# mcp_servers/
MCP (Model Context Protocol) servers wrapping the four AssetOpsBench tool domains. Each subdirectory is a standalone MCP server that can be launched independently or composed into a multi-server agent pipeline.
## Architecture
All four servers import shared data-loading helpers from `base.py`, which points at `data/processed/`. Each server exposes a set of tools via the MCP JSON-RPC interface.
```
mcp_servers/
├── base.py # shared data loader + utilities
├── iot_server/ # asset metadata + sensor readings
│ └── server.py # tools: list_assets, get_asset_metadata, list_sensors, get_sensor_readings
├── fmsr_server/ # failure mode to sensor relation
│ └── server.py # tools: list_failure_modes, search_failure_modes, get_sensor_correlation,
│ # get_dga_record, analyze_dga (IEC 60599 Rogers Ratio)
├── tsfm_server/ # time-series forecasting + RUL
│ └── server.py # tools: get_rul, forecast_rul, detect_anomalies (z-score),
│ # trend_analysis (OLS)
└── wo_server/ # work order management
└── server.py # tools: list/get fault records, create/list/update work orders,
# estimate_downtime
```
## Running a server
```bash
# From repo root, with the team .venv active:
python -m mcp_servers.iot_server.server
```
In practice, the benchmark path composes multiple servers at once; these modules are intentionally independent so the harness can start only the domains it needs. The agent or harness layer, not the server, is responsible for multi-turn orchestration across domains.
## Design notes
- **Shared loader layer** keeps data loading DRY — schema changes in `data/processed/` only need updating in `base.py`.
- **Stateless tool calls** — servers don't maintain session state; the agent holds multi-turn context.
- **No network side effects** — all read paths come from local CSVs. The only write path is the in-memory WO session store used for work-order creation during a run.
- **Real domain logic, not stubs** — e.g. `fmsr_server.analyze_dga` implements the IEC 60599 Rogers Ratio method for dissolved gas analysis, not a dummy return.
## Status (Apr 7, 2026)
- **Skeletons landed** for all four domains (commit `717e9b4`, Anonymous reviewer)
- **Substantive domain logic** implemented (Rogers Ratio, RUL forecast, anomaly detection, work-order CRUD)
- **In progress (W2):** hardening, unit tests, integration with the AssetOpsBench evaluation harness
