Raven MCP Server
Odin's ravens brought back knowledge of the world - Raven brings back design intelligence. Its 40 documented tools cover audit, system, content, design.
People connecting coding agent tools to Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.

before you install - you'll need
The README does not document required environment variables for a basic install.
Claude Code
claude mcp add rhinocap-raven-mcp --transport http https://mcp.ravenmcp.ai/api/mcp Claude Desktop / Cursor / VS Code - add to config

} Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Security posture
What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.
runs as local process (stdio) - runs on your machine with your user's permissions · remote - your agent's requests go to mcp.ravenmcp.ai
endpoint auth accepted our unauthenticated MCP initialize - no credentials needed to connect
license Apache-2.0 - declared in the repository
npm package raven-mcp - unscoped; check the name against the project README before installing
registry vendor namespace ai.ravenmcp - domain-verified with the official MCP registry
03 · What Raven can do
Prose above is summarized from the project's README and registry record - no invented capabilities.
What you can build
With this server connected, an agent can get design principles relevant to a UI context, get proven patterns for a specific UI type, get business/monetization strategies, and search across all principles, patterns, and strategies.
