attendance-mcp

MCP server that exposes BIPO attendance tools to the BIPO AI assistant.

It is a thin, stateless proxy: each tool authenticates the caller (BIPO), then forwards the logged-in user's HRMS token to the existing BIPO HRMS / attendance API, which enforces all role permissions (Employee, Coordinator, Manager, HR).

• Language / framework: Python + FastMCP

• Transport: remote streamable-HTTP

• Auth:

  • Inbound (BIPO → server): x-service-key validated against MCP_SERVICE_KEY; the user's HRMS token arrives in X-HRMS-Authorization.

  • Outbound (server → HRMS API): the user's HRMS token forwarded as X-HRMS-Authorization.

Status: skeleton (pending HRMS API)

All 13 tools are wired and callable, but the real HRMS endpoints are not yet known. Every tool currently returns a structured PENDING_HRMS_API placeholder. Only src/attendance_mcp/bipo_client.py needs to change once the HRMS team provides the endpoints — replace each self._pending(...) with self._request(...).

See bipo-attendance-mcp-tools.html for the tool list shared with the HRMS team.

Tools

Scenario 5 guardrail: OT requests cannot be deleted — only cancelled. There is intentionally no delete_ot_request tool.

Setup

python -m venv .venv
.venv\Scripts\activate        # Windows
pip install -e ".[dev]"
cp .env.example .env          # then edit BIPO_API_BASE_URL etc.

Run

attendance-mcp                # streamable-HTTP on MCP_HOST:MCP_PORT (default 127.0.0.1:8000)

Test

pytest
