protogrid MCP server

Which servers in the official MCP registry are protogrid's own, 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.protogrid/registryverified in the MCP registry

The registry name sits under protogrid.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
  • Its tools do every use case we checked: find an MCP server for sending email; check whether a server answers and needs a key.
  • Checked on 1 of the 7 days it takes to judge reliability.

Once connected

  • For "find an MCP server for sending email", the likely first call is search.
  • For "check whether a server answers and needs a key", the likely first call is check_server.
  • Parameters are untyped or undescribed in 2 of 5 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.

  • can do · check whether a server answers and needs a key
  • not sure · pick a PostgreSQL connector for database queries

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 (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). 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 →

Tools it offers5 tools · read 2026-10-26
  • search

    Hybrid (keyword + semantic) search over servers and their tools. Filter by connection class to keep only what you can reach autonomously (R0, R1).

  • get_server

    Official server.json plus connectability (class, remotes with auth/health, packages), current tools, trust breakdown and identity for one server name.

  • list_tools

    Every current tool of a server with full input/output schemas, paginated by tool name.

  • get_connection

    Minimal connection block for the preferred remote (or package) with ${SECRET} placeholders, formatted for a target client. Secrets are never accepted or returned.

  • check_server

    Probe a remote MCP server URL once, credential-free and without calling its tools, and get its quality checks and its readiness for the Claude and OpenAI directories. Pass `url` to start a check (waits up to 25 s for the result), or `id`…

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://api.protogrid.dev/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http protogrid https://api.protogrid.dev/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://api.protogrid.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.
