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 →
get_command_log Get Command Log ~46
Return the most recent raw commands sent to / replies received from the instrument (newest last). Useful for debugging and for recording what was done.

get_connection_info Get Connection Info ~40
Report which instrument is connected (identity, address, simulated or real), whether the server is read-only, and the active safety limits. Call this first.
Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.
No examples provided.
get_errors Get Errors ~41
Read (and clear) the controller's ERROR word: controller error, no hardware, inadmissible parameter or syntax error. An empty list means no error.
Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.

| Name | Type | Req | Description |
|---|---|---|---|
| result | array | yes | – |
No examples provided.
log_pressure_series Log Pressure Series ~155
Log pressures at a fixed interval (e.g. a pump-down curve, leak-up/rate-of-rise test or bake-out). Returns per-channel statistics in log-space plus a downsampled series; the full series can be written to a new CSV file (an existing file is never overwritten). Bounded by `max_log_duration_s` and 2 h per call.
| Name | Type | Req | Description |

|---|---|---|---|
| channel | integer | – | Measurement channel (gauge) number |
| Name | Type | Req | Description |
|---|---|---|---|
| channel | integer | yes | – |
| pressure | – | yes | Pressure in `unit`; null unless status is ok |

reconnect Reconnect ~35
Close and re-open the connection to the instrument (e.g. after it was power cycled or a cable was re-plugged).
Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.
No examples provided.
set_gauge_power Set Gauge Power ~160
Switch an ionisation gauge (IKR, PKR, PBR, IMR) on or off (SEN). Switching a hot or cold cathode gauge on at high pressure can burn out the filament or contaminate the gauge, so switching ON is refused unless a valid reading from this gauge or `reference_channel` is at or below `max_switch_on_pressure_mbar`. Switching off may trip setpoint relays used as interlocks.
| Name | Type | Req | Description |
|---|---|---|---|
| channel | integer | yes | Channel of the ionisation gauge |
| on | boolean | yes | True = switch the gauge on, False = off |
| reference_channel | – | – | Another gauge on the same vacuum (e.g. a Pirani) used to check the pressure |
| Name | Type | Req | Description |
|---|---|---|---|
| result | array | yes | – |
No examples provided.
set_unit Set Unit ~59
Change the pressure unit used on the display and interface (UNI). Readings in mbar are always included regardless of this setting.

Structured output declared, but exposes no named fields.
No examples provided.
switch_gauge_off Switch Gauge Off ~65
Switch an ionisation gauge off (e.g. before venting, or if the pressure is rising). Always allowed. Note that setpoint relays assigned to this channel may change state.
| Name | Type | Req | Description |
|---|---|---|---|
| channel | integer | yes | Channel of the ionisation gauge to switch off |
| Name | Type | Req | Description |

What is the Pfeiffer Vacuum Gauge Controller MCP server?
Pfeiffer Vacuum Gauge Controller is an MCP server listed in the public MCP registry as io.github.K-Dense-AI/labmcp-pfeiffer-tpg. MCP server for Pfeiffer Vacuum TPG 361/362/366 and TPG 261/262 gauge controllers. This page covers its PyPI package (labmcp-pfeiffer-tpg).
Is the Pfeiffer Vacuum Gauge Controller MCP server safe to use?
Pfeiffer Vacuum Gauge Controller scores 68 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 30 September 2026. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Pfeiffer Vacuum Gauge Controller MCP server expose?
Pfeiffer Vacuum Gauge Controller exposes 11 tools: get_connection_info, get_command_log, reconnect, read_pressure, read_all_pressures, and 6 more. Their descriptions and schemas cost roughly 713 tokens of context every time the server is loaded.
Is the Pfeiffer Vacuum Gauge Controller MCP server still maintained?
Pfeiffer Vacuum Gauge Controller is still listed as active in the MCP registry. We last reached this channel on 30 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 Pfeiffer Vacuum Gauge Controller MCP server under?
Pfeiffer Vacuum Gauge Controller declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
