tia-portal-mcp MCP server for Siemens SIMATIC TIA Portal V21. It lets MCP clients and AI agents inspect a running TIA Portal project through the Siemens Openness API. The current implementation covers project discovery and lifecycle operations, PLC block export/import, tag table reads and guarded tag mutations, hardware/network discovery, cross-reference diagnostics, hardware catalog search, guarded network-device provisioning, and compile/check diagnostics. Tools The server currently exposes 16 tools. Batch operations - run up to 50 read operations in one call. Each item carries an , an name (e.g. , ), and that operation's parameters. Reads run independently, so a failing item does not stop the others. / - preview up to 50 write operations and receive one batch-level bound to the exact ordered operation list and the combined current state, then apply them. Apply runs sequentially, stops on the first failure, and marks later items (no transaction or rollback). Requires and the . Batches cover data writes (block, tag table, tag, user constant, network device); project-lifecycle operations stay single-tool only. The batch tools are the only path for data operations. Each name (e.g.

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy, covering 11 red-flag categories including credential harvesting, data exfiltration, and curl | sh installers. It is a first-layer scan, not a manual audit — we say so rather than overstate it.
The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
