Lake Shore Temperature Controller MCP Server

Let an AI agent read every sensor on your cryostat, check heater status, set setpoints, ramps, heater ranges and PID values, wait for the temperature to settle, and switch all heaters off on Lake Shore Cryotronics Model 335, 336 and 350 temperature controllers. Its 11 documented tools cluster into read & search, update, all, reconnect.

People who work with heater and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

One of 32 MCP servers published from k-dense-ai/lab-instrument-mcps. Stars and repository activity are shared across all of them. See all 32 →

01 · Install Lake Shore Temperature Controller

Claude Code

claude mcp add k-dense-ai-lab-instrument-mcps-servers-p -- uvx labmcp-lakeshore

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "k-dense-ai-lab-instrument-mcps-servers-p": {
      "command": "uvx",
      "args": [
        "labmcp-lakeshore"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

repo age created 2026-09-25 - young repo, little track record yet

license Apache-2.0 - declared in the repository

pypi package labmcp-lakeshore - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.K-Dense-AI is GitHub-verified and matches the repo owner

03 · What Lake Shore Temperature Controller can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

g. after it was power cycled or a cable was re-plugged), and set the P, I and D values of an output's control loop (Lake Shore conventions).

Capability map

Tools grouped from the project's README - what Lake Shore Temperature Controller lets an agent do.

read & search

4 tools - e.g. Return the most recent raw commands sent to / replies received from the instrument (newest last). Useful for debugging and for recording what was done.; Report which instrument is connected (identity…

update

4 tools - e.g. Set an output's heater range (each step is ~10x more power). Anything above 0 lets the output heat: in closed loop as the PID demands, in open loop at the front; Set the P, I and D values of an output's…

All

1 tool - e.g. Turn every output off (heater range 0 on outputs 1-4), like the front-panel All Off key, and stop any running wait. Reports the read-back range of each output a

all_heaters_off

Reconnect

1 tool - e.g. Close and re-open the connection to the instrument (e.g. after it was power cycled or a cable was re-plugged).

reconnect

Wait

1 tool - e.g. Wait until the control input of output has stayed within tolerance_k of the setpoint (and the setpoint is no longer ramping) for stable_for_s, or until timeout_

wait_for_stable_temperature

Limitations (from the README)

- Setting a setpoint does not start heating; the heater range does. With a range above 0 an output heats as its PID loop demands (closed loop) or at the manual output (open loop). Output modes and control inputs are configured on the front panel; the server does not change them, since pointing a loop at the wrong sensor can cause a thermal runaway. - Setpoints are always given in kelvin. SETP uses the preferred units

06 · Lake Shore Temperature Controller FAQ

Is Lake Shore Temperature Controller still maintained?

Yes - as of 2026-09-30, its last commit was 2026-09-26. We re-verify nightly.

What can Lake Shore Temperature Controller do?

g. after it was power cycled or a cable was re-plugged), and set the P, I and D values of an output's control loop (Lake Shore conventions).

How do I install Lake Shore Temperature Controller?

Run `uvx labmcp-lakeshore`. You can also paste the ready-made client config above.

Does Lake Shore Temperature Controller run locally?

Yes - it's a stdio server: it runs on your machine (via uvx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
