Raven

Raven is a remote MCP server: there is nothing to install. Its endpoint is https://mcp.ravenmcp.ai/api/mcp, served over Streamable HTTP. In an assistant that accepts remote MCP servers (often under a setting named connectors, integrations or tools), add a new server and give it this URL; in a client configured by file, add it as a remote (HTTP) server with the same URL.

No headers are declared in the registry entry. If the server needs you to sign in, a client that supports MCP authorization opens the service's own sign-in page when it first connects.

It can also run locally from a Node.js package published to the npm registry: raven-mcp version 2.6.0. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs Node.js; clients usually start it with npx — the usual command is npx -y raven-mcp@2.6.0.

In the mcpServers JSON format that many desktop and editor MCP clients read, the entry looks like this (placeholders in angle brackets):

{
  "mcpServers": {
    "raven-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "raven-mcp@2.6.0"
      ]
    }
  }
}
