Free Scoping CallMCP and Agent Code Review delivery and security model
AI security review for MCP servers, agent runtimes, tool manifests, permission models, and production action boundaries across code and configuration.
Focus areas
- MCP tool manifest and schema validation
- Agent identity and tool permission scope
- Confused deputy and tool argument injection risk
- Audit log, approval gate, and rollback behavior
Delivery notes
- Findings connect MCP manifest, tool call, and code path
- Action impact is explained through controlled scenarios
- Remediation maps to permission narrowing and approval flow
Decision matrix
MCP and Agent Code Review is not just a service label; it states how each control is validated and which evidence is expected at closure.
| Control | Decision question | Validation | Expected evidence |
|---|---|---|---|
| MCP tool manifest and schema validation | Does MCP tool manifest and schema validation create real risk? | Validated against the relevant code, request, configuration, or runtime behavior in Source Code Review. | Findings connect MCP manifest, tool call, and code path |
| Agent identity and tool permission scope | Does Agent identity and tool permission scope create real risk? | Validated against the relevant code, request, configuration, or runtime behavior in Source Code Review. | Action impact is explained through controlled scenarios |
| Confused deputy and tool argument injection risk | Does Confused deputy and tool argument injection risk create real risk? | Validated against the relevant code, request, configuration, or runtime behavior in Source Code Review. | Remediation maps to permission narrowing and approval flow |
| Audit log, approval gate, and rollback behavior | Does Audit log, approval gate, and rollback behavior create real risk? | Validated against the relevant code, request, configuration, or runtime behavior in Source Code Review. | Findings connect MCP manifest, tool call, and code path |
What if MCP tool manifest and schema validation fails?
Eresus maps this area to real user-flow or delivery-pipeline impact, so the finding is not left as a generic technical label.
What if Agent identity and tool permission scope fails?
Eresus maps this area to real user-flow or delivery-pipeline impact, so the finding is not left as a generic technical label.
What if Confused deputy and tool argument injection risk fails?
Eresus maps this area to real user-flow or delivery-pipeline impact, so the finding is not left as a generic technical label.

Frequently Asked Questions
What decision does MCP and Agent Code Review clarify?
MCP and Agent Code Review clarifies exploitability, affected workflows, and release impact for Source Code Review with evidence rather than scanner noise.
What evidence is included in MCP and Agent Code Review?
Findings connect MCP manifest, tool call, and code path Also, Action impact is explained through controlled scenarios. Retest criteria and ownership notes are included for closure.
How is this different from an automated scanner report?
Automated findings are not forwarded as-is; false positives are removed, abuse paths are proven, and remediation priority is explained.
