iam-policy-autopilot
IAM Policy Autopilot is an open-source tool (CLI + MCP server) that performs deterministic static analysis of application code to generate baseline AWS IAM identity-based policies (and optionally help fix AccessDenied errors). It targets building/iterating IAM permissions for application roles using local code inspection.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Security posture appears to rely on AWS credential configuration (not described in detail) and careful human review of generated policies. The README emphasizes reviewing/refining and notes limitations (no resource-based policies; runtime resource inference gaps). The MCP server transport supports stdio (default) or HTTP; TLS usage for HTTP is not specified in the provided content.
⚡ Reliability
Best When
You have a relatively deterministic set of AWS SDK calls in the code and you want a fast starting point for IAM identity-based policies that you will review and refine.
Avoid When
Your required permissions depend heavily on dynamic/runtime resource resolution that cannot be inferred from static analysis, or you need non-identity-based policy types (bucket/KMS policies, SCPs, etc.).
Use Cases
- • Generate baseline AWS IAM policy documents from application source code (Python/Go/TypeScript).
- • Use an MCP-enabled AI coding assistant to produce/adjust IAM policies as infrastructure templates are generated.
- • Debug and remediate AccessDenied errors by analyzing denied actions and proposing IAM policy changes.
- • Scope IAM analysis using service hints to reduce unnecessary permissions.
Not For
- • Resource-based policies (e.g., S3 bucket policies, KMS key policies), SCPs/RCPs, or permission boundaries.
- • Correct identification of runtime-dependent resources (e.g., bucket names/ARNs determined only at runtime).
- • Fully automated production policy deployment without human security review.
Interface
Authentication
The MCP server/CLI appears to use AWS credentials to apply/upload/debug policies, but no API-style auth mechanism (API keys/OAuth scopes) is described for the MCP interface itself. Authentication is likely by underlying AWS credential configuration.
Pricing
Open-source; no hosted pricing details provided in the supplied README/manifest.
Agent Metadata
Known Gotchas
- ⚠ Static analysis may over-include permissions when multiple AWS services share similarly named SDK methods; use --service-hints where possible.
- ⚠ The tool does not handle resource-based policies (e.g., S3 bucket policy, KMS key policy) or SCP/RCP/permission boundaries.
- ⚠ Runtime-dependent resource ARNs (e.g., bucket names) may not be inferred, so generated policies may require post-review modifications.
- ⚠ When using the MCP integration, the coding assistant may further modify the policy beyond the static analysis output—review is required before deployment.
- ⚠ fix-access-denied can optionally apply changes (use caution); understand what will be uploaded/applied before granting assistant automation permissions.
