For AI assistants

Use Snake Finder in ChatGPT, Claude and other AI assistants

Snake Finder runs a free MCP (Model Context Protocol) server. Connect it to your assistant and it can answer questions about the snakes near you from the same verified records as this site, with a link back to the page for every answer. No account, no API key.

Server URL

Streamable HTTP, read-only, no authentication:

https://snakefinder.com/mcp

The four tools

find_snakes

The snakes recorded in a U.S. county, U.S. state, Canadian province or division, or any country, venomous species first. The same lists as our place pages.

Try: “What venomous snakes live in Travis County, Texas?”

get_snake

One species by common or scientific name: venom status, identification marks, look-alikes and how to tell them apart, habitat, and what to do if bitten.

Try: “Is a hognose snake venomous?”

compare_snakes

How to tell two snakes apart, with a quick field tell and feature-by-feature differences where we have a written comparison.

Try: “How do I tell a copperhead from a corn snake?”

snake_season

When snakes are active in a U.S. state, Canadian province or country, month by month, from verified sightings.

Try: “When is snake season in Arizona?”

Add it to Claude

In Claude, open Settings, then Connectors, and choose Add custom connector.
Name it Snake Finder and paste the server URL https://snakefinder.com/mcp. Leave the authentication settings empty.
Turn the connector on in a chat from the tools menu, then ask a question.

In Claude Code: claude mcp add --transport http snakefinder https://snakefinder.com/mcp

Add it to ChatGPT

In ChatGPT, open Settings, then Apps and Connectors, then Advanced settings, and turn on Developer mode.
Create a new connector, name it Snake Finder, paste https://snakefinder.com/mcp as the server URL and choose no authentication.
In a new chat, pick Snake Finder from the tools menu and ask a question.

Other MCP clients

Cursor, VS Code, Windsurf and most other clients that support remote servers take a config like this:

{
  "mcpServers": {
    "snakefinder": {
      "url": "https://snakefinder.com/mcp"
    }
  }
}

Good to know

Species lists and counts match our place pages and are built with the method on our methodology page. Records are never complete: a species missing from a list can still turn up.

Answers are for identification awareness and education, not medical advice, and an assistant cannot confirm an identification from a description or photo. Keep your distance from any snake you are unsure of. Anyone bitten should get emergency care: in the U.S., call 911 or Poison Control at 1-800-222-1222.
