# Connect Microsoft Sentinel to Claude: Hunt Threats & Manage Intel


If you need to connect Microsoft Sentinel to Claude to automate threat hunting, triage security incidents, analyze alerts, or execute remediation playbooks, you need a [Model Context Protocol (MCP) server](https://truto.one/what-is-mcp-and-mcp-servers-and-how-do-they-work/). This server acts as the translation layer between Claude's AI tool calls and Microsoft Sentinel's underlying REST APIs. You can either build, host, and maintain this infrastructure yourself, or use a [managed integration platform](https://truto.one/managed-mcp-for-claude-full-saas-api-access-without-security-headaches/) like Truto to dynamically generate a [secure, authenticated MCP server URL](https://truto.one/managed-mcp-for-claude-full-saas-api-access-without-security-headaches/). If your security operations team [uses ChatGPT](https://truto.one/connect-microsoft-sentinel-to-chatgpt-manage-incidents-alerts/), check out our guide on [/connect-microsoft-sentinel-to-chatgpt-manage-incidents-alerts/](https://truto.one/connect-microsoft-sentinel-to-chatgpt-manage-incidents-alerts/) or explore our [broader architectural overview](https://truto.one/connect-microsoft-sentinel-to-ai-agents-automate-security-ops/) on [/connect-microsoft-sentinel-to-ai-agents-automate-security-ops/](https://truto.one/connect-microsoft-sentinel-to-ai-agents-automate-security-ops/).

Giving a Large Language Model (LLM) read and write access to a cloud-native SIEM like Microsoft Sentinel is an engineering challenge. You are not just dealing with simple CRUD operations; you have to handle complex Azure Resource Manager (ARM) taxonomies, strict concurrency controls, and massive nested JSON schemas for security alerts. Every time Microsoft updates an endpoint or deprecates a legacy Log Analytics workspace feature, you have to update your custom server code, redeploy, and test the integration.

This guide breaks down exactly how to use Truto to generate a secure, managed MCP server for Microsoft Sentinel, connect it natively to Claude, and execute complex security workflows using natural language.

## The Engineering Reality of the Microsoft Sentinel API

A custom MCP server is a self-hosted integration layer. While the open MCP standard provides a predictable way for models to discover tools, the reality of implementing it against Microsoft Sentinel's APIs is painful. Sentinel is deeply embedded in the Azure ecosystem, meaning its API inherits all the complexity of enterprise cloud governance.

If you decide to build a custom MCP server for Microsoft Sentinel in-house, here are the specific integration challenges you will face:

**The Azure Resource Manager (ARM) Hierarchy**
Microsoft Sentinel does not operate in a vacuum. It sits on top of a Log Analytics workspace, which belongs to a Resource Group, which belongs to an Azure Subscription. Almost every API call requires you to pass the `workspace_name` and often implies a complex routing path like `/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/...`. An LLM has no inherent context of your Azure topology. A well-designed MCP implementation must abstract this routing or expose tools that allow the LLM to recursively discover the subscription, the resource group, and the target workspace before executing a query.

**Strict Concurrency via ETags**
Security operations are highly concurrent. Multiple analysts, automation rules, and logic apps might be modifying the same incident simultaneously. To prevent lost updates, Microsoft Sentinel heavily enforces optimistic concurrency using `ETag` headers. When you want Claude to update an incident (e.g., changing its status to closed or modifying its severity), the LLM cannot simply fire a PATCH request. It must first retrieve the incident, extract the `etag` property, and pass that exact string back in the update payload. If the ETag is missing or stale, the API rejects the write. You must explicitly design your MCP tool schemas to require ETag passthrough.

**Asynchronous State and HTTP 202 Responses**
Many operations in Sentinel are asynchronous. For instance, when deleting a large watchlist or purging specific incident data, the API will not return a simple HTTP 200 OK. Instead, it returns an HTTP 202 Accepted, along with an `Azure-AsyncOperation` header containing a URL to track the job's status. Standard LLM tool execution expects synchronous confirmation. Your custom MCP server must implement polling logic to wrap these async tasks, holding the connection open until the Azure backend confirms success, otherwise the LLM will hallucinate that a long-running operation completed instantly.

## Generating the Microsoft Sentinel MCP Server

Rather than dealing with Azure token refreshes, ETag extraction, and ARM path resolution in custom code, you can use Truto to dynamically generate a complete MCP server. This server translates Sentinel's raw endpoints into curated, schema-validated tools.

Truto creates these tools dynamically from API documentation records and resource configurations. Tools are not hardcoded; they are generated on the fly when the MCP client connects. You can create an MCP server via the Truto UI or via the API.

### Method 1: Via the Truto UI

For teams who prefer visual configuration, you can deploy a server in seconds:

1. Log into Truto and navigate to the **Integrated Accounts** page.
2. Select your connected Microsoft Sentinel account.
3. Click the **MCP Servers** tab.
4. Click **Create MCP Server**.
5. Select your desired configuration (e.g., read-only access, specific tag filters, or setting an expiration date).
6. Copy the generated MCP server URL. Keep this secure, as it contains the cryptographic token required for access.

