No change was recorded against any check on this day. Stability & Change Management went from 10 to 13. That category is still filling its 30-day observation window: 3 days of observed history at the previous scan, 4 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 →

run_methodscript Run Methodscript ~217
Advanced: run a raw MethodSCRIPT and return its raw output and decoded data packages. Literal potentials of set_e / set_range_minmax da and the CV, LSV, DPV, SWV, NPV, ACV, CA, PAD, EIS and fast CV/CA techniques are checked against `max_potential_v`, and literal `set_range ba` / `set_autoranging ba` currents against `max_current_range_a`; values computed at run time are not. Aborted after `timeout_s`; add `on_finished:` + `cell_off` to your script so the cell is switched off after an abort. After a runtime error, a timeout or `abort_measurement` the server switches the cell off itself.

Is the PalmSens Potentiostat MCP server safe to use?
PalmSens Potentiostat scores 82 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 PalmSens Potentiostat MCP server expose?
PalmSens Potentiostat exposes 10 tools: get_connection_info, get_command_log, reconnect, get_device_info, run_cyclic_voltammetry, and 5 more. Their descriptions and schemas cost roughly 1,364 tokens of context every time the server is loaded.
Is the PalmSens Potentiostat MCP server still maintained?
PalmSens Potentiostat 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 PalmSens Potentiostat MCP server under?
PalmSens Potentiostat 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.
