No change was recorded against any check on this day. Stability & Change Management went from 30 to 33. That category is still filling its 30-day observation window: 9 days of observed history at the previous scan, 10 at this one. The score rises as the window fills, whether or not the server changes.

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
stop ~81
Immediately halt one motor, or ALL motors if ``motor`` is omitted. Use for "stop", "halt", or any sign something is wrong. Sends the firmware's emergency stop: motion halts and the move queue empties; holding torque remains. Use ``disable_mosfets`` afterwards to let the shaft spin freely.
| Name | Type | Req | Description |
|---|---|---|---|
| motor | – | – | – |
No output schema declared.
No examples provided.
system_reset ~161
System reset / go to the bootloader. The motor will reset immediately and will enter the bootloader. If there is no command sent within a short time, the motor will exit the bootloader and run the application from the beginning. [Firmware command "System reset", group: Basic Control.] NOTE: Reboots the motor (~2 s): position re-zeroes at the current shaft location, MOSFETs disable, fatal errors clear. Returns: success confirmation. motor: an alias number (e.g. 88), a 16-hex-digit unique ID (e.g. "0123456789ABCDEF"), or "all" to broadcast to every motor on the bus (broadcasts get no responses back).
| Name | Type | Req | Description |
|---|---|---|---|
| motor | string | yes | – |
No output schema declared.
No examples provided.
test_mode ~267
Set or trigger a certain test mode. This is a bit undocumented at the moment. Don't use this unless you are a developer working on test cases. Notable modes: 0 = clear all test modes; 1-9 = motor test modes; 10-13 = LED test modes (locks up the device); 14-73 = trigger fatal errors 0-59; 74 = set the overvoltage-protection threshold to 22 V (production test, should trip on a 24 V supply); 75 = set the overvoltage-protection threshold to 26 V (production test, should not trip on a 24 V supply). A system reset restores the default overvoltage threshold. [Firmware command "Test mode", group: Configuration.] NOTE: Developer/diagnostic modes; behavior depends on firmware internals. Parameters: - testMode: The test mode to use or trigger Returns: success confirmation. motor: an alias number (e.g. 88), a 16-hex-digit unique ID (e.g. "0123456789ABCDEF"), or "all" to broadcast to every motor on the bus (broadcasts get no responses back).
| Name | Type | Req | Description |
|---|---|---|---|
| motor | string | yes | – |
| testMode | integer | yes | – |
No output schema declared.
No examples provided.
time_sync ~185
Sends the master time to the motor so that it can sync its own clock (do this 10 times per second). [Firmware command "Time sync", group: Device Management.] Parameters: - masterTime (in seconds): The motor absolute time that the motor should sync to (in microseconds). Returns: - timeError: The error in the motor's time compared to the master time. - rccIcscr: The contents of the RCC-ICSCR register (holds the HSICAL and HSITRIM settings). motor: an alias number (e.g. 88), a 16-hex-digit unique ID (e.g. "0123456789ABCDEF"), or "all" to broadcast to every motor on the bus (broadcasts get no responses back).
| Name | Type | Req | Description |
|---|---|---|---|
| masterTime | number | yes | – |
| motor | string | yes | – |
No output schema declared.
No examples provided.
trapezoid_move ~208
Move immediately to the given position using the currently set speed (the speed is set by a separate command) [Firmware command "Trapezoid move", group: Motion Control.] NOTE: The displacement is RELATIVE to the current position. This QUEUES the move and returns immediately; poll get_n_queued_items for completion, or use move_to/move_relative which wait. Requires enable_mosfets first. Parameters: - displacement (in degrees): The displacement to travel. Can be positive or negative. - duration (in seconds): The time over which to do the move. Returns: success confirmation. motor: an alias number (e.g. 88), a 16-hex-digit unique ID (e.g. "0123456789ABCDEF"), or "all" to broadcast to every motor on the bus (broadcasts get no responses back).
| Name | Type | Req | Description |
|---|---|---|---|
| displacement | number | yes | – |
| duration | number | yes | – |
| motor | string | yes | – |
No output schema declared.
No examples provided.
vibrate ~133
Cause the motor to start to vary the voltage quickly and therefore to vibrate (or stop). [Firmware command "Vibrate", group: Device Management.] Parameters: - vibrationLevel: Vibration level (0 = turn off, 1 = turn on). Returns: success confirmation. motor: an alias number (e.g. 88), a 16-hex-digit unique ID (e.g. "0123456789ABCDEF"), or "all" to broadcast to every motor on the bus (broadcasts get no responses back).
| Name | Type | Req | Description |
|---|---|---|---|
| motor | string | yes | – |
| vibrationLevel | integer | yes | – |
No output schema declared.
No examples provided.
zero_position ~111
Make the current position the position zero (origin) [Firmware command "Zero position", group: Basic Control.] NOTE: Redefines the current shaft location as 0 degrees (no movement). Returns: success confirmation. motor: an alias number (e.g. 88), a 16-hex-digit unique ID (e.g. "0123456789ABCDEF"), or "all" to broadcast to every motor on the bus (broadcasts get no responses back).

Is the Gearotons M17 Servomotor MCP server safe to use?
Gearotons M17 Servomotor scores 54 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 20 September 2026.

What tools does the Gearotons M17 Servomotor MCP server expose?
Gearotons M17 Servomotor exposes 57 tools: list_serial_ports, connect, disconnect, detect_devices, list_motors, and 52 more. Their descriptions and schemas cost roughly 9,467 tokens of context every time the server is loaded.
Is the Gearotons M17 Servomotor MCP server still maintained?
Gearotons M17 Servomotor is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the Gearotons M17 Servomotor MCP server under?
Gearotons M17 Servomotor declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
