Overview

Description from the maker (original English)

Signed-in CloudSprite: search datasets and docs, set org/team/project scope, file feedback.

PopNx MCP’s three pillars

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

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Search & AI memory

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

You need

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Common questions

Is CloudSprite safe?

It passed 1 of 1 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 (0.1.3) reached the registry 2 months ago.

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?

In the same category: Context7, Codebase Memory, Exa

CloudSprite plugin

Public plugin for CloudSprite. One repo, one plugin slug (cloudsprite), for Claude Code, Grok Build, and Agent Plugins clients (Cursor, GitHub Copilot, VS Code, Codex, and others).

The plugin talks to production CloudSprite over remote MCP. There are no API keys, GitLab tokens, Linear tokens, or other secrets in this repository. OAuth tokens stay in the client.

Plugin name is cloudsprite and is immutable once a marketplace lists it. The GitHub org is cloudsprite-io because cloudsprite was already taken on GitHub.

Connect your AI to CloudSprite

Full per-client steps: Connect your AI to CloudSprite.

There is no API key in this repo and none in chat. Sign in with the same CloudSprite account you use in the browser.

| What | Value | |-|-| | MCP URL | https://api.cloudsprite.io/mcp | | Transport | Streamable HTTP | | OAuth discovery | https://api.cloudsprite.io/.well-known/oauth-authorization-server | | Plugin slug | cloudsprite (fixed) |

How do I connect Claude Code to CloudSprite?
/plugin marketplace add cloudsprite-io/cloudsprite-plugin

/plugin install cloudsprite@cloudsprite

Enable the cloudsprite plugin if it is not already on. On first tool use, complete the browser sign-in.

How do I connect Cursor, GitHub Copilot, VS Code, or Codex to CloudSprite?

This repo is an Agent Plugins 1.0 package: root plugin.json, mcp.json, and skills/.

  1. Clone this repository (or add cloudsprite-io/cloudsprite-plugin as the plugin source if your client accepts a git URL).
  2. Load it as an Agent Plugin. In Cursor, a local checkout under ~/.cursor/plugins/local/cloudsprite is enough.
  3. Enable the plugin and complete OAuth when the client prompts.

If the client cannot load Agent Plugins, add a remote MCP server instead (same URL and OAuth as any MCP client).

How do I connect Grok to CloudSprite?
grok plugin marketplace add cloudsprite-io/cloudsprite-plugin

grok plugin install cloudsprite --trust

Official listing on xAI’s marketplace is separate and not required for this install. Maintainer catalog notes: DIRECTORY.md.

How do I connect any MCP client to CloudSprite?

| Setting | Value | |-|-| | Server URL | https://api.cloudsprite.io/mcp | | Transport | Streamable HTTP | | OAuth discovery | https://api.cloudsprite.io/.well-known/oauth-authorization-server |

The client must discover authorization, token, and JWKS URLs from that metadata. Do not hard-code those hosts, and do not put a client secret or API key in the config.

{

"mcpServers": { "cloudsprite": { "type": "streamable-http", "url": "https://api.cloudsprite.io/mcp" } } }

Some clients use "type": "http" or a bare "url" field for the same remote server.

How do I connect ChatGPT to CloudSprite?

ChatGPT connectors are coming soon. Do not add CloudSprite as a ChatGPT custom connector yet — that OAuth redirect is not registered. Use Claude Code, Cursor, Copilot, Codex, Grok, or a generic MCP client today.

What it does

After you sign in and set scope, the model can:

  • Read org / team / project context (whoami / get_scope, list_orgs, list_teams, list_projects, set_scope)
  • Search datasets, traces (summaries only), notebooks, and scripts
  • Search CloudSprite product docs and the SDK catalog (search_knowledge, search_sdk)
  • File a bug or feature request (/feedback → MCP submit_feedback)

This release is read-only plus feedback. It does not mutate datasets, tags, notebooks, or scripts.

MCP URL

Production (the only URL customers use):

https://api.cloudsprite.io/mcp

Transport: MCP Streamable HTTP. No Authorization header is stored in the plugin. The client discovers OAuth from the MCP origin and holds the tokens. There is no environment picker in the plugin UI.

A 401 from /mcp before OAuth is live is expected. The plugin should fail with a clear auth error, not hang.

Claude Code honors CLOUDSPRITE_MCP_URL if the client process has it set (${CLOUDSPRITE_MCP_URL:-https://api.cloudsprite.io/mcp} in .mcp.json). The GUI app reads ~/.claude/settings.json "env", not your shell profile. Portable mcp.json is a literal production URL (no interpolation). Do not commit a .env here.

Skills

| Skill | Slash | Purpose | |-|-| | feedback | /feedback | Confirm text, then call MCP submit_feedback | | platform-howtos | /platform-howtos | Sign-in, scope, and how to use CloudSprite from the assistant | | datasets | /datasets | Find datasets, parameters, tags, and notebooks (read) | | mixed-mode-analysis | /mixed-mode-analysis | Differential / common-mode S-parameters from 2-port pairs | | waveform-correlation | /waveform-correlation | Pairwise Pearson QC across repeated traces |

Network endpoints

The plugin package does not open sockets itself. Clients that load it will contact:

| URL | Why | |-|-| | https://api.cloudsprite.io/mcp | MCP Streamable HTTP (tools) | | https://api.cloudsprite.io/.well-known/oauth-authorization-server | OAuth 2.1 authorization-server metadata | | https://api.cloudsprite.io/.well-known/oauth-protected-resource | OAuth protected-resource metadata (if advertised) | | Authorization, token, revocation, and JWKS URLs from that metadata | Cognito Hosted UI PKCE. Hosts are not hardcoded here; they come from discovery. |

Installing the plugin also clones this GitHub repository (https://github.com/cloudsprite-io/cloudsprite-plugin). Tagged releases are vMAJOR.MINOR.PATCH matching plugin.json version.

The plugin does not call GitLab, Linear, HubSpot, or any issue tracker. Feedback is filed by the CloudSprite API after submit_feedback.

If CLOUDSPRITE_MCP_URL is set, discovery and token endpoints follow that host instead of api.cloudsprite.io.

Support

Releases

Git tags are v + the version in plugin.json (currently 0.1.3). Maintainers publish with scripts/publish.sh after scripts/audit.sh passes. Republishing the same tag is a no-op if HEAD still matches; a different tree at the same version fails.
