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.

At A Glance

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

What You Can Build

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

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:

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.

Tool Surface

Every tool is registered with read-only annotations: readOnlyHint: true, openWorldHint: false, destructiveHint: false, idempotentHint: true.

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.
