# Connect Humaans to Claude: Sync Payroll, Performance, and Leave
If you need to connect Humaans to Claude to automate HR operations, track employee time away, or orchestrate performance review cycles, 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 natural language tool calls and the Humaans REST API. You can either build and maintain this infrastructure yourself (or follow our [guide to building MCP servers](https://truto.one/the-hands-on-guide-to-building-mcp-servers-for-ai-agents-2026/)), or use a [managed integration platform like Truto](https://truto.one/best-mcp-server-platforms-for-enterprise-ai-agents-2026/) to dynamically generate a secure, authenticated MCP server URL.
If your team uses ChatGPT, check out our guide on [connecting Humaans to ChatGPT](https://truto.one/connect-humaans-to-chatgpt-automate-hr-operations-and-records/) or explore our broader architectural overview on [connecting Humaans to AI Agents](https://truto.one/connect-humaans-to-ai-agents-automate-lifecycles-and-timesheets/).
Giving a Large Language Model (LLM) read and write access to a specialized Human Resources Information System (HRIS) like Humaans is an engineering challenge. You must handle authentication token lifecycles, map massive JSON schemas to MCP tool definitions, and deal with highly relational HR data models. Every time Humaans updates an endpoint or deprecates a field, you have to update your server code, redeploy, and test the integration.
This guide breaks down exactly how to use Truto to generate a secure, managed MCP server for Humaans, connect it natively to Claude, and execute complex HR management workflows using natural language.

## The Engineering Reality of the Humaans 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 a highly specialized B2B API like Humaans is painful. Humaans is built to manage complex organizational hierarchies, multi-region compliance, and deep employee lifecycle records. Its API reflects that domain complexity.
If you decide to build a custom Humaans MCP server, here are the specific integration challenges you will face:
**Temporal Data Structures**
In Humaans, records like job roles, working patterns, and compensations are not static fields on a user profile. They are temporal records that exist on a timeline, governed by `effective_date` parameters. Querying "What is John's current salary?" requires the LLM to understand how to fetch a list of compensation objects, filter by the current date, and interpret the active record. When writing data - like promoting an employee - you cannot simply send an update payload to a static `job_title` field. You must create a new temporal job role record with a future effective date. A managed MCP server exposes these exact schema requirements to the LLM, preventing malformed write requests.
**Highly Relational Time-Away Logic**
Calculating and requesting time away in Humaans involves a web of dependencies. An LLM cannot just deduct integers from a balance. A time away request intersects with `working_pattern_allocations` (to know what days the employee actually works), `public_holiday_calendars` (to avoid deducting statutory holidays), and `time_away_policies` (which dictate accrual rules). Truto's dynamic tool generation ensures that the query and body schemas for these endpoints explicitly guide the LLM to fetch the necessary dependent resources before executing a state change.
**Strict Rate Limits and Pagination**
Humaans enforces strict API rate limits to protect its infrastructure. It is critical to understand that Truto does not automatically retry, throttle, or apply backoff on rate limit errors. When the Humaans API returns an HTTP 429 status code, Truto passes that exact error back to the caller. However, Truto normalizes the upstream rate limit information into standardized headers (`ratelimit-limit`, `ratelimit-remaining`, `ratelimit-reset`) per the IETF specification. The caller - in this case, the AI agent framework or Claude client - is responsible for implementing the retry and backoff logic. Furthermore, Humaans uses specific `$limit` and `$skip` parameters for pagination. Truto automatically injects `limit` and `next_cursor` instructions into the tool descriptions, explicitly instructing the LLM to handle pagination correctly across large employee directories.
## Creating the Humaans MCP Server
Truto derives MCP tools dynamically from the underlying Humaans integration resources and documentation. A tool only appears in the MCP server if it has a corresponding documentation entry, ensuring that Claude only sees well-curated, AI-ready endpoints.
You can create an MCP server for Humaans using either the Truto UI or the API.
### Method 1: Via the Truto UI
1. Navigate to the **Integrated Accounts** page in your Truto dashboard.
2. Select your connected Humaans account.
3. Click the **MCP Servers** tab.
4. Click **Create MCP Server**.
5. Select your desired configuration (e.g., restrict to `read` methods only, or filter by specific tags like `hr`).
6. Copy the generated MCP server URL (e.g., `https://api.truto.one/mcp/a1b2c3...`).
### Method 2: Via the Truto API
For teams automating their infrastructure, you can generate an MCP server programmatically. This endpoint creates a secure token, stores it, and returns the ready-to-use URL.
