Tia Commander MCP Server

New in this release: a new technology_objects tool - 15 actions for listing and reading technology objects, changing parameters, structural edits, export/import, and connecting an object to its hardware; per-project PLC credentials with a new Credentials tab in the Manager - a project's own password is tried first, a global one is the fallback; transactional block overwrites - the block is exported before the import…. Its 11 documented tools cluster into blocks, admin, alarm, other.

People who work with dotnet, factory automation and plc and want it reachable from Claude, Cursor, VS Code, or another MCP client.
