Documentation

Everything you need to integrate DayBy into your workflow.

MCP Server

New

Post your dev progress directly from Claude Code, Claude Desktop, or Cursor. Content is sanitized locally before anything leaves your machine. API keys, tokens, IPs, and SSH keys are stripped automatically.

1. Install

npm install -g @dayby/mcp-server

2. Get your API key

Go to Settings → API, enable API access, and create a key.

export DAYBY_API_KEY=dyb_your_token_here

3a. Claude Code (terminal)

Run this once to register the server globally:

claude mcp add dayby -- dayby-mcp

Or pass the key inline if not in your environment:

DAYBY_API_KEY=dyb_your_key claude mcp add dayby -- dayby-mcp

3b. Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{ "mcpServers": { "dayby": { "command": "dayby-mcp", "env": { "DAYBY_API_KEY": "dyb_your_key" } } } }

3c. Cursor

Edit ~/.cursor/mcp.json:

{ "mcpServers": { "dayby": { "command": "dayby-mcp", "env": { "DAYBY_API_KEY": "dyb_your_key" } } } }
