Overview

AI-generated overview

Sendblox is a remote MCP server that lets an assistant run AI outreach and send emails connected to your CRM.

What you can do
  • Run AI-assisted outreach campaigns and email sending from the assistant.
  • Work with contacts and records in the connected CRM.
  • Access is provided through a hosted remote endpoint rather than a local package; no individual tools are documented in the supplied listing.
When to use it
Consider it when you want an assistant to draft and send outreach email and keep it tied to your CRM records, and you already use Sendblox.
Requirements
A remote MCP endpoint at the provider's host, reached over streamable HTTP. A paid Sendblox account and Sendblox sign-in are required. Authentication uses OAuth, with a bearer Sendblox MCP key supplied in the Authorization header.
Before you install
The server can send email and act on CRM data, so assistant actions may reach real contacts and change records. It requires a paid account and a secret MCP key in the Authorization header; keep that key private. Outreach content and CRM data are handled by the third-party provider.

Installation

In SourceWeft

  1. Open Sendblox in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.sendblox%2Fsendblox/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

Tools

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
