## 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 2026-09-25.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - 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**: 81/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 232 tokens (~116/item across 2 items; 2 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 7/100
  - Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 95/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 86% 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 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 2 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.

### How do I install the Crela MCP server?

## MCP tools (2)

### `search_software` (~171 tokens)

Search Crela software

Search the Crela marketplace for reviewed software, apps and games you buy once and own - no subscription. Returns only approved, publicly listed tools, each with a url to its Crela page where it can be bought. Use limit (1-50) to keep the response small and page through the rest; get_software returns the full detail of one.

Input parameters:

- `category` (string)
- `lang` (string): Language of the software user interface, e.g. "de". Not the programming language.
- `limit` (integer): Results per page, default 20
- `page` (integer): 1-based page, see total_pages in the response
- `query` (string): Full-text search over title and description
- `sort` (string): Result ordering, default "latest"

### `get_software` (~61 tokens)

Get Crela software details

Full public detail of one approved software item by its slug: description, price, platforms, version, system requirements and the url of its Crela page.

Input parameters:

- `slug` (string, required): The software slug from search_software, e.g. "knowledge-editor"

## Common questions

### What is the Crela MCP server?

Crela is an MCP server listed in the public MCP registry as io.crela/mcp. Search the Crela software marketplace and publish, update and review your software from your agent. This page covers its hosted endpoint (https://crela.io/mcp).

### Is the Crela MCP server safe to use?

Crela scores 75 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 Crela MCP server expose?

Crela exposes 2 tools: search_software, get_software. Their descriptions and schemas cost roughly 232 tokens of context every time the server is loaded.

### Does the Crela MCP server require authentication?

No. We connected to Crela without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Crela MCP server still maintained?

Crela is still listed as active in the MCP registry. We last reached this channel on 25 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
