# Connect Atlan to AI Agents: Automate Access and Group Membership


You want to connect Atlan to an AI agent so your internal systems can independently manage data governance access, provision users, assign roles, and audit SSO group mappings based on historical context. Here is exactly how to do it using Truto's `/tools` endpoint and SDK, bypassing the need to manually wire up dozens of endpoints or maintain fragile API wrappers.

Giving a Large Language Model (LLM) read and write access to your Atlan instance is an engineering headache. You either spend weeks building, hosting, and maintaining a custom connector that understands the vendor's specific data models, or you use a managed infrastructure layer that handles the boilerplate for you. If your team uses ChatGPT, check out our guide on [connecting Atlan to ChatGPT](https://truto.one/connect-atlan-to-chatgpt-manage-user-roles-and-group-governance/), or if you are building on Anthropic's models, read our guide on [connecting Atlan to Claude](https://truto.one/connect-atlan-to-claude-provision-users-and-manage-sso-mappings/). For developers building custom autonomous workflows, you need a programmatic way to fetch these tools and bind them to your agent framework.

This guide breaks down exactly how to fetch [AI-ready tools for Atlan](https://truto.one/what-is-llm-function-calling-for-integrations-2026-guide/), bind them natively to an LLM using LangChain (or any framework like LangGraph, CrewAI, or Vercel AI SDK), and execute complex data governance workflows. For a deeper look at the architecture behind this approach, refer to our research on [architecting AI agents and the SaaS integration bottleneck](https://truto.one/architecting-ai-agents-langgraph-langchain-and-the-saas-integration-bottleneck/).

## Why a [Unified Tool Layer](https://truto.one/best-unified-api-for-llm-function-calling-ai-agent-tools-2026/) Matters for Agent Safety

Before writing a line of integration code, decide what layer your agent talks to. This choice determines how safe your production system will be.

Direct API tools - writing one tool per raw Atlan endpoint - look convenient in a sandbox, but they push provider-specific quirks directly into the LLM's context window. The model has to remember exactly how to format nested payloads, which fields are required for specific resources, and how to handle pagination cursors. Every one of those quirks is a hallucination waiting to happen.

Truto abstracts this away. Every integration on Truto is essentially a comprehensive JSON object that represents how the underlying product's API behaves - a massive map of `Resources` (endpoints) and `Methods` (CRUD operations). Truto takes these methods and provides them as Proxy APIs, handling all the underlying authentication and query parameter processing. 

When solving problems agentically, these Proxy APIs are perfect. You call the Truto `/tools` endpoint, and we return descriptions and JSON schemas for all available Atlan methods. Your agent sees stable, declarative function names like `create_a_atlan_user` and `list_all_atlan_groups`.

This architecture gives you concrete safety wins:

1. **Smaller attack surface for hallucination.** The LLM only ever chooses from stable function names and strict JSON schemas. 
2. **Deterministic input validation.** Invalid arguments are rejected before they hit the Atlan API, so a broken tool call fails fast.
3. **Separation of concerns.** Your LLM framework focuses on reasoning; Truto handles the execution, auth, and state.

## The Engineering Reality of Custom Atlan Connectors

Building AI agents is easy. Connecting them to external SaaS APIs safely is hard. If you decide to build an Atlan connector yourself, you own the entire API lifecycle. The Atlan API introduces several highly specific integration challenges that break standard LLM assumptions.

### The Role GUID Resolution Trap
When an agent wants to provision a new user in Atlan, the human prompt usually says: "Invite sarah@company.com as an admin." If you let an LLM generate the payload directly for Atlan's user creation endpoint, it will naturally try to pass `"role": "admin"`. Atlan will reject this. User creation requires passing the internal role GUID (e.g., `roleId`) for specific personas (`$admin`, `$member`, `$guest`), which must first be retrieved via a separate GET request to the roles service. If you hand-code this integration, you have to write complex custom orchestration logic just to map English role names to internal UUIDs before executing the primary request.

