Harden MCP retries and rate-limit handling with route budgets, quota owners, idempotency guards, backoff evidence, exhausted-budget denials, and receipts.

Prevent SSRF in MCP fetch and URL tools with URL parsing, DNS/IP classification, redirect containment, credential-lane isolation, typed denials, and audit recei

Before an AI agent repeats a paid API call, make one route, one budget owner, one credential rail, one denied neighbor, and one receipt boring enough to audit.

A copy-paste MCP threat model for production agent tools: route, caller, authority surface, credential lane, budget owner, denied neighbor, receipts, and recove