### Method 2: Via the Truto API

For platform engineering teams automating agent deployment, you can generate MCP servers programmatically. This is ideal for provisioning temporary, scoped access for ephemeral AI agents.

Make a POST request to `/integrated-account/:id/mcp` using your Truto API key:

```bash
curl -X POST https://api.truto.one/integrated-account/<your_sentinel_account_id>/mcp \
  -H "Authorization: Bearer <your_truto_api_token>" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Claude SOC Analyst Assistant",
    "config": {
      "methods": ["read", "write"],
      "tags": ["incidents", "threat_intel"]
    },
    "expires_at": "2026-12-31T23:59:59Z"
  }'
```

The Truto API will evaluate the integration, verify available tools, and return a secure endpoint:

```json
{
  "id": "mcp_8a9b0c1d",
  "name": "Claude SOC Analyst Assistant",
  "config": {
    "methods": ["read", "write"],
    "tags": ["incidents", "threat_intel"]
  },
  "expires_at": "2026-12-31T23:59:59Z",
  "url": "https://api.truto.one/mcp/sec_778899aabbccddeeff"
}
```

This URL is the only configuration your client needs to discover and execute Microsoft Sentinel tools.

## Connecting the MCP Server to Claude

Once you have your MCP server URL, connecting it to Claude is a straightforward process. You can configure this via the Claude interface or manually via a configuration file.

### Method A: Via the Claude UI (If supported by your client version)

If you are using an enterprise AI client with a visual connector setup (similar to ChatGPT's custom connectors):

1. Open your client settings and locate the **Connectors** or **Integrations** panel.
2. Click **Add Custom Connector** or **Add MCP Server**.
3. Name the connector (e.g., "Microsoft Sentinel SOC").
4. Paste the Truto MCP server URL generated in the previous step.
5. Click **Add**. The client will automatically handshake with the URL, exchange the JSON-RPC 2.0 initialization messages, and list the available Sentinel tools.

### Method B: Via Manual Config File (Claude Desktop)

For developers using the standard Claude Desktop application, you can configure the MCP server by editing your `claude_desktop_config.json` file. Truto's MCP servers communicate over HTTP, so you use the Server-Sent Events (SSE) transport provided by the official MCP SDK.

Open your configuration file and add the Sentinel server:

```json
{
  "mcpServers": {
    "microsoft_sentinel": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-sse",
        "https://api.truto.one/mcp/sec_778899aabbccddeeff"
      ]
    }
  }
}
```

Restart Claude Desktop. When you open a new chat, Claude will automatically fetch the Microsoft Sentinel tool schemas and make them available for natural language invocation.

## Microsoft Sentinel Hero Tools for Claude

Truto maps the complex Microsoft Sentinel API into a comprehensive suite of AI tools. Rather than exposing raw REST endpoints, Truto normalizes the inputs and outputs, ensuring Claude knows exactly what query parameters and body schemas are required. Here are the highest-leverage tools available for security operations.

### 1. List All Incidents
**Tool name:** `list_all_microsoft_sentinel_incidents`

This tool retrieves all active security incidents within a specified Log Analytics workspace. Claude can use this to provide a morning briefing for a SOC analyst or filter for unassigned, high-severity alerts. It automatically handles the `nextLink` cursor for pagination.

> "Fetch all new high-severity incidents from the 'SecOps-Prod' workspace that were created in the last 24 hours and have not yet been assigned to an analyst."

### 2. Get Incident Alerts
**Tool name:** `list_all_microsoft_sentinel_incident_alerts`

An incident in Sentinel is a container for multiple correlated alerts. This tool fetches the specific underlying alerts tied to an incident, allowing Claude to inspect the raw security signals, attack vectors, and triggering logic that caused the incident to fire.

> "Get the detailed alerts associated with incident ID 'inc-4459' in the 'SecOps-Prod' workspace. Summarize the specific malware signatures or behavioral anomalies detected."

### 3. Query Threat Intelligence Indicators
**Tool name:** `list_all_microsoft_sentinel_main_indicators`

Threat intelligence is useless if it is hard to query. This tool allows Claude to search the workspace's threat intel database to see if a specific IP address, file hash, or domain is a known malicious indicator. It returns the indicator's confidence score and threat type.

> "Check our threat intelligence indicators in the 'SecOps-Prod' workspace for the IP address '198.51.100.42'. Tell me if it is associated with any known botnets or phishing campaigns."

### 4. Execute an Automation Playbook
**Tool name:** `create_a_microsoft_sentinel_incident_run_playbook`

This is a critical write operation. It allows Claude to trigger a specific Logic App playbook against a target incident. When an analyst tells Claude to isolate a host or block a user in Azure AD, Claude uses this tool to initiate the automated response.

> "Run the 'Block-AzureAD-User' playbook against incident 'inc-4459' in the 'SecOps-Prod' workspace. The logic app resource ID is '/subscriptions/sub1/resourceGroups/rg1/providers/Microsoft.Logic/workflows/block-user'."

