Assay MCP server

Which MCP servers are Assay'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 nameio.goassay/assayverified in the MCP registry

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

When we asked itchecked 2026-10-28
  • Staterequires sign-inchecked 2026-10-28

On 2026-10-28 the server answered and asked for a sign-in with a Assay account (OAuth). It shows its tool list only to signed-in users, so we list none here.

How to connect

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

{
  "mcpServers": {
    "assay": {
      "type": "http",
      "url": "https://app.goassay.io/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http goassay https://app.goassay.io/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://app.goassay.io/mcp as a custom connector in the settings.

The first time it connects, the client opens a Assay sign-in.

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.
