AI agents call tools_documentation to retrieve information from n8n-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves documentation and guides. It is a pure read operation with no side effects, no data modification, and no execution of workflows or commands. Misuse potential is minimal as it only returns informational content.
From the tool's definition Get documentation for n8n MCP tools. Call without parameters for quick start guide. Use topic parameter to get documentation for specific tools.

Get documentation for n8n MCP tools. Call without parameters for quick start guide. Use topic parameter to get documentation for specific tools. Use depth=. It is categorised as a Read tool in the n8n-MCP MCP Server, which means it retrieves data without modifying state.
Register the n8n- MCP server in PolicyLayer and add a rule for tools_documentation: 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 n8n-MCP. Nothing to install.
tools_documentation is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the tools_documentation 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.
Set action: deny in the PolicyLayer policy for tools_documentation. 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.
tools_documentation is provided by the n8n- MCP server (mohsin-zaheer/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
