How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 10 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability57
- AI-judged instruction clarity (fair).Partial
- Tool/resource definitions use about 872 tokens (~87/item across 10 items; 10 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage71
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
- Structured output schemas are declared (20% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 10 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 11 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
Unverified: 1 category
A category scored 0 because we could not verify it: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

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 →
crosscheck_volumes ~85
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 %.

How do I install the Show, Don't Code MCP server?
Show, Don't Code is a hosted endpoint at https://pugarhuda--show-dont-code-web.us-east.modal.run/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

What is the Show, Don't Code MCP server?
Show, Don't Code is an MCP server listed in the public MCP registry as io.github.PugarHuda/show-dont-code. Lab video or protocols.io protocol to a simulator-checked Opentrons Flex/OT-2 protocol. This page covers its hosted endpoint (https://pugarhuda--show-dont-code-web.us-east.modal.run/mcp).
Is the Show, Don't Code MCP server safe to use?
Show, Don't Code scores 61 out of 100 on VerifyMCP. 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 Show, Don't Code MCP server expose?
Show, Don't Code exposes 10 tools: list_runs, get_run, get_protocol, get_protocol_designer, get_tube_labels, and 5 more. Their descriptions and schemas cost roughly 752 tokens of context every time the server is loaded.
Does the Show, Don't Code MCP server require authentication?
No. We connected to Show, Don't Code without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Show, Don't Code MCP server still maintained?
Show, Don't Code is still listed as active in the MCP registry. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
