jefflyt Mandate 2.1.5 Code Static Evaluation Skill
Mandate
- ID: 2.1.5
- Title: Just-in-Time (JIT) and Identity-Based MCP Authentication
Mitigates
- ASI03 Identity and Privilege Abuse
- MCP05 Client Security Considerations
- MCP06 Server Discovery and Verification
Inputs
- Repository root path.
- Tech stack/language map.
- Optional architecture notes if provided.
Workflow
- Scope relevant code surfaces tied to this mandate.
- Run mandate-specific static checks and trace source-to-sink/control paths.
- Extract exact evidence with file/line references.
- Classify each control as implemented, partial, or missing.
- Produce partial-confidence findings and list required runtime/process evidence for closure.
Mandate-Specific Static Method
- Locate MCP auth flows and token exchange logic.
- Verify OAuth 2.1/OIDC/PKCE usage patterns in user-driven authorization paths.
- Verify scope minimization in token request/usage code.
- Flag static credentials or long-lived tokens used for MCP server access.
- Verify code paths for token revocation and session termination.
- Emit findings by server integration and auth flow weakness.
Output Contract
Return a single structured result with:
- mandate_id, mandate_title
- static_status: implemented|partial|missing
- confidence: low|medium|high (static-only confidence)
- evidence: list of file/line findings
- gaps: unresolved items requiring operational proof
- next_evidence_requests: runtime/process artifacts needed
Guardrails
- Avoid final compliance pass/fail using code alone.
- Mark assumptions explicitly.
- Prefer deterministic checks over heuristics when possible.
