tia-portal-mcp

tia-portal-mcp is a skill for Claude Code from Czarnak/totally-integrated-claude. It costs 37 tokens per session (1,386 once invoked), scanned A, original, MIT.

A guarded interface for reading and making limited changes in Siemens TIA Portal projects through an MCP server, a tool connection that lets an agent call defined project operations.

In plain words
What is it for?
Use it to browse project trees, inspect blocks and hardware, list tags, check compilation, read cross-references, search equipment, and preview or apply supported writes.
Why use it?
It provides a small, explicit set of project actions and requires write previews before applying changes, helping reduce accidental edits.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

tia-portal-mcp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 13d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Scope

Use this skill for direct TIA Portal interaction through the MCP server. The server exposes exactly ten public MCP tools: three batch tools and seven project lifecycle tools. Internal worker operations, including lifecycle probes, are not MCP-visible tools.

Use MCP for exploration, inspection, and bounded changes. For loops, bulk automation, or an operation outside this surface, use tia-openness-roadmap.

Public tool surface

Data operations

Tool Purpose
execute_read_batch Run up to 50 independent read operations.
preview_write_batch Preview up to 50 data-write operations and obtain one batch safety token.
apply_write_batch Apply the exact previewed write batch sequentially; stop on the first failure and mark remaining items skipped. There is no transaction or rollback.

Read-operation names include browse_project_tree, get_block_content, list_tag_tables, read_hardware_config, read_cross_references, search_equipment_catalog, compile_check, and get_project_status. Data-write operation names include block, tag-table, tag, user-constant, and network-device operations such as update_block_logic, create_block, create_tag, and add_network_device.

Project lifecycle

Tool Purpose
get_project_status Inspect the currently open project.
open_project Deliberately open or switch to a project.
create_project Create a project.
save_project Save the open project.
save_project_as Copy the open project and rebind to the copy.
archive_project Create an archive of the open project.
close_project Close the open project.

get_project_status(projectPath) is read-only and non-binding. It never opens or switches a project, including when projectPath names a different project. Use open_project for deliberate session switching. If a bound session names a different path in a status request, the result is binding_conflict; do not use status as a switching mechanism.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
