Integration details

Description

Protogrid is a public registry of MCP servers. Describe a task in plain words and it finds matching servers from the official MCP registry, tells you how each one connects (no sign-in, an API key, OAuth or a local package), and returns a ready-to-use configuration for clients such as Claude Code, Codex, Cursor or VS Code. Every server shows its tools, a change history of its tool definitions, and trust and quality scores built from our own credential-free checks. You can also check any remote MCP server URL for protocol support and directory readiness. protogrid is read-only: it never calls third-party tools and never asks for your credentials. Scores come from observable signals; no audit is implied.

Tools

5 tools agents can invoke

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` to read one. Quota: a few checks per hour anonymously, more with an API key.
check_server
Minimal connection block for the preferred remote (or package) with ${SECRET} placeholders, formatted for a target client. Secrets are never accepted or returned.
get_connection
Official server.json plus connectability (class, remotes with auth/health, packages), current tools, trust breakdown and identity for one server name.
get_server
Every current tool of a server with full input/output schemas, paginated by tool name.
list_tools
Hybrid (keyword + semantic) search over servers and their tools. Filter by connection class to keep only what you can reach autonomously (R0, R1).

How the directory, categories and Discoverability Score work.

Read the methodology

How do I improve Protogrid's ChatGPT Plugin discoverability?

The levers are the listing surface agents actually read: names, descriptions, keywords, tool metadata, and registry health. Which lever matters depends on where discovery breaks, which is what continuous measurement shows.
