Risk Summary

Needs Approval

Supply Chain CVEs plus Excessive Permissions raises enough risk that this tool should not be auto-trusted.

Potential impact: Known dependency vulnerabilities can be exploited during install or runtime and widen the attack surface.

Recommended action: Keep this tool behind manual approval and avoid unattended runs until the risky capabilities are narrowed or removed.

Suggested policy: keep this tool behind manual approval, do not allow unattended runs, and re-scan after narrowing risky permissions.

Security Findings (45)

  • HighAS-004

    📦Supply Chain CVEs (OSV) ×23

    GO-2026-5024 in golang.org/x/[email protected]: Invoking integer overflow in NewNTUnicodeString in golang.org/x/sys/windows (upgrade to 0.44.0)

    Fix: Upgrade or replace the vulnerable dependency. Pin all dependency versions and enable automated CVE scanning (Dependabot or OSV Scanner).

  • HighAS-002

    ⚠️Excessive Permissions ×4

    tool declares exec permission

    execute_workflowlist_executionsget_executiondelete_execution

    Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.

  • HighAS-003

    🔀Scope Mismatch ×2

    tool name "list_executions" implies read-only operation but declares exec permission

    list_executions

    tool name "get_execution" implies read-only operation but declares exec permission

    get_execution

    Fix: Ensure tool names, descriptions, and permission declarations are internally consistent. Use explicit naming conventions that fully reflect actual capabilities.

  • HighAS-010

    🔑Insecure Secret Handling

    get_credential_schema:input parameter "credentialType" appears to accept a secret or credential

    Fix: Avoid accepting raw credentials as input parameters. Use secret managers (e.g. 1Password CLI, AWS Secrets Manager) and ensure credentials are never logged or stored in agent traces.

  • MediumAS-002

    ⚠️Excessive Permissions ×11

    tool declares fs permission

    create_workflowupdate_workflowdelete_workflowcreate_workflow_and_activatedelete_executioncreate_tagupdate_tagdelete_tagupdate_workflow_tagscreate_credentialdelete_credential

    Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.

  • LowAS-011

    ℹ️Missing Rate-Limit / Timeout ×4

    tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration

    execute_workflowlist_executionsget_executiondelete_execution

    Fix: Declare explicit rate-limit, timeout, and retry configuration for all network and execution tools. Implement exponential back-off and surface resource state to the calling agent.

Scan this tool yourself

Reproduce this audit locally, integrate into CI, or let your agent audit its own tools.

Install once, then scan any MCP server:

$ curl -sfL https://raw.githubusercontent.com/AgentSafe-AI/tooltrust-scanner/main/install.sh | bash
$ tooltrust-scanner scan --server "npx -y makafeli-n8n-workflow-builder"
