SaltCrate MCP server

Which MCP servers are SaltCrate's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Registry namecom.saltcrate/oracleverified in the MCP registry

The registry name sits under saltcrate.com. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-27 the server answered initialize and tools/list without a sign-in. First answer in 188 ms.

  • Whether its tools do the product's job has not been judged yet.

Once connected

  • Parameters are untyped or undescribed in 4 of 4 tools: check arguments before calling.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Worth a look

None of the five warning signs in these definitions.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

  • fetch

    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.

  • check_link

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

  • check_change

    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'.

  • verify

    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.

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "oracle": {
      "type": "http",
      "url": "https://saltcrate-oracle.fly.dev/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http saltcrate https://saltcrate-oracle.fly.dev/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://saltcrate-oracle.fly.dev/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
