01 · Install Variflight MCP

before you install - you'll need

Set VARIFLIGHT_API_KEY before connecting.

Claude Code

claude mcp add variflight-variflight-mcp -- npx -y @variflight-ai/variflight-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "variflight-variflight-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@variflight-ai/variflight-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license no standard license detected - usage rights unclear; check the repo before commercial use

npm package @variflight-ai/variflight-mcp - the @variflight-ai scope differs from the repo owner (variflight); confirm it's the project's official package

registry namespace io.github.variflight is GitHub-verified and matches the repo owner

The 3 tools it gives your agent

Extracted from the project's README - what variflight-mcp lets an agent do.

limit: - maximum number of results to return
offset: - number of results to skip; pass next_offset from the previous response to get the next page. Each page is a separate billed call.
detail: - "summary" returns only the core fields of each result; "full" (the default) returns every field
