TL;DR: AI-assisted development only stays secure when identity context is explicit, current, and tightly scoped, according to Descope. Cursor and Windsurf become more reliable when developers feed them rules files that encode Descope SDK usage, architectural intent, and supported auth models, reducing context switching while improving correctness for authentication, API authorization, OAuth token handling, and MCP server access.

Questions worth separating out
Q: How should security teams govern AI coding tools that create non-human identities?
A: Teams should treat every AI coding tool that can authenticate or call systems as a non-human identity with an owner, a scope, and a lifecycle.
Q: Why do AI code editors create risk for authentication and authorization logic?
A: They create risk when they generate plausible code without understanding trust boundaries.
Q: What breaks when AI assistants generate identity flows without rules files?
A: Without rules files, the assistant may mix unsupported flows, choose the wrong session method, or bypass architecture decisions that were meant to constrain access.
Practitioner guidance
- Embed approved identity rules into editor workflows Store reviewed .cursor and .windsurf rules files in the project root and keep them aligned with approved authentication, session, and authorization patterns.
- Separate human, app, and agent access patterns Document distinct implementations for user login, API authorization, and MCP tool access so the assistant cannot blur those boundaries.
- Require backend session verification for every protected route Use backend validation rather than trusting client-side token handling suggestions from the editor.
What's in the full article
Descope's full blog post covers the implementation detail this analysis intentionally leaves for the source:
- The exact Descope SDK patterns referenced in Cursor and Windsurf rules files for sign-in, session handling, and authorization.
- Examples of how to structure .cursor/rules.mdc and .windsurf/rules.mdc so the IDE follows approved identity logic.
- Operational guidance on when to use hosted Flows, embedded Flows, inbound apps, and outbound apps in development workflows.
- A demo flow showing how the editor applies context to a Next.js authentication build.

AI code editors are now part of the identity control plane. When a model can generate authentication, session handling, and API authorization code inside the IDE, it becomes an implementation pathway for identity policy, not just a productivity tool. That means bad context can hard-code bad access decisions at development time. Practitioners should treat editor rules as part of IAM governance, not developer convenience.
A few things that frame the scale:
- 98% of companies plan to deploy even more AI agents within the next 12 months, despite documented rogue behaviour in 80% of current deployments, according to AI Agents: The New Attack Surface report.
- Only 52% of companies can track and audit the data their AI agents access, leaving 48% with a complete blind spot for compliance and breach investigation.
A question worth separating out:
Q: How should security teams govern MCP tool access in enterprise environments?
A: Security teams should bind MCP tool access to enterprise identities, entitlements, and lifecycle state before a request reaches production tools. A gateway can enforce policy at the edge, but governance only exists when the identity system knows who is calling, what they are allowed to do, and whether approval or offboarding has already occurred.
