Lizard MCP server

Lizard MCP

An MCP server that lets ChatGPT, Claude and other MCP clients deploy and manage apps on Lizard (lizard.build).

Connect it once, then ask your assistant to ship a service, read logs, set secrets, scale replicas or attach a domain — in plain words.

Connect a client

The server speaks Streamable HTTP at POST /mcp, and stdio for clients that spawn a local process instead (below). A hosted instance runs at:

https://employ-woman-g1q2.us-east-1.onlizard.com/mcp

Every request carries a bearer token. A client that speaks OAuth gets one itself — the server advertises where, so there is nothing to paste. Clients that only send headers use a liz_ API key instead:

lizard keys create my-mcp-key

The dashboard creates the same thing under Sandboxes → Get started → New API key. Either way the key is shown once.

Claude Code

claude mcp add --transport http lizard https://employ-woman-g1q2.us-east-1.onlizard.com/mcp

Claude Code runs the OAuth flow on first use. To skip it and use a key:

claude mcp add --transport http lizard https://employ-woman-g1q2.us-east-1.onlizard.com/mcp \
  --header "Authorization: Bearer liz_your_key"

Cursor and other clients configured by JSON

{
  "mcpServers": {
    "lizard": {
      "url": "https://employ-woman-g1q2.us-east-1.onlizard.com/mcp",
      "headers": { "Authorization": "Bearer liz_your_key" }
    }
  }
}

ChatGPT

ChatGPT connects to a URL and runs OAuth itself — no key to paste. It needs developer mode and a registered connection; see Publishing to Codex / ChatGPT below.

Against a local server

Run it as described in the next section, then use http://localhost:3000/mcp in place of the hosted URL.

Check the connection

curl -sS -X POST https://employ-woman-g1q2.us-east-1.onlizard.com/mcp \
  -H "Authorization: Bearer liz_your_key" \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Without a token the same call returns 401 and a WWW-Authenticate header pointing at the OAuth metadata. That is the server working, not failing.

Run it

npm install
npm run build
npm start

For development with reload:

npm run dev

Run it over stdio

npm start serves HTTP. To have a client spawn the server instead, point it at dist/stdio.js:

{
  "mcpServers": {
    "lizard": {
      "command": "node",
      "args": ["/path/to/lizard-mcp/dist/stdio.js"],
      "env": { "LIZARD_TOKEN": "liz_your_key" }
    }
  }
}

A spawned process has no browser to run OAuth in, so the token comes from the environment and binds the process to one user. Without it the server still starts and lists its tools — calling one then returns a message asking for a key.
