What Sendraven MCP server does

According to its repository: “Email for AI agents: send email, read replies as threads, and reply in context, with per-key send limits and approvals. Remote at https://mcp.sendraven.ai/mcp (OAuth) or npx -y @sendraven/mcp with SENDRAVEN_API_KEY. Requires a SendRaven account.”

An MCP server gives an AI agent extra tools it calls during the conversation: the agent reads their description, decides to use them and gets the result back. Sendraven MCP server is listed under Messaging and email, a category of 107 servers in the directory, where it ranks #98 by stars.

Topics declared by the repository: ai-agents, email, email-api, transactional-email.

Installing and connecting Sendraven MCP server

Distribution modes declared in the official MCP registry:

  • npm package (Node.js, usually started with npx)
  • remote server (streamable-http): you connect to it by URL, with nothing to install locally

Like any MCP server, you declare it in your client's configuration (Claude Desktop, Claude Code, Cursor, VS Code, Codex…): a name, the command that starts it or its URL, and any environment variables. The client then starts it and lists its tools. Project language: TypeScript.

The registry lists one secret variable to provide (API key, access token). Keep them in the client's environment variables, never in a shared file or a repository.

Security: what to check

An MCP server runs code with the rights you give it, and the model reads its tool descriptions: a malicious or compromised server can hijack the agent. Read the code, or pick a maintained and widely used server, before connecting it.

Points found for Sendraven MCP server:

  • Secrets: the server acts with your credentials. Create a dedicated key with minimum rights and an expiry date.

Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.

Project activity and maintenance

Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
