Desvela MCP server

Which MCP servers are Desvela'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 namedev.desvela/registryverified in the MCP registry

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

Should an agent connect itNot proven either way yet

Whether its tools do the product's job has not been judged yet.
Checked on 1 of the 7 days it takes to judge reliability.

Once connected

Parameters are untyped or undescribed in 3 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.

What an agent can do with it

not sure · measure how often AI engines mention your brand
not sure · schedule recurring checks and get alerts on visibility changes
not sure · let an AI agent run and summarize brand checks via MCP

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

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 →

How to connect

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

{
  "mcpServers": {
    "registry": {
      "type": "http",
      "url": "https://registry.desvela.dev/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http desvela https://registry.desvela.dev/mcp

Add to Cursor Add to VS Code

claude.ai, ChatGPT and other clients: add https://registry.desvela.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.
