TL;DR: MCP vulnerabilities can turn agent memory into a trust boundary failure, according to Akto. Model Context Protocol workflows need provenance and transfer checks before context is allowed to shape API calls or other privileged actions.
Editorial analysis by NHI Mgmt Group, based on content published by Akto: “MCP Protocol Security Vulnerabilities: What You Need to Know”.
Key questions
Q: Why do unverified context transfers create risk in agentic AI systems?
A: Unverified transfers let one agent inherit context from a source it cannot truly authenticate, so a spoofed or compromised handoff can become a delegated trust decision.
Q: How do security teams detect context inflation or shadow memory abuse?
A: Teams should watch for unusual growth in memory size, entry count, and update frequency, then compare context snapshots at checkpoints to spot hidden additions or overwrites.
Q: What breaks when MCP context is not provenance-checked?
A: When MCP context lacks provenance checks, agents can treat injected or overwritten memory as trusted state and carry that corruption into later decisions.
Practitioner guidance
- Enforce context provenance checks Require signatures, checksums, or origin stamps on memory entries before agents can reuse or propagate them across steps.
- Limit prompt persistence across sessions Define which prompts, intermediate states, and execution traces may survive task boundaries, and block default carry-forward for high-risk workflows.
- Audit context deltas at runtime Compare memory snapshots at checkpoints to detect overwrites, inflation, or hidden additions that would not appear in normal logs.
Bottom line: MCP vulnerabilities show that agent memory can become a trust boundary failure, not just a reliability issue.

MCP is becoming an identity problem, not just an AI plumbing problem: once memory drives API use and task continuation, the trust boundary shifts from the model response to the context object itself. That means provenance, persistence, and transfer rules are now part of access governance, especially where autonomous agents act on behalf of people or systems. Practitioners should treat context as an identity-bearing artefact.
A few things that frame the scale:
- Gartner predicts that by the end of 2026, 40% of enterprise apps will feature task-specific AI agents.
A question worth separating out:
Q: Who is accountable when agent memory causes an unauthorised action?
A: Accountability should sit with the programme that owns the agent’s authority, data access, and runtime controls. For regulated environments, that means mapping ownership to IAM, AI governance, and audit functions, then proving that context provenance, transfer rules, and retention controls were enforced.