### Strict Group Path Constraints
Atlan enforces aggressive validation on group internal names and paths. The internal name must be unique, entirely lowercase, and include only alphanumeric characters and the underscore. Furthermore, when updating a group via its ID, the payload often requires the `path` attribute to be the internal group name prefixed with a forward slash (`/`). An LLM does not inherently know these string validation rules and will hallucinate uppercase characters or missing slashes, causing continuous 400 Bad Request errors.

### Array-of-Strings Attribute Wrapping
Atlan's group attribute model requires highly specific formatting. Fields like `alias` and `isDefault` are not simple strings or booleans; they must be wrapped as arrays of strings (e.g., `"isDefault": ["true"]`). If a standard [JSON-generating LLM](https://truto.one/what-is-llm-function-calling-for-integrations-2026-guide/) tries to update a group description, it will natively output a string. The Atlan API expects `"description": ["New description"]`. Teaching an LLM to override its native JSON tendencies requires extensive prompt engineering - or you use a strict tool schema that enforces this structure natively.

## Hero Tools for Atlan Automation

Instead of dealing with these quirks manually, you can expose Truto's standardized tools to your agent. Here are the highest-leverage tools available for the Atlan integration.

### list_all_atlan_roles
Retrieves all available workspace roles in Atlan. This is a critical prerequisite tool that the agent must use to discover the correct role GUIDs before attempting to invite or modify a user.
> "Fetch the list of all roles in our Atlan workspace so we can find the GUID for the admin role."

### create_a_atlan_user
Invites a new user to the Atlan workspace. The tool enforces an array structure where each user object requires an email, role, and the specific roleId obtained from the roles list.
> "Invite engineering-lead@ourcompany.com to Atlan. Make sure they are assigned the $admin role using the GUID you just looked up."

### create_a_atlan_group
Provisions a new group. The tool schema explicitly requires an internal name that is lowercase and alphanumeric with underscores, and forces the alias into an array of strings. This prevents the LLM from sending invalid formatting.
> "Create a new Atlan group called 'data_engineering_team'. Set the alias to 'Data Engineering' and make sure the internal name fits the naming constraints."

### atlan_users_add_to_groups
Assigns an existing user to one or more groups. The agent only needs the user's GUID and an array of group identifiers, and Truto normalizes the API request.
> "Add the user with ID 98765-abcd to the data_engineering_team group."

### atlan_groups_get_members
Lists all users that are currently members of a specific Atlan group. This is vital for auditing access or checking if a user is already in a group before attempting to add them.
> "Check who is currently a member of the external_contractors group in Atlan."

### create_a_atlan_sso_group_mapping
Links an external identity provider (IdP) group to an internal Atlan group. This is the cornerstone of automated access governance, ensuring that when an IT admin updates an Okta group, Atlan mirrors the permissions.
> "Create an SSO group mapping linking our Okta 'Data_Scientists' group to the internal Atlan 'data_science' group."

## Workflows in Action

When you provide these [unified tools](https://truto.one/best-unified-api-for-llm-function-calling-ai-agent-tools-2026/) to an agent framework, you can orchestrate multi-step data governance tasks completely autonomously. Here is how three common scenarios execute in production.

### Scenario 1: Automated Employee Data Onboarding
When a new data engineer joins the company, the agent needs to provision their Atlan account with the correct access rights.

> "We have a new hire, alex@company.com. Invite them to Atlan as a $member, and add them to the 'data_engineering_team' group."

1. The agent calls `list_all_atlan_roles` to find the internal roleId for `$member`.
2. The agent calls `create_a_atlan_user`, passing alex@company.com, the `$member` role, and the retrieved roleId.
3. The agent calls `atlan_groups_get_by_name` to search for the group alias "data_engineering_team" and retrieves the group's GUID.
4. The agent calls `list_all_atlan_users` (filtering by email) to get Alex's newly created user ID.
5. The agent calls `atlan_users_add_to_groups` to bind Alex to the group.

