What is configure-stm32cubemx?

A workflow for creating, inspecting, planning, validating, and generating STM32CubeMX and STM32CubeIDE projects. STM32CubeMX configures STM32 microcontrollers, which are small computers used in embedded devices.

Use it to create or update STM32 IOC configuration files, assign pins, enable hardware peripherals, validate settings, and generate CubeIDE projects.

It organizes hardware settings such as pins, peripherals, clocks, and project options while requiring review before applying changes.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00090	$0.00859
Opus 5.5	$0.00036	$0.00344
Sonnet 5.5	$0.00018	$0.00172
Haiku 4.5	$0.00009	$0.00086

Security

Grade A, and why

configure-stm32cubemx 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Configure STM32CubeMX

Use the MCP as the deterministic execution layer. Analyze datasheets, schematics, images, and user requirements in the host agent before you create a structured tool call.

Workflow

Call cubemx_environment. Confirm that CubeMX is available. Review the allowed roots.
Call cubemx_create_ioc for a new board or MCU configuration. Use the exact CubeMX identifier. Use only a new output directory.
Find an existing IOC file with the host filesystem tools, or ask the user for its path. Call cubemx_inspect_ioc before you plan a change to that file.
Resolve the requested MCU functions and pins from the available technical evidence. Do not state that the MCP read a datasheet or schematic.
Call cubemx_plan_ioc_changes. Use pin_assignments and enabled_peripherals for structural changes. Use parameter_updates only for known IOC parameter keys.
Show the planned changes, diagnostics, and source hash. Get user approval before you call cubemx_apply_ioc_changes, unless the user already gave explicit approval for that exact plan.
Apply the same plan request with expected_source_sha256 from the approved plan. Keep CubeMX validation enabled. Do not set skip_cubemx_validation unless the user explicitly requests the bypass and accepts the risk.
Use cubemx_generate_project only for a new output directory. Use cubemx_plan_regeneration for an existing STM32CubeIDE project. Show its file changes before apply. Use only a successful preview. After approval, call cubemx_apply_regeneration with the same plan_request and the exact expected_plan_id, expected_source_manifest_sha256, and expected_planned_manifest_sha256 from that preview. Existing authorization for the exact plan is sufficient.
Check succeeded before you report a completed generation or regeneration operation. Report all warning and error diagnostics. Report the backup path after apply. Stop if recovery_required is true.
Treat output_directory as the complete generated container. Treat project_path as the Eclipse project root. Do not assume that these paths are equal.

What this file has done since we first saw it

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.
