Risk Summary

Safe With Normal Controls

Dep Visibility is the main signal, but overall risk remains within an acceptable range.

Potential impact: This finding indicates the tool should be reviewed before it is trusted.

Recommended action: No high-risk findings were detected in this scan, but you should still apply least-privilege defaults and rescan after changes.

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

Security Findings (44)

  • 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.

  • LowAS-011

    ℹī¸Missing 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.

  • InfoAS-014

    ℹī¸Dependency Inventory Unavailable ×23

    No metadata.dependencies or repo_url were exposed by this MCP server, and no local project manifest could be inferred from the launch command.

    Fix: Review and remediate the identified issue.

  • InfoAS-002

    ⚠ī¸Excessive Permissions ×14

    declared capabilities: filesystem access

    create_workflowupdate_workflowdelete_workflowcreate_workflow_and_activatecreate_tagupdate_tagdelete_tagupdate_workflow_tagscreate_credentialdelete_credential

    declared capabilities: code/command execution

    execute_workflowlist_executionsget_execution

    declared capabilities: code/command execution, filesystem access

    delete_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.

  • InfoAS-010

    🔑Insecure Secret Handling

    get_credential_schema:input parameter "credentialType" accepts a credential (informational; not evidence of insecure handling)

    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.

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 n8n-workflow-builder"

Adjust the package name if your npm registry name differs from the tool ID. View source
