Available components
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security99
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- Runs hatchling.build at install time, a recognised build step with no custom scripting around it. View diagnostics → Pass
- 2 of 17 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency100
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass

- 29 Sept 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 at this one. The score rises as the window fills, whether or not the server changes.

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.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | – |
| Name | Type | Req | Description |
|---|---|---|---|
| result | array | yes | – |
No examples provided.
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.
lock_keypad Lock Keypad ~53
Block or unblock the balance keys, e.g. so nobody tares by accident during a long logging run.
| Name | Type | Req | Description |
|---|---|---|---|
| locked | boolean | yes | True blocks the balance keys (ESC O), False unblocks (ESC R) |
| Name | Type | Req | Description |
|---|---|---|---|
| result | string | yes | – |
No examples provided.
log_weight_series Log Weight Series ~61
Record a series of immediate (unfiltered) readings to monitor drift, evaporation, moisture uptake or stabilisation. Returns every reading plus summary statistics.
| Name | Type | Req | Description |
|---|---|---|---|
| count | integer | – | Number of readings |
| interval_s | number | – | Seconds between readings |

| mean | number | yes | – |
| minimum | number | yes | – |
| readings | array | yes | – |
| stdev | number | yes | – |
| unit | – | yes | – |
No examples provided.
read_weight Read Weight ~95
Read the current net weight from the balance (ESC P). With stable=True the server polls until the balance reports a stable value; if it cannot settle (draughts, vibration, evaporation) you get an error; retry, or use stable=false for the current value.
| Name | Type | Req | Description |
|---|---|---|---|
| stable | boolean | – | Wait for a stable reading (recommended) |
| timeout_s | number | – | Max. seconds to wait for stability |
| Name | Type | Req | Description |
|---|---|---|---|
| id_code | string | yes | SBI 22-character-format ID code (e.g. 'N' = net); '' in 16-character format |
| stable | boolean | yes | True if the balance marked the reading as stable |
| timestamp | string | yes | UTC time the reading was taken (ISO 8601) |
| unit | – | yes | Unit sent by the balance (e.g. 'g'). SBI omits it for unstable readings; then this is the last unit seen, or None |
| value | number | yes | Net weight value |
No examples provided.
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.
run_internal_adjustment Run Internal Adjustment ~101
Adjust (calibrate) the balance with its built-in weight (ESC Z; isoCAL models only). The pan must be empty and the balance undisturbed. SBI sends no completion message, so the server watches for the adjustment status and waits until the balance weighs again; check `observed_adjustment` and the balance display or GLP printout for the result.
| Name | Type | Req | Description |
|---|---|---|---|
| timeout_s | number | – | Max. seconds for the adjustment |
| Name | Type | Req | Description |
|---|---|---|---|
| duration_s | number | yes | – |
| final_reading | – | yes | – |
| message | string | yes | – |
| observed_adjustment | boolean | yes | True if the balance reported an adjustment in progress (Cal.* status or busy) |
No examples provided.
set_ambient_conditions Set Ambient Conditions ~60
Adapt the balance's filter to the ambient conditions (ESC K/L/M/N). Use 'unstable' or 'very_unstable' for draughty or vibrating benches (slower but steadier readings).
| Name | Type | Req | Description |
|---|---|---|---|
| conditions | string | yes | – |
| Name | Type | Req | Description |
|---|---|---|---|
| result | string | yes | – |
No examples provided.
tare Tare ~74
Tare the balance (ESC U, or ESC T on legacy balances): the current load (e.g. an empty container) becomes the tare. Then waits for a stable reading and checks that it is ~0; returns that reading.
| Name | Type | Req | Description |
|---|---|---|---|
| timeout_s | number | – | Max. seconds to wait for the tared reading |
| Name | Type | Req | Description |
|---|---|---|---|
| id_code | string | yes | SBI 22-character-format ID code (e.g. 'N' = net); '' in 16-character format |
| stable | boolean | yes | True if the balance marked the reading as stable |
| timestamp | string | yes | UTC time the reading was taken (ISO 8601) |
| unit | – | yes | Unit sent by the balance (e.g. 'g'). SBI omits it for unstable readings; then this is the last unit seen, or None |
| value | number | yes | Net weight value |
No examples provided.
zero Zero ~64
Zero the balance (ESC V). Only works with the pan (nearly) empty, within the balance's zero-setting range; clears the tare. Confirms by reading ~0 afterwards.
| Name | Type | Req | Description |
|---|---|---|---|
| timeout_s | number | – | Max. seconds to wait for the zeroed reading |
| Name | Type | Req | Description |
|---|---|---|---|
| id_code | string | yes | SBI 22-character-format ID code (e.g. 'N' = net); '' in 16-character format |
| stable | boolean | yes | True if the balance marked the reading as stable |
| timestamp | string | yes | UTC time the reading was taken (ISO 8601) |
| unit | – | yes | Unit sent by the balance (e.g. 'g'). SBI omits it for unstable readings; then this is the last unit seen, or None |
| value | number | yes | Net weight value |

What tools does the Sartorius Balance MCP server expose?
Sartorius Balance exposes 10 tools: get_connection_info, get_command_log, reconnect, read_weight, log_weight_series, and 5 more. Their descriptions and schemas cost roughly 629 tokens of context every time the server is loaded.
Is the Sartorius Balance MCP server still maintained?
Sartorius Balance 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.
