LightRay MCP server

Which MCP servers are LightRay'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 nameai.lightray/lightrayverified in the MCP registry

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

On 2026-10-31 the server answered initialize and tools/list without a sign-in. First answer in 117 ms.

Should an agent connect itNot proven either way yet
  • Its tools do every use case we checked: Look up a company's background before a meeting; Check a company's name and city over WhatsApp.
  • Checked on 4 of the 7 days it takes to judge reliability.

Once connected

  • For "Look up a company's background before a meeting", the likely first call is check_company.
  • For "Check a company's name and city over WhatsApp", the likely first call is check_company.

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.

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 →

  • list_reports

    Use this to see the reader's recent reports from here, newest first, each with whether it is ready and its link. It uses none of the reader's reports.

How to connect

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

{
  "mcpServers": {
    "lightray": {
      "type": "http",
      "url": "https://app.lightray.ai/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http lightray https://app.lightray.ai/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://app.lightray.ai/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.
