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 →
all_off All Off ~82
Put the RGA in a safe state: abort any degas, CDEM off (HV0), filament off (FL0) and quadrupole RF/DC off (MR0). Use when finished, before venting, or if anything looks wrong. It interrupts a running scan or leak check, and every step is attempted even if an earlier one fails.
Input schema present but exposes no named parameters.

analog_scan Analog Scan ~173
Record an analog mass spectrum (SC1): the quadrupole steps through the mass range and the full peak shapes are returned (downsampled) with a peak list, the total pressure measured at the end of the scan, and optionally the full data as CSV. Use it to check peak positions and to survey unknown gases. Duration depends on the noise floor (e.g. 126 ms/amu at NF4). An existing save_path file is never overwritten.

No examples provided.
calibrate Calibrate ~112
Calibrate the detector: `zero` (CA) re-zeroes the ion detector at the present noise floor and detector and corrects the RF scan table for temperature drift (seconds); `electrometer` (CL) recalibrates the electrometer's full I-V response (longer, clears all zero offsets). The quadrupole RF is switched off at the end.

cdem_off Cdem Off ~44
Switch the electron multiplier off (HV0) and return to Faraday-cup detection. Always allowed, and it interrupts a running scan, mass measurement or leak check.

degas Degas ~153
Start an ionizer degas (DG): 20 mA of 400 eV electrons clean the ion source by electron stimulated desorption. The CDEM is switched off and left off. Degassing shortens filament life; prefer a bakeout. Refused above `max_filament_pressure_torr` and beyond `max_degas_minutes`. Returns immediately; the RGA is busy until it finishes (any command would abort it), and `filament_off` / `all_off` stop it.

Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.

get_status Get Status ~83
Report the RGA state: filament emission, CDEM on/off and voltage, ionizer settings, scan settings, stored sensitivity factors, and the decoded error bytes (e.g. FL6 when the overpressure protection shut the filament down).

histogram_scan Histogram Scan ~85
Record a bar-graph spectrum (HS1): one peak-locked value per integer m/z plus the total pressure. Faster than an analog scan and the usual way to follow a residual gas composition.

identify_residual_gases Identify Residual Gases ~130
Run a histogram scan and assign the major peaks to likely gases with a simple lookup of standard 70 eV fragment patterns: H2 (2), He (4), CH4 (16/15), H2O (18/17), N2 or CO (28, split with 14 and 12), O2 (32), Ar (40), CO2 (44), plus diagnoses such as an air leak or hydrocarbon contamination.

leak_check Leak Check ~191
Helium leak check: monitor m/z 4 while someone sprays helium on suspect joints, and report the baseline, every response above `threshold_factor` x baseline (start/end time, peak) and the time series. Keep the first few seconds free of helium so the baseline is clean. The response time of a real leak is a few seconds. Bounded by `max_leak_check_duration_s`.
| Name | Type | Req | Description |
|---|---|---|---|
| baseline_points | integer | – | Readings used for the baseline |

measure_masses Measure Masses ~97
Measure partial pressures at a list of m/z values (peak-locked single-mass measurements, MR). Fast and precise for monitoring known gases; the precision and time per mass are set by the noise floor (`set_scan_parameters`). Pressures are N2-equivalent.
| Name | Type | Req | Description |

| warnings | array | – | – |
No examples provided.
read_total_pressure Read Total Pressure ~71
Measure the total pressure with the RGA acting as an ionisation gauge (TP?, Faraday cup). Needs the filament on and the CDEM off. The value is N2-equivalent and can differ from a Bayard-Alpert gauge by a factor of a few, depending on the gas composition.
Input schema present but exposes no named parameters.
| Name | Type | Req | Description |
|---|---|---|---|
| filament_on | boolean | yes | – |
| ion_current_a | number | yes | – |

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_cdem Set Cdem ~166
Switch the electron multiplier (CDEM) on at a given high voltage for ~100-10000x more signal. High pressure shortens CDEM life and can destroy it, so this is refused unless the pressure is below `max_cdem_pressure_torr` (RGA total pressure measured now with the Faraday cup, a recent one, or `external_pressure_torr`), and the voltage is capped by `max_cdem_voltage_v`. Total-pressure readings are disabled while the CDEM is on.

| external_pressure_torr | – | – | Pressure just read on a separate vacuum gauge, confirmed by the user |
| voltage_v | integer | – | CDEM high voltage (magnitude); typical 1000-1600 V, default 1400 |

| pressure_evidence | – | – | – |
| status_byte | integer | yes | – |
| timestamp | string | yes | – |
No examples provided.
set_filament Set Filament ~153
Switch the filament on (or change its emission current). The filament burns out or is damaged above 1e-4 Torr, so this is refused unless the pressure is below `max_filament_pressure_torr`: pass `external_pressure_torr` from a separate gauge, or, if the filament is already on, the RGA's own total pressure is measured. The RGA's protection will also shut the filament down on overpressure (reported as FL6).
| Name | Type | Req | Description |
|---|---|---|---|
| emission_current_ma | number | – | Electron emission current; 1.0 mA is the standard setting |
| external_pressure_torr | – | – | Pressure just read on a separate vacuum gauge, confirmed by the user |

| pressure_evidence | – | – | – |
| status_byte | integer | yes | – |
| timestamp | string | yes | – |
No examples provided.
set_scan_parameters Set Scan Parameters ~172
Change measurement settings: noise floor (speed vs detection limit), electron energy, ion energy, focus plate voltage and analog-scan resolution. Sensitivity factors stored in the head are only valid at the default ionizer settings (70 eV, 12 eV, 90 V). After changing the noise floor the detector zero is re-adjusted automatically at the start of the next scan.

What is the SRS Residual Gas Analyzer MCP server?
SRS Residual Gas Analyzer is an MCP server listed in the public MCP registry as io.github.K-Dense-AI/labmcp-srs-rga. MCP server for SRS RGA100/200/300 residual gas analyzers. This page covers its PyPI package (labmcp-srs-rga).
Is the SRS Residual Gas Analyzer MCP server safe to use?
SRS Residual Gas Analyzer scores 83 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 SRS Residual Gas Analyzer MCP server expose?
SRS Residual Gas Analyzer exposes 18 tools: get_connection_info, get_command_log, reconnect, get_status, read_total_pressure, and 13 more. Their descriptions and schemas cost roughly 1,875 tokens of context every time the server is loaded.
Is the SRS Residual Gas Analyzer MCP server still maintained?
SRS Residual Gas Analyzer 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 SRS Residual Gas Analyzer MCP server under?
SRS Residual Gas Analyzer 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.
