Risk Summary
Needs ApprovalDep Visibility plus Excessive Permissions raises enough risk that this tool should not be auto-trusted.
Potential impact: This finding indicates the tool should be reviewed before it is trusted.
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 (64)
tool declares exec permission
n8n_get_workflown8n_delete_workflown8n_activate_workflown8n_deactivate_workflown8n_execute_workflown8n_list_executionsn8n_get_executionn8n_delete_executionn8n_retry_executiontool declares network permission
n8n_retry_executionFix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.
n8n_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.

n8n_create_credentialFix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.
tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration
n8n_get_workflown8n_delete_workflown8n_activate_workflown8n_deactivate_workflown8n_execute_workflown8n_list_executionsn8n_get_executionn8n_delete_executionn8n_retry_executionFix: 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.
tool declares http permission
n8n_activate_workflown8n_execute_workflowFix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.
Tool did not expose metadata.dependencies or repo_url, so supply-chain coverage is limited.

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-mcp-server"Adjust the package name if your npm registry name differs from the tool ID. View source
