power-ops-mcp
Provides structured tools for thermal power operations, including defect and work order search, summaries, and failure analysis. Replaces free SQL with fixed templates and supports dashboard and service status.
README
火电运维问数 MCP
该服务把生产工作流里的自由 SQL 查询替换为 8 个核心工具、2 个业务扩展工具和固定支持工具。Apache Ossie 模型是字段、维度、指标、状态和工具目录的唯一语义源;MCP 只消费经过验证的生成注册表。所有查询均为固定模板和参数化 SQL,不暴露 sql、where_sql、order_by_sql 等自由输入。

工具
核心工具:
search_equipmentsearch_defectsget_defect_detailsummarize_defectssearch_workordersget_workorder_detailsummarize_workordersanalyze_workorder_failures
扩展工具:analyze_workorder_materials、get_equipment_operation_summary。
此外提供 get_maintenance_dashboard 和 get_service_status 支持工具。前者负责能力导航、数据概况、数据时间边界和澄清消息;后者返回版本、语义指纹和可选数据库就绪状态。业务查询工具仍保持 8+2 的设计。
本地虚拟环境
uv sync --extra test
uv run pytest
uv run python app.py
修改 semantic/power_operations.ossie.yaml 后必须重新编译:
uv run python scripts/compile_semantics.py
uv run python scripts/compile_semantics.py --check
不要直接编辑 generated/ 下的文件。
本项目统一使用 uv 管理 .venv 和 uv.lock,不要直接运行 pip install 或 python -m venv。
容器启动
先按 database/README.md 部署版本化视图,再复制 .env.example 为 .env,填写只读 MySQL 账号和随机 MCP Token。该账号应只拥有 mcp_schema_version 及以下视图的 SELECT 权限:
vw_qa_defectvw_qa_defect_factvw_qa_work_ordervw_qa_work_order_fact
然后运行:
docker compose -f compose.example.yml up --build
默认使用带 Bearer Token、Host/Origin 防护的 Streamable HTTP。Dify 中应配置 <domain>_mcp_auth_token,让意图识别节点输出 tool_name + arguments,不再输出 SQL。
运行端点:
/health/live:进程存活。/health/ready:数据库、Schema 版本及视图字段契约。/metrics:Prometheus 文本指标。
查询层使用有界连接池、并发信号量和 MySQL MAX_EXECUTION_TIME;容量耗尽时快速失败,不创建无限排队。
数据边界
- 缺陷按
defect_code去重,且没有可靠时间字段。 - 工单按
workorder_code去重;只有计划开始、计划完成时间,没有实际完成时间。 - “超期”仅指计划完成时间早于查询基准时间,且状态不是已关闭、已取消、已作废。
- 单次明细或汇总返回上限为 50。
- 日志只记录工具名、参数数量、耗时和返回条数,不记录密码或结果数据。
