Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Runs an external command sdc/export.py:334, sdc/meta.py:106, sdc/protocol.py:433 и ещё 2

        p = subprocess.run([sys.executable, str(script)], capture_output=True, text=True, timeout=timeout,

Page executes code built at runtime web/index.html:385, web/landing.html:422

  $("run").innerHTML = runs.map((n) => `<option value="${esc(n)}">${esc(label(n))}</option>`).join("");

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 10

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

protocol

get_protocol

The generated Opentrons Flex protocol (Python, API 2.24), ready to import into the Opentrons App.

get_protocol_designer

The protocol as an Opentrons Protocol Designer file: import it at designer.opentrons.com to edit each step (transfers, mixes, the thermocycler program) without code. The Opentrons App can also run it as is.

bench

get_bench_card

The illustrated bench card for training: each filmed step drawn by Muse Image from its own video frame (an edit of the real frame, no text drawn in), Muse Spark's check that the drawing kept every object, and the step's reagent and volume from the protocol. Image links are under /api/runs/<name>/bench-card/<step>.jpg.

crosscheck

crosscheck_volumes

This run's per-reaction volumes next to those of published protocols.io protocols that use the same kit, read by Muse Spark: each match has the published volume, its verbatim quote (checked to be in the protocol's text), both reagents' share of the reaction and whether they agree within 20 %.

flex

run_on_flex_robot_server

Run the run's protocol.py end to end on Opentrons' own robot-server (the software inside a Flex, v10.1.0) in Flex simulation, with the Reactions parameter set: the robot's analysis, deck configuration, play to the end. Returns the robot's report (status 'succeeded', command count). About a minute the first time, then cached. Runs only the protocol this server generated, never code an agent sends.

get

get_run

The steps found in the video (with video seconds), the open questions, and the Opentrons simulator and protocol analysis results, including the deck setup, runtime parameters and the thermocycler's minimum time in seconds.

receipt

get_receipt

Reproducibility receipt: SHA-256 of the protocol, the video and every model output, and which models ran, anchored in Bitcoin with OpenTimestamps ('timestamp': pending calendars, or the confirming block).

get_related_protocols

Public protocols on protocols.io that use this run's reagents (brand and kit names) and protocol type, with DOIs and which reagent words each mentions: how other labs wrote up the same kit.

runs

list_runs

Names of the sample runs (videos already turned into protocols).

tube

get_tube_labels

The tubes to load on the tube rack before the run: each tube's deck slot and well, how many µL to fill a source tube with (what the robot draws + 10 % + dead volume) for `reactions` copies of the filmed reaction (protocol.py's Reactions parameter, up to max_reactions), and the link its label's QR code opens. Links to the printable labels: an Avery L7160 sheet (SVG) and a Zebra thermal printer file (ZPL, 2 x 1 in).

Show, Don't Code — questions

Answers built from our own checks of this server.

What can Show, Don't Code do?

It exposes 10 tools, read directly from the server on our last check. Among them: crosscheck_volumes, get_bench_card, get_protocol, get_protocol_designer, get_receipt, get_related_protocols and 4 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Show, Don't Code working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 92 checks got a reply (0.0%), average response time 5401 ms. The bar chart above shows every period we have measured.

The registry lists Show, Don't Code as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Show, Don't Code?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Show, Don't Code need an API key?

No. Show, Don't Code completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 10 of them are readable on this page. This is what we observed, not what the docs claim.

Is Show, Don't Code open source?

The code is open source: it is published under the MIT licence, written in Python and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at pugarhuda--show-dont-code-web.us-east.modal.run, which runs on its operator's own terms.
