## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-23.

- **Endpoint Security**: 51/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (genmc_call).
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 68/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 786 tokens (~196/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 30/100
  - Stability observed for 9 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (4)

### `genmc_pair` (~207 tokens)

Pair with a genMC studio tab

Connect to the user's open genMC studio tab. The user sees a code like "K7Q-4MX" after choosing "Connect agent" in the studio header. Pairing returns a resumeKey: if your MCP connection drops or restarts (an unknown session, a failed server), call genmc_pair with that resumeKey instead of asking the user for a new code. Resuming from another MCP session (a second client, a script) attaches it in addition: all your sessions reach the same tab. After pairing, the tab's WebMCP tools (skins, builds, whichever studio is open) appear in your tool list; if your client does not refresh it, use genmc_status and genmc_call.

Input parameters:

- `code` (string): Pairing code shown in the studio, e.g. K7Q-4MX.
- `resumeKey` (string): Key from an earlier genmc_pair result; reconnects to the same tab without a new code.

### `genmc_status` (~81 tokens)

genMC connection status

Show whether you are paired with a genMC studio tab, whether it is reachable, which studio page it shows and which tools it offers. Call it when studio tools are missing from your tool list (the user switched studios): its answer also brings your tool list up to date.

Input parameters:

- `includeSchemas` (boolean): Also return every tool description and input schema.

### `genmc_call` (~67 tokens)

Call a studio tool

Call any tool of the paired studio tab by name. Use it when your tool list has not refreshed after pairing or after the user switched studios; otherwise call the tool directly.

Input parameters:

- `input` (object): Tool arguments.
- `name` (string, required): Tool name, see genmc_status.

### `genmc_docs` (~227 tokens)

genMC knowledge base

Search and read the genMC knowledge base: how every studio, tool, button, limit and workflow works (skins, builds, agents and pairing, accounts and sharing, export, shortcuts, troubleshooting). Call it without arguments for the table of contents, with query to search (best matching articles with a snippet and the matching section), or with article (a slug from the contents or a search result) to read one article in full as Markdown. Links written as doc:<slug> point to other articles. Use it when you are unsure how a feature works, what a label in the studio means, or how to explain something to the user. Read-only; it never changes the studio.

Input parameters:

- `article` (string): Slug of the article to read in full, e.g. "connect-agent".
- `lang` (string): Language of the articles: en (default) or de.
- `limit` (integer): Maximum number of search results (default 8).
- `query` (string): Words to search for, e.g. "secret link" or "export schematic".
