Quick Overview
This n8n workflow sets up a central system to control how AI agents access and use business tools. It uses the Model Context Protocol (MCP) to make all requests consistent, uses Claude AI to understand the context and make decisions, and uses Google Sheets to store access rules (RBAC), session information, and audit logs. The workflow checks each request, makes sure data is handled correctly, sends tasks to different business systems, and gathers the results, all while protecting sensitive information.
What This Workflow Does
This workflow creates a secure and scalable way to manage AI in your company. It creates a single, consistent way for AI agents to ask for access to tools across different business systems. It makes sure data is handled based on permissions and uses Claude AI to understand the context of each request. This gives you one central place to manage all the different AI agents your company uses.
How It Works
The workflow runs in several steps:
Receive AI Agent Request
It all starts when an AI agent sends a request to a special webhook. This is the front door for all AI tasks.
Enterprise Auth & RBAC
Next, the workflow checks the security token (JWT) in the request. It looks up the user’s permissions and makes sure different teams' data is kept separate, so agents can only access what they're allowed to.
Context Assembly
Then, the workflow gathers all the necessary background information. This includes the user's profile, company rules, current activity, and past actions. This full picture helps the AI make better decisions.
Claude AI Orchestration
Claude AI analyzes all this information to figure out the best plan. It chooses the right set of tools, confirms what the agent is trying to do, and decides how to carry out the task. This makes sure the AI's actions fit with the company's goals and rules.
Policy Enforcement Engine
Before running anything, the workflow checks it against company policies. This includes rules about data sensitivity, preventing data leaks, and restrictions based on location or time of day. This is a key safety check.
Multi-System Tool Send
The workflow then sends the planned tasks to the right business systems, like your CRM, ERP, or data warehouse. It can run multiple tasks at the same time if the plan allows it.
Response Aggregation
Once the tools are done, the workflow combines the results from all the different systems. It cleans up the data and removes sensitive information before creating the final answer.
Compliance Logging
Everything that happens is logged for auditing purposes. This log tracks where data comes from and what happens to it, making all AI actions clear and accountable.
Return Enriched Context
Finally, the workflow sends a standardized response back to the AI agent. This response explains the steps taken, so the agent understands how its request was handled.
Prerequisites
To use this workflow, you'll need:
An active n8n instance.
Access to these apps and their login details:
Agent: For the Claude AI Contextual Orchestration and Tool Planning node.
Email Send: For sending policy and security alerts.
Google Sheets: To store RBAC policies, session registries, and audit logs.
Http Request: To send requests to CRM, ERP, and Analytics systems.
Lm Chat Anthropic: For integrating Claude AI.
Credentials for these services:
Anthropic API: An API key to connect to Claude AI.
Google Sheets OAuth2: An OAuth2 credential to allow n8n to read from and write to your Google Sheets.
Service-specific API credential (if configured): For your enterprise systems (CRM, ERP, Analytics) accessed via HTTP Request nodes. This would typically be a bearer token or similar.
SMTP: An SMTP credential for sending emails.
A JWT Secret to check security tokens (you'll set this up inside a Code node, not as a separate n8n credential).
Google Sheets that are already set up for managing permissions, sessions, and audit logs.
The API addresses (endpoints) for your business systems (like CRM, ERP, Analytics) that will receive the tool requests.

Step-by-Step Setup
Import the Workflow
Download the workflow JSON from the source URL and import it into your n8n instance.
Configure Credentials
For each app listed above, you'll need to add or choose your credentials in n8n:
Anthropic API: Provide your Anthropic API key.
Google Sheets OAuth2: Authenticate with your Google account to grant n8n access to your Google Sheets.
SMTP: Configure your SMTP server details for email sending.
Service-specific API credentials: In the HTTP Request nodes, you'll need to add your own API tokens in the
Authorizationheaders for your CRM, ERP, and Analytics systems.
Populate RBAC Policy Sheet
In your Google Sheet for permissions, you'll need to list out roles, what they can do, and data sensitivity levels. This sheet controls who can access what.
Configure Enterprise System Endpoints
Change the placeholder URLs in the 'Send — CRM System', 'Send — ERP System', and 'Send — Analytics and Data Warehouse' HTTP Request nodes to the real API addresses for your business systems. Make sure the authorization headers in these nodes also have your valid API tokens.
Set Tenant IDs and Organizational Policies
You might need to change some settings in the workflow's Code nodes, like tenant IDs or other company-wide rules, to match how your business is set up. For instance, the 'Enterprise Auth, JWT and RBAC Validation' node has code for checking security tokens and keeping team data separate.
Activate Workflow and Register Webhook
Turn on the workflow in n8n. Then, copy the webhook URL from the 'Receive Enterprise AI Agent Request' node and add it to your AI agent platform. This is the address your AI agents will use to send requests.
Customization Ideas
Improve Permission Rules: Add more specific permissions, use attribute-based controls (ABAC), or connect to an external identity service for better role management.
Connect More Systems: Add more HTTP Request nodes to the 'Multi-System Tool Send' section to connect to other tools like HR systems, ticketing platforms, or your own internal APIs.
Improve Data Protection: Update the data loss prevention (DLP) rules in the 'Aggregate Results and Apply DLP Redaction' node to find and hide specific types of sensitive information that are important to your company.
Use Different Alerts: Send security and compliance alerts to services like Slack, Microsoft Teams, or PagerDuty instead of, or in addition to, email.
Make AI Smarter: Improve the prompt for Claude AI to handle more complex situations, like choosing tools based on real-time data or who the user is.
Add Human Approval: For risky actions flagged by Claude AI, add a step that requires a person to approve it. You could use a task manager or build a simple approval screen for this.
Limitations and Troubleshooting
JWT Validation: The way this workflow checks JWT security tokens is basic. For a live system, you should use a proper JWT library or service to do a more thorough check, including signature validation.
API Endpoints: The HTTP Request nodes for your business systems have placeholder URLs (e.g.,
https://YOUR_CRM_API/api/v2/mcp-send). You need to replace these with the real API addresses for your systems.Credential Management: Make sure you keep API keys and tokens for other systems safe and update them regularly.
Rate Limits: Watch out for API rate limits from services like Anthropic or your CRM. This workflow doesn't have built-in protection for this, so your requests could get blocked if you send too many.
Error Handling: Some nodes are set to continue even if they fail, but for a live system, you'll probably want to add better error handling and automatic retries for when external systems don't respond.
Scalability: If you expect a lot of requests, look into n8n's options for scaling to handle the extra load.
