## Description
Structured aquarium, marine, terrarium and paludarium data for AI agents.

## Claude Desktop Quick Installation
Heuristic fallback — verify the package name and runner against the repository README before running it. Uses `npx` (confidence: low):

```json
"mcpServers": {
  "atlarium-habitat-database-mcp": {
    "command": "npx",
    "args": ["-y","atlarium-habitat-database-mcp"]
  }

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

| Surface | Value |
| --- | --- |
| MCP endpoint | `https://mcp.atlarium.bio/mcp` |
| MCP version | `2.0.0` |
| Transport | Streamable HTTP |
| Authentication | none |
| Tool surface | 39 public read-only tools |
| Prompts | 9 guided public prompts |
| Apps widget | `ui://widget/habitat-explorer.v3.html` |
| Server card | `https://mcp.atlarium.bio/.well-known/mcp/server-card.json` |
| Human docs | `https://atlarium.bio/mcp` |
| Official MCP Registry | `bio.atlarium/habitat-database` |

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

## What You Can Build

| Use case | Public tools |
| --- | --- |
| Species research | Search fish, aquatic animals and plants, then retrieve localized structured profiles. |
| Tank compatibility | Compare species against tank size, pH, hardness and temperature constraints. |
| Diagnostic triage | Search algae, aquatic diseases, plant problems and treatment references from public profiles. |
| Product selection | Explore product categories, brands, equipment and fertilizers. |
| Fertilization support | Search dosing regimes, calculate product doses, nutrient gaps and weekly totals. |
| Aquarium calculators | Estimate tank volume, weight, water changes, water chemistry, unit conversions and equipment needs. |
| Habitat planning | Generate a complete advisory tank plan with species, plants, products, warnings, motivations and related guides. |
| Guide retrieval | Search 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:

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

Claude Code remote HTTP example:

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

Smoke check the live endpoint:

```bash
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 host | Setup |
| --- | --- |
| OpenAI Agents SDK | See `examples/openai-agents-python` for a Python agent that connects to the remote Streamable HTTP endpoint. |
| Claude Code | Run `claude mcp add --transport http atlarium https://mcp.atlarium.bio/mcp`, then ask Claude to use Atlarium. |
| Cursor | Copy `examples/cursor/mcp.json` into your Cursor MCP config and reload Cursor. |
| Windsurf | Copy `examples/windsurf/mcp_config.json` into Windsurf MCP settings and refresh Cascade MCP servers. |
| VS Code | Copy `examples/vscode/mcp.json`; VS Code uses `type: "http"` for remote MCP servers. |
| Antigravity | Use `examples/antigravity/mcp.json` only in builds that support remote MCP servers. |
| Generic Streamable HTTP | Use the JSON-RPC examples in `examples/generic-streamable-http`. |
| ChatGPT Apps | Not approved on 2026-07-02; fixes are deployed and the package is ready for dashboard resubmission with the Habitat Explorer widget. Use `examples/chatgpt-apps` and `docs/chatgpt-review-remediation.md` for review notes, smoke prompts and screenshot checklist. Public approval is not claimed. |

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:

| Field | Value |
| --- | --- |
| Resource URI | `ui://widget/habitat-explorer.v3.html` |
| MIME type | `text/html;profile=mcp-app` |
| Widget | `Atlarium Habitat Explorer` |
| Widget domain | `https://mcp.atlarium.bio` |
| Output mode | Plain 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`.
For resubmission, replace the uploaded images with real ChatGPT web/mobile
screenshots that include the host UI. The ChatGPT App is not approved; do not
describe it as approved or publicly available until OpenAI accepts it.

`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.

## Configuration

- `MCP_PUBLIC_BASE_URL`: public base URL, production default `https://mcp.atlarium.bio`.
- `ATLARIUM_API_BASE_URL`: public read-only Atlarium API base URL.
- `MCP_ALLOWED_HOSTS`: comma-separated host allowlist used for DNS rebinding protection.
- `MCP_TRUST_PROXY`: Express proxy trust setting; default `1` assumes one trusted reverse proxy in production.
- `ATLARIUM_API_TIMEOUT_MS`: upstream public API timeout in milliseconds.
- `ATLARIUM_API_RESPONSE_MAX_BYTES`: maximum upstream JSON response size.
- `OPENAI_APPS_CHALLENGE_TOKEN`: public OpenAI Apps domain verification token served from `/.well-known/openai-apps-challenge`.

Production deployments must run behind a TLS-terminating reverse proxy or
Ingress that overwrites `X-Forwarded-For`, `X-Forwarded-Host` and
`X-Forwarded-Proto` before traffic reaches this server.

## Quality Gate

```bash
pnpm lint
pnpm typecheck
pnpm test
pnpm build
pnpm audit:prod
docker build -t atlarium-mcp:local .
```

With a local server running:

```bash
pnpm mcp:conformance
```

With production DNS and TLS live:

```bash
pnpm mcp:monitor:public
pnpm directories:submit -- --check
pnpm mcp:validate:public
pnpm mcp:conformance:public
```
