run_sca_scan · DevSecOps MCP Server MCP: Risk & Policy

WHAT IT DOES

What run_sca_scan does on DevSecOps MCP Server

AI agents invoke run_sca_scan to trigger actions in DevSecOps MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why run_sca_scan needs a policy

SCA scans execute external security analysis tools against specified code/dependencies and generate reports with results that depend on user-supplied arguments (target repository, scan scope, etc.). This is an Execute action rather than Read because it triggers external processes whose side effects (network requests, file I/O, report generation) are operations that depend on arguments.

From the tool's definition Tool performs 'Execute SCA (Software Composition Analysis) scan' - a scanning operation that analyzes dependencies and triggers external security analysis tools (Trivy and similar), with effects dependent on the scan parameters and target specified.

Verdict

run_sca_scan Rate-limited

run_sca_scan stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about run_sca_scan

What does the run_sca_scan tool do? +

Execute SCA (Software Composition Analysis) scan. It is categorised as a Execute tool in the DevSecOps MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on run_sca_scan? +

Register the DevSecOps MCP Server MCP server in PolicyLayer and add a rule for run_sca_scan: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches DevSecOps MCP Server. Nothing to install.

What risk level is run_sca_scan? +

run_sca_scan is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit run_sca_scan? +

Yes. Add a rate_limit block to the run_sca_scan rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block run_sca_scan completely? +

Set action: deny in the PolicyLayer policy for run_sca_scan. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides run_sca_scan? +

run_sca_scan is provided by the DevSecOps MCP Server MCP server (jesusdavidquarksoft/mcp_security). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
