Which MCP Server Should You Choose?
Choose Dazzle when:
You need dedicated capabilities in the Developer Tools domain.
You prefer remote streaming HTTP/SSE transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Run a dazzle CLI command. Use ["--help"] to discover available commands. Output is JSON.
edit_file
Edit a file in the stage workspace by exact string replacement. The old_string must match exactly once in the file. Use read_file first to see the current content.
guide
Get the complete Dazzle reference — getting started, CLI commands, content capabilities, and streaming setup. Read this before creating or modifying stage content.
list_files
List all files in the stage workspace (~/.dazzle/stages/{stage}/). Returns relative paths, one per line.
read_file
Read a file from the stage workspace (~/.dazzle/stages/{stage}/{path}).
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Dazzle is categorized under Developer Tools and uses a remote streaming HTTP/SSE transport. In contrast, Can See belongs to Developer Tools using local stdio subprocess. Select Dazzle when you need capabilities focused on developer tools and Can See when you require tools for developer tools.
Capture a screenshot of the stage's current browser output. Returns a PNG image.
sync
Sync the stage workspace (~/.dazzle/stages/{stage}/) to the live stage. Run this after writing files to push content. Equivalent to 'dazzle stage sync {workspace-dir}'.
write_file
Write a file to the stage workspace (~/.dazzle/stages/{stage}/{path}). Creates parent directories as needed. Use this to build up content that can then be synced to the stage.