**Output:** The LLM responds: *"Alex has been invited to Atlan as a member and added to the Data Engineering team group."*

### Scenario 2: SSO Mapping and Governance Audit
IT compliance requires ensuring that all external contractor groups in your IdP are properly mapped to restricted groups inside Atlan.

> "Audit our SSO mappings. Ensure the Okta group 'Vendors_2026' is mapped to the Atlan group 'external_contractors'. If the Atlan group doesn't exist, create it first."

1. The agent calls `atlan_groups_get_by_name` searching for "external_contractors".
2. If empty, it calls `create_a_atlan_group` passing the correct internal name and alias formatting.
3. The agent calls `list_all_atlan_sso_group_mappings` to view current IdP links.
4. Seeing the mapping is missing, the agent calls `create_a_atlan_sso_group_mapping` to link "Vendors_2026" to the Atlan group.

**Output:** The LLM responds: *"The 'external_contractors' group was missing, so I created it. I have successfully mapped the Okta 'Vendors_2026' group to this Atlan group for SSO access."*

### Scenario 3: Offboarding and Access Revocation
When a user changes departments or leaves, their specific group access within Atlan must be scrubbed.

> "Remove marcus@company.com from the 'finance_reporting' group."

1. The agent calls `list_all_atlan_users` with a filter to find Marcus's user GUID.
2. The agent calls `atlan_groups_get_by_name` to find the GUID for the "finance_reporting" group.
3. The agent calls `atlan_groups_remove_users` passing both GUIDs to revoke access.

**Output:** The LLM responds: *"Marcus has been successfully removed from the finance reporting group."*

## Building Multi-Step Workflows

To build this in code, you need to initialize your LLM, fetch the Atlan tools from Truto, and bind them to the model. This example uses the `@trutohq/truto-langchainjs-toolset` SDK, but the underlying `/tools` API works with any framework (LangGraph, CrewAI, Vercel AI SDK).

### Handling Rate Limits in Agent Loops

AI agents can execute tools much faster than humans, meaning they frequently hit third-party API rate limits. 

**Factual note on how Truto handles rate limits:** Truto does not automatically retry, throttle, or apply backoff when an upstream API returns a rate limit error. When Atlan returns an HTTP 429 (Too Many Requests), Truto passes that exact error back to your caller. To make handling this easier, Truto normalizes the upstream rate limit information into standardized HTTP headers per the IETF specification: `ratelimit-limit`, `ratelimit-remaining`, and `ratelimit-reset`. 

It is entirely your application's responsibility to read these headers and implement retry and backoff logic. Do not expect the integration layer to absorb 429s for you.

