About
The arcade marketplace entry for arcadeai-labs/omnimcp packages OmniMCP—a single HTTP MCP server at https://omni.arcade.dev/mcp with dynamic tool discovery across 500+ everyday integrations including Slack, Gmail, GitHub, Google Calendar, Notion, Linear, and Dropbox. One Arcade OAuth sign-in covers the server; each app prompts once on first use without pasting API keys. The repo ships Cursor, Claude Code, Claude Desktop, and OpenCode client configs plus slash commands /arcade:do, /arcade:apps, and /arcade:tools, skills, subagents, and session-start hooks. Install via /plugin marketplace add arcadeai-labs/omnimcp and /plugin install arcade@arcade, or add the bare MCP URL to mcp.json. Reach for it when an agent must send Slack messages, create GitHub issues, read calendar events, or summarize Gmail from natural language inside the editor.
