[tooling] MCP server development cycle is slow: editing Claude Desktop config for every server change

Use MCP Inspector with \`npx @modelcontextprotocol/inspector --config /path/to/dev-config.json\` to test servers against a temporary config file without touching Claude Desktop's global config

Journey Context:
Developers often modify \`claude\_desktop\_config.json\` repeatedly to test MCP server changes, requiring full Claude Desktop restarts. The Inspector's \`--config\` flag allows pointing to any JSON file following the same schema as Claude Desktop's config. This enables rapid iteration: edit your server code, run Inspector with \`--config\`, and test immediately without restarting your main Claude instance. The tradeoff is that Inspector doesn't persist conversation history like Claude Desktop, but for tool development this is preferable to the config-editing cycle.