Here is how you structure the execution loop with LangChain, including a custom tool executor that respects Truto's normalized rate limit headers.

```typescript
import { ChatOpenAI } from "@langchain/openai";
import { TrutoToolManager } from "@trutohq/truto-langchainjs-toolset";
import { AgentExecutor, createToolCallingAgent } from "langchain/agents";
import { ChatPromptTemplate } from "@langchain/core/prompts";

// Helper to pause execution
const sleep = (ms: number) => new Promise(resolve => setTimeout(resolve, ms));

async function runAtlanAgent(integratedAccountId: string) {
  // 1. Initialize the LLM
  const llm = new ChatOpenAI({
    modelName: "gpt-4o",
    temperature: 0,
  });

  // 2. Fetch tools from Truto's /tools endpoint via the SDK
  const trutoManager = new TrutoToolManager({
    apiKey: process.env.TRUTO_API_KEY,
  });
  
  const tools = await trutoManager.getTools(integratedAccountId);

  // 3. Wrap tools to handle HTTP 429 errors based on Truto's normalized headers
  const rateLimitAwareTools = tools.map(tool => {
    const originalCall = tool.invoke.bind(tool);
    tool.invoke = async (input, config) => {
      let attempts = 0;
      const maxAttempts = 3;
      
      while (attempts < maxAttempts) {
        try {
          return await originalCall(input, config);
        } catch (error: any) {
          // Check if Truto passed down an HTTP 429
          if (error?.response?.status === 429) {
            // Read the standardized IETF rate limit headers provided by Truto
            const resetTimeHeader = error.response.headers.get('ratelimit-reset');
            
            if (resetTimeHeader) {
              const resetTimeMs = parseInt(resetTimeHeader, 10) * 1000;
              const waitTime = resetTimeMs - Date.now();
              
              if (waitTime > 0) {
                console.warn(`Rate limit hit. Sleeping for ${waitTime}ms...`);
                await sleep(waitTime + 100); // add slight buffer
                attempts++;
                continue;
              }
            }
            // Fallback exponential backoff if header is missing/unparseable
            const fallbackDelay = Math.pow(2, attempts) * 1000;
            console.warn(`Rate limit hit. Backing off for ${fallbackDelay}ms`);
            await sleep(fallbackDelay);
            attempts++;
            continue;
          }
          // Throw non-429 errors immediately
          throw error;
        }
      }
      throw new Error("Max rate limit retries exceeded.");
    };
    return tool;
  });

  // 4. Create the prompt and bind tools
  const prompt = ChatPromptTemplate.fromMessages([
    ["system", "You are an IT compliance assistant. You manage Atlan access."],
    ["human", "{input}"],
    ["placeholder", "{agent_scratchpad}"],
  ]);

  const agent = createToolCallingAgent({
    llm,
    tools: rateLimitAwareTools,
    prompt,
  });

  const executor = new AgentExecutor({
    agent,
    tools: rateLimitAwareTools,
  });

  // 5. Execute a multi-step workflow
  const result = await executor.invoke({
    input: "We have a new hire, alex@company.com. Invite them to Atlan as a $member, and add them to the 'data_engineering_team' group."
  });

  console.log(result.output);
}
```

### The Architecture Behind the Code

When this script runs, a fascinating sequence of events occurs between your agent, Truto, and Atlan.

```mermaid
sequenceDiagram
    participant Agent as Agent Framework
    participant Truto as Truto API
    participant Atlan as Atlan API
    
    Agent->>Truto: Call GET /integrated-account/<id>/tools
    Truto-->>Agent: Return JSON tool schemas for Atlan
    Agent->>Agent: LLM decides to call list_all_atlan_roles
    Agent->>Truto: Execute tool call (Proxy API)
    Truto->>Atlan: GET /api/service/roles
    Atlan-->>Truto: 200 OK (Role list)
    Truto-->>Agent: Return roles JSON
    Agent->>Agent: LLM extracts roleId for $member
    Agent->>Truto: Call create_a_atlan_user with roleId
    Truto->>Atlan: POST /api/service/users
    alt Rate Limit Hit
        Atlan-->>Truto: HTTP 429 Too Many Requests
        Truto-->>Agent: Pass 429 + ratelimit-* headers
        Agent->>Agent: Calculate backoff & retry
    else Success
        Atlan-->>Truto: 204 No Content
        Truto-->>Agent: Success response
    end
```

Notice that Truto sits entirely as a pass-through orchestration layer. It translates the raw OpenAPI-like definitions of the Atlan integration into JSON Schemas that LangChain understands, routes the execution, attaches the correct API credentials from the connected account, and returns the response. 

Crucially, Truto does not attempt to be clever with rate limiting. Because AI agents often rely on precise timing and state management, masking rate limit errors in the infrastructure layer can lead to stalled agent execution loops. By passing the `ratelimit-reset` header directly back to you, your code retains full control over how to pause and resume the agent's thought process.

## Moving Fast Without Breaking Things

Connecting Atlan to AI agents doesn't require a custom microservice for every data governance operation. By using a unified tools endpoint, you abstract away the Atlan-specific role resolution mechanics, string array wrappers, and strict path constraints, letting your LLM interact with a clean, hallucination-resistant schema.

Whether you are automating SSO group mappings, offboarding employees, or simply allowing users to query data dictionary access via natural language, the architecture remains the same. You connect the account, fetch the tools, implement your retry logic for rate limits, and let the agent do the heavy lifting.
