  "mcpServers": {
    "ollama": {
      "command": "npx",
      "args": [
        "-y",
        "ollama-mcp-server"

Gotchas

Claude Code stores MCP servers under an "mcpServers" object in ~/.claude.json. It also reads a project-scoped .mcp.json and supports adding servers from the command line with "claude mcp add". Each entry must declare either a "type" or a "command"; Claude Code refuses an entry that has neither. Remote servers connect natively over Streamable HTTP with OAuth.
