TL;DR: AI coding assistants are reading project files, environment variables, and MCP configurations with privileges that can expose secrets or exfiltrate them externally, according to Knostic. The real issue is not autocomplete accuracy but privilege scope, because developer-side AI tools now behave like privileged software components with broader access than most teams assume.
NHIMG editorial — based on content published by Knostic: AI coding assistants and the quiet privilege problem inside the IDE
By the numbers:
- Only 44% of organisations are currently using a dedicated secrets management system.
Questions worth separating out
Q: How should security teams govern AI coding assistants that can read local secrets?
A: Treat the assistant as a privileged non-human identity inside the development environment.
Q: Why do AI coding tools increase the risk of secret leakage in developer environments?
A: They expand the trust boundary from code completion to context ingestion and action.
Q: What breaks when secrets are stored in MCP or IDE configuration files?
A: Those files stop being harmless metadata and become credential containers that assistants can read and reuse.
Practitioner guidance
- Remove secrets from developer-local configuration Move API keys, tokens, and other credentials out of .env files, MCP JSON, and IDE-specific config into vault-backed injection paths and OS-level secret managers.
- Restrict assistant access by workspace and file type Apply least privilege to AI coding tools so they cannot recursively inspect unrelated directories, hidden files, or production-adjacent paths.
- Monitor tool invocation and outbound patterns Log file reads, shell calls, and network-bound actions taken by assistant-integrated workflows, then alert on unusual sequences such as reading secrets followed by DNS or external request activity.
What's in the full article
Knostic's full article covers the operational detail this post intentionally leaves for the source:
- Examples of AI coding assistant file reads and .env exposure patterns that help teams map real risk to their own developer environments.
- Specific MCP and IDE configuration pitfalls that can turn local tool setup into an implicit secret store.
- The described DNS-based exfiltration and prompt injection behaviours that show how assistant toolchains can be abused in practice.
- Practical remediation themes for isolating assistant context, controlling plugin access, and reducing exposure in modern dev workflows.

AI coding assistants are non-human identities with privileged context access, not harmless developer plugins. They read files, interpret instructions, and act through local tools, which places them squarely inside NHI governance. That means the question is not whether the assistant is useful, but whether its access is governed as if it can read and reuse sensitive material. Practitioners should treat these tools as governed identities in the software supply chain.
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 organisations are currently using a dedicated secrets management system, according to The 2024 State of Secrets Management Survey.
A question worth separating out:
Q: Who is accountable when an AI assistant leaks secrets from the IDE?
A: Accountability should sit with the team that owns the assistant integration, its configuration, and its data boundaries. Human developers may trigger the workflow, but the exposed secret usually reflects a governance failure in tool access, lifecycle control, and monitoring. Existing IAM and PAM ownership models need to include AI developer tooling.
