Bloqarl | Zealynx(@TheBlockChainer):I built this MCP checklist around a mistake I keep seeing in agent systems: reviewing tools one by one. That misses what the agent can do after capabilities are combined. My first pass is simple: draw every path from untrusted input to a sensitive source, then to an execution or outbound sink. Filesystem + network is the obvious example, but Git + shell or browser + credentials can be just as important. The 24-check review surface is public here:

The dangerous capability in an MCP setup may not belong to any single tool. A filesystem server can read data. A network server can send data. Together, they can create an exfiltration path even if each one looks acceptable in isolation. That is why MCP reviews need a capability map across servers, not just a checklist per tool. Zealynx's public MCP security checklist covers that combined surface alongside command execution, context poisoning, credentials, supply chain, SSRF, and audit logging. Use all 24 checks free:
