## 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 2026-09-22.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 4 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - 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**: 84/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 400 tokens (~100/item across 4 items; 4 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 13/100
  - Stability observed for 4 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.

## Install

### How do I install the Spark Apps Catalogue MCP server?

Spark Apps Catalogue is a hosted endpoint at https://spark-apps.co/api/mcp/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.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-09-21 (score 70, +1)

No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-09-19 (score 69, +1)

- [functional improvement] Stability: unverified → 0.03

### 2026-09-18 (score 68)

First indexed and scored.

## MCP tools (4)

### `list_apps` (~63 tokens)

List every app in the Spark catalogue: id, name, tagline, description, tags, homepage and store or repository links. Read-only. Small enough to read in full, so prefer this over search when the question is about the range of apps rather than a specific one.

### `get_app` (~79 tokens)

Get one app from the Spark catalogue by its id, with its full description, tags and links. Read-only. If the id is unknown the result lists every valid id, so there is no need to guess twice.

Input parameters:

- `id` (string, required): The app's catalogue id, e.g. sparkstack or sparkmobile. Lowercase, no spaces.

### `search_apps` (~102 tokens)

Search the Spark catalogue by keyword across app names, taglines, descriptions and tags, optionally narrowed to a single tag. Read-only. Pass an empty query with a tag to list everything carrying that tag.

Input parameters:

- `query` (string, required): Words to look for. Matched as a substring; pass an empty string to match all.
- `tag` (string): Restrict to one tag, e.g. Next.js or Mobile. Use list_tags to see valid tags.

### `list_tags` (~43 tokens)

List every tag used across the Spark catalogue with how many apps carry it, most used first. Read-only. Use this before search_apps to pick a tag that actually exists.
