TL;DR: Cursor and Oasis are framing agentic IDE security around just-in-time, policy-based control, because agent actions now execute commands, call MCP tools, and touch internal systems in ways that create audit and approval gaps, according to Oasis Security. The security problem is no longer autocomplete, it is governing runtime execution before developer velocity turns into untracked access drift.
NHIMG editorial — based on content published by Oasis Security: Oasis x Cursor: Governing Agentic Execution in the IDE
Questions worth separating out
Q: How should security teams govern AI agents inside the IDE?
A: Security teams should treat IDE agents as non-human identities that need scoped permissions, runtime policy checks, and immediate revocation after task completion.
Q: Why do agentic IDEs create different access risks from normal developer tools?
A: Agentic IDEs create different access risks because the software can execute commands and call tools, not just assist a user.
Q: What breaks when AI agent access is broader than the task it is trying to complete?
A: When agent access is broader than the task, the identity can touch systems, data, and tools that were never necessary for the work.
Practitioner guidance
- Move policy into the agent execution path Place enforcement before MCP calls and command execution so the decision happens before access is consumed.
- Treat agent sessions as ephemeral identities Assign task-scoped access to each session, limit it to the minimum tool set required, and revoke it immediately after the task completes.
- Separate telemetry from governance Log agent actions, tool use, identity attribution, and data movement in a central control plane so review and response are possible after the session.
What's in the full article
Oasis Security's full blog covers the operational detail this post intentionally leaves for the source:
- The hook configuration pattern for intercepting pre-MCP execution in Cursor.
- The logging payload fields used to turn agent actions into central audit records.
- The policy decision states available to security teams, including allow, warn, step-up, and deny.
- The enterprise Shadow AI dashboard concept used to correlate identity, policy, and tool usage.

AI IDE governance collapses when execution is treated as autocomplete. The article shows that the risky moment is not code suggestion but command execution, tool invocation, and internal system access. That means the control model built for human developers and static integrations is already behind the behaviour of agentic IDEs. Practitioners should treat agent actions as governed identity events, not just productivity output.
A few things that frame the scale:
- The average estimated time to remediate a leaked secret is 27 days, despite 75% of organisations expressing strong confidence in their secrets management capabilities, according to The State of Secrets in AppSec.
- Only 44% of developers are reported to follow security best practices for secrets management, which shows how quickly governance assumptions weaken at the point of use.
A question worth separating out:
Q: How do IAM and PAM teams handle approval for high-risk agent actions?
A: IAM and PAM teams should require explicit step-up approval for production access, destructive commands, and sensitive data movement, then revoke that privilege immediately after the session. The goal is to make the agent's authority temporary, attributable, and narrow enough to survive audit and incident review.