```typescript
// POST https://api.truto.one/integrated-account/{integrated_account_id}/mcp
// Headers: Authorization: Bearer {TRUTO_API_KEY}
{
"name": "Claude Humaans Access",
"config": {
"methods": ["read", "write"],
"tags": ["people", "time_away"]
},
"expires_at": "2026-12-31T23:59:59Z"
}
```
The API responds with the server ID and the cryptographic token URL:
```json
{
"id": "mcp_srv_987654321",
"name": "Claude Humaans Access",
"url": "https://api.truto.one/mcp/abc123def456..."
}
```
## Connecting the MCP Server to Claude
Once you have your Humaans MCP server URL, you must configure your Claude client to use it as a remote tool server over Server-Sent Events (SSE).
### Method A: Via the Claude UI (Desktop/Web)
If you are using Claude's interface (or ChatGPT's custom connectors):
1. In Claude, navigate to **Settings** -> **Integrations** -> **Add MCP Server** (Note: Exact menu paths vary by plan tier).
2. Paste your Truto MCP URL.
3. Click **Add**. Claude will immediately perform a handshake, discover the Humaans tools, and register their schemas.
### Method B: Via the Claude Desktop Config File
For local development and engineering teams using Claude Desktop, you can configure the MCP server manually using the JSON config file. This requires using the `@modelcontextprotocol/server-sse` package to proxy the connection.
Locate your `claude_desktop_config.json` file (typically in `~/Library/Application Support/Claude/` on macOS or `%APPDATA%\Claude\` on Windows) and add the following configuration:
```json
{
"mcpServers": {
"humaans-truto": {
"command": "npx",
"args": [
"-y",
"@modelcontextprotocol/server-sse",
"https://api.truto.one/mcp/abc123def456..."
]
}
}
}
```
Restart Claude Desktop. The model will automatically read the available Humaans resources and load them into its context.
## Humaans AI Hero Tools
Truto exposes the entirety of the Humaans API as MCP tools. By mapping the integration's query and body schemas into a flat input namespace, Claude knows exactly what arguments to provide. Here are the highest-leverage tools for automating HR operations.
### list_all_humaans_people
This is the central entry point for almost all Humaans workflows. It retrieves the employee directory, allowing Claude to filter by status, email, or department to locate the correct Humaans ID required for subsequent operations.
> "Find the Humaans ID for the employee with the email address j.doe@example.com and check if their profile status is currently active."
### list_all_humaans_time_away
Retrieves time away entries for personnel, including per-day breakdowns and approval statuses. This tool is vital for auditing team availability, calculating leave balances, and syncing out-of-office schedules.
> "Fetch all approved time away entries for the engineering team next month. Ignore declined or pending requests."
### create_a_humaans_time_away
Allows the agent to submit a new time away request on behalf of an employee. The schema requires the model to correctly pass the employee ID, the time away type ID (e.g., PTO, sick leave), and the start/end dates.
> "Log a sick leave request for Sarah Jenkins starting today and ending tomorrow. Ensure the time away type is set to 'Sick Leave'."
### list_all_humaans_compensations
Retrieves the compensation history for employees. Because compensations in Humaans are temporal, this tool allows the LLM to audit salary bands, review upcoming compensation changes, or extract historical payroll data.
> "Pull the current active compensation record for the Senior DevOps Engineer role to verify they are in the correct salary band."
### update_a_humaans_job_role_by_id
Updates an existing job role. This tool is used for promotions, department transfers, or correcting reporting lines. The LLM understands from the schema that it only needs to supply the specific fields being altered.
> "Update Marcus's job role record to reflect his promotion to 'Lead Designer' and change his reporting line manager to the VP of Product."
### list_all_humaans_performance_cycle_reviews
Fetches individual reviews within a specific performance cycle. This allows AI agents to aggregate performance data, summarize review feedback, and orchestrate automated follow-ups for HR business partners.
> "Retrieve all submitted performance reviews for the Q3 Engineering cycle and identify any employees who received a 'Needs Improvement' rating."
To view the complete schema definitions and the full list of available operations, visit the [Humaans integration page](https://truto.one/integrations/detail/humaans).
## Workflows in Action
Once Claude has access to the Humaans MCP server, it can orchestrate complex, multi-step HR workflows autonomously. Here are two concrete examples of how an AI agent navigates the Humaans API.
