Botany MCP

Remote MCP server for authoritative plant information, starting with the public VicFlora GraphQL API.

What It Exposes

• search_plants - search VicFlora taxon concepts by scientific or common name.

• get_plant_profile - fetch a VicFlora taxon profile by concept ID or exact-ish name.

• find_plants_near_point - fetch VicFlora occurrence context near a coordinate.

• lookup_botanical_terms - look up botanical glossary terms from VicFlora.

The server is read-only. Tool responses include provider/source metadata and retrieval timestamps so model answers can stay grounded. Plant profile image URLs are served through this MCP's /images/vicflora proxy so browser clients can render VicFlora CDN images without CORS failures. Original CDN URLs are retained as thumbnailSourceUrl and previewSourceUrl.

Quick Start

npm install
npm run dev

The local server defaults to no auth at http://localhost:3000/mcp. When NODE_ENV=production, auth is required by default unless AUTH_REQUIRED=false is set explicitly.

Set HOST=0.0.0.0 on hosted platforms that require binding on all interfaces. On Railway, PUBLIC_BASE_URL can be omitted when RAILWAY_PUBLIC_DOMAIN is present; the server will derive https://<RAILWAY_PUBLIC_DOMAIN>. The image proxy defaults to VicFlora hosts only; override IMAGE_PROXY_ALLOWED_HOSTS with a comma-separated host list if VicFlora changes image CDNs.

curl http://localhost:3000/healthz
curl http://localhost:3000/.well-known/oauth-protected-resource

Auth

Local development defaults to no auth. For hosted personal use, enable a static bearer token:

NODE_ENV=production
BOTANY_MCP_TOKEN=generate-a-long-random-token
PUBLIC_BASE_URL=https://your-public-botany-mcp-origin # optional on Railway

When auth is enabled, every /mcp request must include:

Authorization: Bearer <BOTANY_MCP_TOKEN>

The token protects access to the MCP endpoint. Keep it secret, and rotate it if it is exposed.

For clients that require OAuth client credentials, such as Claude custom connectors, configure a built-in OAuth client:

NODE_ENV=production
OAUTH_CLIENT_ID=botany-mcp
OAUTH_CLIENT_SECRET=generate-another-long-random-secret
PUBLIC_BASE_URL=https://your-public-botany-mcp-origin # optional on Railway

Then enter the same OAUTH_CLIENT_ID and OAUTH_CLIENT_SECRET in the client. The server exposes OAuth discovery at /.well-known/oauth-authorization-server and issues short-lived bearer access tokens from /oauth/token.
