How to install Sendraven MCP in Claude CodeAnthropic's agentic CLI

  1. Add the server

    bash
    claude mcp add sendraven -e 'SENDRAVEN_API_KEY=<SENDRAVEN_API_KEY>' -- npx -y @sendraven/mcp
  2. Fill in your credentials

    Replace <SENDRAVEN_API_KEY> with your real value. Keep secrets out of any config file you commit.

  3. Verify it's connected

    bash
    claude mcp list
  4. Sharing it with your team?

    Add `--scope project` to write it to .mcp.json in the repository root, which you can commit (with the secrets left as environment variables).

  5. Use it in a session

    Ask Claude to use the tools this server exposes (e.g. send_email, list_emails, get_email). It discovers them automatically.

  • get_email_preferencesWhat one person has chosen to receive. It shows whether someone who isn't getting a particular kind of email opted out of it — an opt-out looks identical to a delivery failure from the outside.
  • set_email_preferencesSet which topics a person receives, recording what they asked for — silently re-subscribing someone who opted out is what generates spam complaints. Every key must be an existing topic from list_topics: one unknown key refuses the whole cal

  • get_contactFetch one contact by id, with their audience memberships, custom properties and engagement dates.

  • list_segmentsList saved audience filters. A campaign created with a segment id, rather than a filter described inline, shares one definition that can be reused and counted.
  • list_tagsEvery tag in use in the workspace, with how many contacts carry each. Tags are free-form, so this is the only way to know what exists before applying one.
  • count_segmentHow many contacts a segment currently matches. A filter that matches nobody shows up here as 0, before any campaign is built around it or sent. Engagement windows and date conditions (e.g. attributes.trial_ends_at within_next_days 3) are me
  • get_email_metricsDelivery and engagement over a window. Open and click rates are over delivered, not sent — a low open rate with a high bounce rate is a deliverability problem, not an engagement one.
  • list_scheduled_emailsMessages queued to send later but not yet sent, newest first; cancel_scheduled_email cancels one. At most 100 per call; while has_more is true, next_cursor passed back as cursor returns the next page.
  • suppress_manyStop sending to many addresses at once — the path for importing another provider's unsubscribe list before a first campaign. Without it, everyone who already opted out there gets mailed again here. The defaults differ from add_suppression:
  • list_webhooksThe workspace's webhook endpoints: each with id, url, the events it receives and whether it is enabled. Read-only: endpoints are added and changed in the dashboard, because a tool that could point one at a new URL would let an agent route t
  • list_webhook_deliveriesRecent delivery attempts for a webhook endpoint: each with event, status, attempts, last_status_code, last_error and delivered_at (null until it succeeds). This is what tells 'we never sent it' from 'your endpoint returned 500'. Newest firs
  • list_broadcast_recipientsWho a campaign reached and what happened to each message, with the A/B variant when there is one. At most 200 per call; while has_more is true, next_cursor (a message id) passed back as cursor returns the next page.

Documentation

Full README

@sendraven/mcp

The SendRaven MCP server. Send email, read replies as threads, run campaigns and automations, and decide approvals, from any client that speaks the Model Context Protocol.

SendRaven is email infrastructure for AI agents. Agents use it over REST or MCP to run real email conversations: sending, reading replies as threads, and running campaigns and automations, within limits and approvals set on the API key. It is priced per email sent, never per contact.

Install

Claude Code, remote server, signs in with OAuth on first use:

bash
claude mcp add --transport http sendraven https://mcp.sendraven.ai/mcp

Cursor, Claude Desktop, and other clients with a JSON config:

json
{
  "mcpServers": {
    "sendraven": {
      "url": "https://mcp.sendraven.ai/mcp"
    }
  }
}

Any client, as a local process. Create an API key under Developers in the dashboard, then:

bash
claude mcp add sendraven -e SENDRAVEN_API_KEY=sk_live_… -- npx -y @sendraven/mcp
json
{
  "mcpServers": {
    "sendraven": {
      "command": "npx",
      "args": ["-y", "@sendraven/mcp"],
      "env": { "SENDRAVEN_API_KEY": "sk_live_…" }
    }
  }
}

Remote server with a key instead of OAuth, for an agent running unattended:

json
{
  "mcpServers": {
    "sendraven": {
      "url": "https://mcp.sendraven.ai/mcp",
      "headers": { "Authorization": "Bearer sk_live_…" }
    }
  }
}

Give an agent's key a daily send limit, a recipient allowlist, or an approval hold. The tools respect all three, campaigns included: a key with an approval hold or an allowlist cannot start a campaign, and a key with a daily limit can start one only if its recipients fit what is left of the day. See Limits for agents.
