PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

  • caisy_run_query

    Run one read-only GraphQL query against this project's Caisy external API. Use it for any field, filter (where), sort, nested connection or localized value. Mutations and subscriptions are refused. Caisy: POST https://cloud.caisy.io/api/e/v4/ /graphql with header x-caisy-apikey.

  • caisy_list_queries

    List the top-level read fields of this project's Caisy schema: one all list query per non-unique blueprint, one single-entry query per unique blueprint, and the asset query. Call it first to learn the blueprint API ids.

  • caisy_list_documents

    List document ids of one blueprint with Relay pagination (all (first, after)). Returns ids only: call caisy_run_query for the fields you need. Unique blueprints have no list query: use caisy_run_query with the blueprint's single-entry field.

  • caisy_list_assets

    List media assets (title and source URL) of this project, with Relay pagination. Use the cursor from pageInfo.endCursor to read further.

Common questions

Is Caisy MCP by usefulapi safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.2.3) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Caisy MCP by usefulapi

Use your Caisy account from Claude, Cursor, or any MCP client. Reads blueprints, documents and media assets of one Caisy project through read-only GraphQL queries. Hosted, no local install: connect with your own credentials.

Live endpoint: https://caisy.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://caisy.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http caisy https://caisy.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
{

"mcpServers": { "caisy": { "url": "https://caisy.usefulapi.io/mcp" } } }

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Caisy credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/caisy/

On first connect you provide your Caisy project ID (the UUID in your GraphQL endpoint URL) and your Caisy API key (Settings → Development → API Keys). The server validates it and stores it per user. No keys go in config files.