### Workflow 1: Executing a Department Reorganization
When a company shifts its organizational structure, updating reporting lines manually is tedious. An HR administrator can prompt Claude to handle the bulk updates.
> "We are moving the 'Cloud Infrastructure' team under the 'Platform Engineering' org unit. Find all employees currently in Cloud Infrastructure, update their job roles to map to the new org unit ID, and set their new manager to Elena Rostova."
```mermaid
sequenceDiagram
participant User as HR Admin
participant Claude as Claude Desktop
participant Truto as Truto MCP Server
participant Humaans as Humaans API
User->>Claude: "Move Cloud Infra to Platform Eng under Elena..."
Claude->>Truto: Call list_all_humaans_org_units (query: "Cloud Infrastructure")
Truto->>Humaans: GET /org-units?name=Cloud+Infrastructure
Humaans-->>Truto: Return org unit ID
Truto-->>Claude: Return org unit data
Claude->>Truto: Call list_all_humaans_people (query: name="Elena Rostova")
Truto->>Humaans: GET /people?email=elena...
Humaans-->>Truto: Return manager ID
Truto-->>Claude: Return person data
Claude->>Truto: Call list_all_humaans_job_roles (query by old org unit)
Truto->>Humaans: GET /job-roles?org_unit_id=...
Humaans-->>Truto: Return list of job roles
Truto-->>Claude: Return job roles
loop For each job role
Claude->>Truto: Call update_a_humaans_job_role_by_id
Truto->>Humaans: PATCH /job-roles/{id}
Payload: new org_unit_id, manager_id
Humaans-->>Truto: 200 OK
Truto-->>Claude: Update successful
end
Claude-->>User: "Successfully moved 14 employees to Platform Engineering..."
```
**What the user gets back:** Claude replies with a confirmation summary, listing exactly which employees were updated, the new organizational unit ID applied, and verification that the reporting line was successfully changed to the new manager.
### Workflow 2: Time Away Audit and Conflict Resolution
A project manager needs to ensure they have enough coverage during the holidays.
> "Check the time away records for all frontend engineers in December. If more than two engineers are approved for overlapping PTO, generate a list of the conflicting dates and the personnel involved."
```mermaid
flowchart TD
A["Call list_all_humaans_org_units
Find 'Frontend Engineering'"] --> B["Call list_all_humaans_people
Filter by org unit ID"]
B --> C["Call list_all_humaans_time_away
Filter by employee IDs & Dec dates"]
C --> D["Claude evaluates overlapping
date ranges locally"]
D --> E["Format conflict report
Return to User"]
```
**What the user gets back:** Claude processes the temporal data from the time away entries, identifies overlaps using its own reasoning capabilities, and outputs a formatted list of days where staffing coverage drops below the required threshold, complete with the names of the engineers on leave.
## Security and Access Control
Giving an AI model access to sensitive HR and payroll data requires strict governance. Truto provides granular access controls baked directly into the MCP token layer:
* **Method Filtering:** Restrict the MCP server to specific HTTP methods. By setting `config.methods: ["read"]`, you guarantee the LLM can only query data (like viewing org charts) and cannot modify records (like changing salaries or deleting personnel).
* **Tag Filtering:** Group Humaans endpoints by business function using `config.tags`. You can create an MCP server that only exposes `time_away` tags, completely blinding the LLM to `compensation` or `bank_accounts` endpoints.
* **Extra Authentication (`require_api_token_auth`):** For zero-trust environments, enable `require_api_token_auth: true`. The MCP client must then pass a valid Truto API session token in the authorization header, ensuring that simply possessing the MCP URL is not enough to execute tools.
* **Automatic Expiration (`expires_at`):** Generate short-lived MCP servers for contractors or temporary AI audits by setting an ISO datetime expiration. Truto's durable objects will automatically delete the server and revoke access at the specified time.
## Build Faster HR Automations
Connecting Humaans to Claude transforms static HR data into an interactive, agentic workflow. Rather than forcing your team to navigate complex HRIS UI dashboards to pull reports, audit org structures, or process leave requests, you can empower AI agents to execute these tasks deterministically via the Humaans API.
Building a custom integration layer to handle Humaans's temporal data models, deep pagination, and strict rate limits is an unnecessary engineering burden. By utilizing Truto's documentation-driven MCP architecture, you instantly inherit a flat, schema-validated toolset that LLMs inherently understand. Your engineers stop writing boilerplate integration code, and your operations teams get immediate access to powerful AI-driven HR workflows.
