time audit is a snapshot — but it's the snapshot you need before you ship.

🎯

Your Bug-Bounty Edge

Led by a researcher with public HackerOne findings and 12+ years in enterprise IT security. We test the same way real adversaries do — not a checklist, but an attack chain.

The attack paths we assess before your agent goes live.

Every MCP server and AI agent is different. We map the actual data, tools, and permissions — then test the paths that matter.

Critical

MCP Server Config Audit

We review your MCP server configuration for insecure defaults, overly permissive tool registrations, missing authentication, and exposed endpoints that let an attacker call tools without authorisation.

OWASP ASI06 · MCP Protocol
Critical

Direct Prompt Injection

Systematic testing of every user-facing input for prompt injection that overrides system instructions, exfiltrates data, or triggers unintended tool calls through your agent.

OWASP LLM01 · OWASP ASI01
Critical

Indirect Injection via MCP Tools

Malicious instructions planted in documents, emails, or web pages that your agent retrieves through MCP tools — hijacking behaviour through RAG or tool outputs.

OWASP LLM01 (indirect) · OWASP ASI02
High

Tool Permission Escalation

Testing whether an attacker can chain MCP tool calls to escalate privileges — reading data from one tool, writing through another, or calling destructive tools without confirmation boundaries.

OWASP ASI06 · OWASP ASI07

Data Exfiltration via Tool Output

Testing whether system prompts, API keys, customer data, or other secrets leak through MCP tool responses, verbose error messages, or model output that reaches downstream systems.

Jailbreak & Persona Bypass

Role switches (DAN-style), persona overrides, and safety-guardrail bypasses that let an attacker make your agent take actions it was designed to refuse.

Credential & API Key Exposure

API keys, tokens, and customer data exposed through verbose errors, system prompt leakage, or MCP tool outputs that reach untrusted surfaces.

Unsafe Output Handling

Harmful, off-brand, or policy-violating model outputs reaching end users or downstream systems without filtering — including code execution, SQL generation, and destructive API calls.

OWASP LLM05

How indirect injection turns an MCP tool into a data leak.

This simplified scenario shows why every MCP tool call needs a confirmation boundary — and why retrieved content must be treated as untrusted data.

Result without guardrails: Token and email exfiltrated via the MCP send_email tool. A 4-line system-prompt fix (treat retrieved content as data, not instructions, and require confirmation for any send_email call) would have blocked it. This is exactly the kind of finding we surface — with the fix.

A report your security team and your engineers will both use.

Every assessment ships with these artifacts. No vague PDFs — every finding has a PoC, a fix, and a framework reference.

Common questions.

What is an MCP security assessment?
An MCP (Model Context Protocol) security assessment is a structured review of your AI agent's server configuration, tool permissions, prompt injection surface, and data access paths. We test the same attack paths an adversary would use — direct injection, indirect injection through retrieved content, tool misuse, and data exfiltration — and deliver a prioritised remediation report.
How is this different from the $750 Risk Review?
The $750 Founding AI Agent Risk Review is a focused, 3-attack-path check on one agent. The $3,500 MCP Security Assessment is a deeper engagement: full server config audit, comprehensive injection surface mapping, tool permission review across all connected services, and a written remediation report with specific code and config fixes.
How long does the assessment take?
The MCP Security Assessment is delivered within 5 business days of receiving test access. A 30-minute debrief call is included to walk through findings.
Do you need production access?
No. We work against a test environment, a read-only API key, or a sandbox. Your production stays untouched throughout the engagement.
What if the assessment finds no critical issues?
You still receive a written account of what was tested, the controls that held, and the risks to monitor as your agent changes. A clean result is useful evidence, not a failed engagement.
What happens after the assessment?
After the assessment, you can expand into a Continuous AI Red-Team Retainer ($2K/mo) for quarterly re-tests, prompt-injection regression checks, and CVE monitoring. The assessment findings become the baseline for the retainer's regression set.
