## 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 2026-10-18.

- **Endpoint Security**: 57/100
  - 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.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - 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**: 69/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 204 tokens (~51/item across 4 items; 4 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 67/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% 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 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## Install

### How do I install the SaltCrate Oracle MCP server?

SaltCrate Oracle is a hosted endpoint at https://saltcrate-oracle.fly.dev/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.

### 2026-10-17 (score 62, +1)

No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-10-16 (score 61, 0)

- [functional improvement] Stability: unverified → 0.03

### 2026-10-15 (score 61)

First indexed and scored.

## MCP tools (4)

### `fetch` (~57 tokens)

Get clean, readable text from a web page — boilerplate, navigation, and ads stripped — so you can work with the actual content. Returns the text plus title, content-type, HTTP status, and length.

Input parameters:

- `url` (string, required)

### `check_link` (~40 tokens)

Is this URL live right now? Returns HTTP status, the redirect chain, final URL, and round-trip latency in milliseconds.

Input parameters:

- `url` (string, required)

### `check_change` (~50 tokens)

Did this web page change since the last time it was checked? Hash-based change detection. First check reports 'new'; later checks report 'changed' or 'unchanged'.

Input parameters:

- `url` (string, required)

### `verify` (~57 tokens)

Does this source URL support a given claim? Returns a confidence score, matched terms, and the best supporting excerpt. Heuristic term-overlap — not semantic fact-checking.

Input parameters:

- `claim` (string, required)
- `source_url` (string, required)

### Is the SaltCrate Oracle MCP server safe to use?

SaltCrate Oracle scores 62 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 SaltCrate Oracle MCP server expose?

SaltCrate Oracle exposes 4 tools: fetch, check_link, check_change, verify. Their descriptions and schemas cost roughly 204 tokens of context every time the server is loaded.

### Does the SaltCrate Oracle MCP server require authentication?

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

### Is the SaltCrate Oracle MCP server still maintained?
