Why it matters
MCP tool output is an under-audited attack surface, and framing indirect prompt injection as 'SSRF for text' gives defenders and bug hunters a concrete mental model to identify where agent tools ingest attacker-controlled content.
Part 3 of an MCP bug bounty guide by Abhishek meena frames MCP prompt injection as analogous to SSRF: tool outputs (URLs, files, emails, API responses) are attacker-controlled text that the model reads and treats as instructions. The write-up explains how to find, exploit, and argue indirect prompt injection via tool output, with sanitized PoCs referenced.
