A fixed-fee $3,500 assessment of your MCP server or AI agent — server config audit, prompt injection surface testing, tool permission review, and a prioritised remediation report your engineering team can action this sprint.
Fixed fee · delivered in 5 business days · findings your team can action immediately
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.
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.
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.
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.
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.
Every MCP server and AI agent is different. We map the actual data, tools, and permissions — then test the paths that matter.
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.
Systematic testing of every user-facing input for prompt injection that overrides system instructions, exfiltrates data, or triggers unintended tool calls through your agent.
Malicious instructions planted in documents, emails, or web pages that your agent retrieves through MCP tools — hijacking behaviour through RAG or tool outputs.
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.
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.
Role switches (DAN-style), persona overrides, and safety-guardrail bypasses that let an attacker make your agent take actions it was designed to refuse.
API keys, tokens, and customer data exposed through verbose errors, system prompt leakage, or MCP tool outputs that reach untrusted surfaces.
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.
This simplified scenario shows why every MCP tool call needs a confirmation boundary — and why retrieved content must be treated as untrusted data.

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.
Every assessment ships with these artifacts. No vague PDFs — every finding has a PoC, a fix, and a framework reference.
Board-ready language, risk scoring, and a one-page summary of findings by severity. Drop-in for a board deck.
Full review of your MCP server configuration: tool registrations, authentication, permissions, and exposed endpoints — with specific hardening recommendations.
Every critical and high finding includes the actual prompt or payload that worked, plus the attack chain walkthrough.
Severity × exploitability × business impact, mapped to OWASP LLM Top 10 and OWASP Agentic Security Initiative.
Specific code snippets, config changes, or system prompt rewrites for every finding. Ready to paste into a PR.
How to verify each fix actually holds. Includes a retest engagement option at a discounted rate.
Walkthrough of the findings, live Q&A with your engineering or security team.
Every finding is mapped to a specific framework control so your security, engineering, and compliance teams share one document.
No lengthy onboarding. No ongoing dependency. Just a clear, written report your team can action.
