PopNx MCP’s three pillars

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

Common questions

Is Atlarium Habitat Database MCP 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 (2.0.3) reached the registry 3 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?

Atlarium Habitat Database MCP

Public read-only MCP server for Atlarium habitat data, diagnostics, products, calculators and advisory planning.

MCP endpoint · Human docs · Server card · Technical docs · Client examples

Atlarium Habitat Database MCP gives AI agents structured access to public Atlarium data and advisory functions for aquariums, marine tanks, coldwater systems, terrariums, paludariums and vivariums. It exposes 39 public read-only tools for species, plants, products, guides, algae, diseases, plant problems, medicines, compatibility, fertilization, calculators and complete habitat planning without exposing Atlarium accounts, private workspaces, admin APIs or write operations.

https://atlarium.bio/mcp is documentation. The canonical Streamable HTTP MCP endpoint is https://mcp.atlarium.bio/mcp.

What You Can Build

Use casePublic tools
Species researchSearch fish, aquatic animals and plants, then retrieve localized structured profiles.
Tank compatibilityCompare species against tank size, pH, hardness and temperature constraints.
Diagnostic triageSearch algae, aquatic diseases, plant problems and treatment references from public profiles.
Product selectionExplore product categories, brands, equipment and fertilizers.
Fertilization supportSearch dosing regimes, calculate product doses, nutrient gaps and weekly totals.
Aquarium calculatorsEstimate tank volume, weight, water changes, water chemistry, unit conversions and equipment needs.
Habitat planningGenerate a complete advisory tank plan with species, plants, products, warnings, motivations and related guides.
Guide retrievalSearch and retrieve public Atlarium educational content.

All outputs are advisory. Compatibility checks, diagnostics, fertilization plans, equipment estimates, aquarium calculators and tank suggestions should be verified against real livestock, equipment, water chemistry, local regulations and husbandry constraints.

Quickstart

Use any MCP client that supports remote Streamable HTTP servers:

{

"mcpServers": { "atlarium": { "type": "streamable-http", "url": "https://mcp.atlarium.bio/mcp" } } }

Claude Code remote HTTP example:

claude mcp add --transport http atlarium https://mcp.atlarium.bio/mcp

Smoke check the live endpoint:

curl --fail --silent --show-error https://mcp.atlarium.bio/health

curl --fail --silent --show-error https://mcp.atlarium.bio/.well-known/mcp/server-card.json pnpm mcp:monitor:public

Client Setup

Client or hostSetup
OpenAI Agents SDKSee examples/openai-agents-python for a Python agent that connects to the remote Streamable HTTP endpoint.
Claude CodeRun claude mcp add --transport http atlarium https://mcp.atlarium.bio/mcp, then ask Claude to use Atlarium.
CursorUse the Add to Cursor deep link or the root mcp.json.
ClineAdd the hosted endpoint as a Streamable HTTP remote server; llms-install.md contains deterministic agent setup instructions.
WindsurfCopy examples/windsurf/mcp_config.json into Windsurf MCP settings and refresh Cascade MCP servers.
VS CodeCopy examples/vscode/mcp.json; VS Code uses type: "http" for remote MCP servers.
AntigravityUse examples/antigravity/mcp.json only in builds that support remote MCP servers.
Generic Streamable HTTPUse the JSON-RPC examples in examples/generic-streamable-http.
ChatGPT AppsThe existing app version 1.0.0 is approved in the OpenAI dashboard. The corrected 2.0.3 package was resubmitted on 2026-08-29 with taxonomy-stable tests and OpenAI Platform now shows Review. Use examples/chatgpt-apps and docs/chatgpt-review-remediation.md for review notes and smoke prompts.

These are compatibility notes, not vendor endorsements. Do not make vendor or directory support claims for ChatGPT, Claude, Cursor, Windsurf, VS Code, Antigravity or any directory unless that vendor has accepted the listing.

ChatGPT App And Widget

The server advertises a read-only MCP Apps / ChatGPT Apps widget resource for Apps-compatible hosts:

FieldValue
Resource URIui://widget/habitat-explorer.v4.html
MIME typetext/html;profile=mcp-app
WidgetAtlarium Habitat Explorer
Widget domainhttps://mcp.atlarium.bio
Output modePlain JSON text plus structuredContent

The widget renders public habitat results, profiles, diagnostic summaries, product results, calculator output, compatibility summaries, fertilization plans and habitat suggestions. It does not add write access and does not expose workspace, auth, admin, journal, schedule or measurement data.

Widget-only development screenshots and a short demo recording are checked in under docs/assets/chatgpt-screenshots/ and docs/assets/chatgpt-app-demo.mp4. Real host-level web and responsive 390x844 captures are stored under docs/assets/chatgpt-screenshots/real-host/; native iOS/Android recording is still required for the final review package. The v4 / 2.0.3 candidate is live at the MCP endpoint but is not yet approved as the new ChatGPT App version; do not describe that app submission as approved until OpenAI accepts it. The existing dashboard app version 1.0.0 is approved.

Guided Prompts

The server advertises guided prompts for species search, compatibility, habitat planning, algae, diseases, plant problems, product selection, fertilization and tank calculations. Prompts guide clients toward the same public read-only tool surface; they do not add new capabilities or write access.

Tool Call Examples

Each example shows the MCP tool name and a minimal valid JSON input. Generic MCP clients receive plain JSON text; Apps-compatible hosts can also use structuredContent.
