MCP Penetration Testing

MCP Penetration Testing is a security assessment of Model Context Protocol servers, tools and integrations. It checks whether attackers can abuse tools, steal tokens, manipulate context or trigger unauthorised actions.

Blacklock tests token mismanagement, secret exposure, tool poisoning, command injection, privilege escalation, weak authentication, lack of audit logging, shadow MCP servers and context over-sharing.

MCP connects AI applications to tools, data and business systems. Weak permissions or unsafe tool design can allow an attacker to manipulate an AI system into accessing data or performing actions beyond the intended scope.

Yes. Blacklock tests whether malicious prompts, documents or tool outputs can influence MCP tool calls, bypass controls or cause unintended actions.

Access may include MCP server details, test users, tool schemas, API documentation, authentication flows, approved tokens, architecture diagrams and access to a controlled test environment.

Yes. Blacklock can assess internal MCP servers where access is provided through an agreed and controlled testing method.

Yes. LLM testing focuses on model-integrated application behaviour. MCP testing focuses on the protocol layer, tools, permissions, tokens, context sharing and agent-to-tool interactions.

The duration depends on the number of MCP servers,tools, workflows, permissions and integrations in scope. A typical assessment takes several days to two weeks.