### 5. Update an Incident Comment
**Tool name:** `update_a_microsoft_sentinel_incident_comment_by_id`

Documentation is a massive time sink for SOC analysts. This tool allows Claude to document its findings directly into the Sentinel incident timeline. After investigating an alert, Claude can upsert a detailed summary, tagging it with relevant MITRE ATT&CK tactics.

> "Add a comment to incident 'inc-4459' stating that the underlying alerts indicate a false positive caused by a scheduled vulnerability scan, and include the ETag 'W/\"datetime\'2026-10-15\'\"'."

## Workflows in Action

Connecting Microsoft Sentinel to Claude transforms static API endpoints into dynamic, multi-step [agentic workflows](https://truto.one/connect-microsoft-sentinel-to-ai-agents-automate-security-ops/). By chaining tools together, Claude can execute complex security investigations autonomously.

### Scenario 1: Automated Incident Triage and Enrichment

SOC analysts spend hours manually reviewing low-level alerts to determine if they warrant escalation. Claude can automate this initial triage by fetching the incident, reading the alerts, querying threat intelligence, and updating the incident with a summary.

> "Review the newest unassigned critical incident in the SecOps-Prod workspace. Check its alerts, extract any IP addresses, verify them against our threat intel indicators, and leave a comment with your findings."

    MCP->>Sentinel: GET /incidents?filter=severity eq 'High'
    Sentinel-->>MCP: Returns incident "inc-992"
    MCP-->>Claude: JSON incident data
    Claude->>MCP: Call list_all_microsoft_sentinel_incident_alerts
    MCP->>Sentinel: POST /incidents/inc-992/alerts
    Sentinel-->>MCP: Returns alert payloads with IPs
    MCP-->>Claude: JSON alert data
    Claude->>MCP: Call list_all_microsoft_sentinel_main_indicators
    MCP->>Sentinel: GET /threatIntelligence/indicators (filter by IP)
    Sentinel-->>MCP: Returns malicious indicator match
    MCP-->>Claude: Threat intel context
    Claude->>MCP: Call update_a_microsoft_sentinel_incident_comment_by_id
    MCP->>Sentinel: PUT /incidents/inc-992/comments/c1
    Sentinel-->>MCP: 200 OK
    MCP-->>Claude: Success confirmation
    Claude->>User: Incident triaged. Comment added confirming malicious IP.
```

### Scenario 2: Threat Hunting and Automated Remediation

When a specific IOC (Indicator of Compromise) is detected in the wild, you need to quickly determine if it has impacted your environment and take action. Claude can hunt for the entity and immediately trigger a remediation playbook.

> "Check if any incidents in the SecOps-Prod workspace involve the user 'admin_jsmith'. If you find an active incident, trigger the 'Force-Password-Reset' playbook and close the incident."

## Security and Access Control

Exposing a critical security system like Microsoft Sentinel to an LLM requires strict governance. Truto's MCP architecture provides multiple layers of access control, ensuring your agent only has the permissions it absolutely needs.

*   **Documentation-Driven Tool Generation:** Truto dynamically generates tools based on explicit integration definitions. If an endpoint is undocumented or marked internal, it will not be generated as a tool. This acts as a quality gate, preventing the LLM from hallucinating unauthorized API calls.
*   **Method and Tag Filtering:** When you generate the MCP server URL via `POST /integrated-account/:id/mcp`, you can apply strict filters. Setting `methods: ["read"]` ensures Claude can only list incidents and alerts, entirely disabling destructive write actions. You can also filter by `tags: ["threat_intel"]` to restrict the server to specific operational domains.
*   **Dual-Layer Authentication:** By default, possessing the MCP URL is enough to access the server. For zero-trust environments, you can enable `require_api_token_auth: true`. This forces the MCP client to pass a valid Truto API token in the Authorization header, ensuring the caller is an authenticated team member.
*   **Automated Server Expiration:** For temporary investigations or contractor access, you can set the `expires_at` parameter. Truto utilizes edge-based key-value expiration and scheduled cleanup alarms to guarantee the MCP server self-destructs at the exact specified time.
*   **Rate Limit Handling:** Truto does not retry, throttle, or apply automatic backoff on rate limit errors. If Microsoft Sentinel returns an HTTP 429 Too Many Requests, Truto passes that error directly to the caller, normalizing the upstream data into standardized IETF headers (`ratelimit-limit`, `ratelimit-remaining`, `ratelimit-reset`). The caller (Claude or your agent framework) is responsible for implementing retry and backoff logic.

## Final Thoughts

Connecting Microsoft Sentinel to Claude transforms how security operations centers function. By deploying an MCP server, you eliminate the massive overhead of mapping Azure ARM resources, handling strict ETags, and maintaining OAuth lifecycles. Instead, your engineering team can focus on writing better agentic playbooks while Claude handles the heavy lifting of data triage, threat correlation, and [automated incident response](https://truto.one/connect-microsoft-sentinel-to-ai-agents-automate-security-ops/).

With managed MCP infrastructure, AI agents stop being theoretical concepts and become active, auditable members of your SOC team.
