# Sender MCP MCP Server > **Sender MCP MCP Server** is a hosted, multitenant Model Context Protocol (MCP) server run by **MewCP** (https://mewcp.com), giving AI agents managed access to Sender MCP. > > MewCP takes care of all MCP infrastructure for you — credential storage, OAuth flows, > token refresh, and production-grade auto-scaling — so your AI agents can connect to > third-party services and run freely without you managing any MCP server yourself. > > Server page: https://mewcp.com/mcp/sender-mcp > MewCP docs: https://docs.mewcp.com > All servers: https://mewcp.com/servers (JSON: https://mewcp.com/api/servers) > About MewCP: https://mewcp.com/llms.txt --- ## About Sender is an email marketing platform built to help you create, automate, and send emails that people want to read – without complicated setup or high costs. --- ## Details - Server ID: `sender-mcp` - Version: 1.0.0 - Tools: 43 - Authentication: OAuth, managed by MewCP - Transport: http --- ## Access The gateway URL below serves your **entire MewCP toolset**, not this server on its own. Pasting a config snippet is not enough — Sender MCP has to be in the toolset first. In order: 1. Add Sender MCP to your toolset at https://mewcp.com/mcp/sender-mcp 2. Connect your Sender MCP account (OAuth); MewCP stores the credential and attaches it to each call 3. Add the gateway URL to your client (see Connect below). It signs in with OAuth the first time it connects, so there is no key to copy. Once connected, an agent does **not** see this server's tools as top-level tools. It sees four meta-tools and reaches everything through them: - `search(query)` — find tools by keyword across the toolset - `get_schema(tools)` — full description and arguments for the tools you picked - `list_accounts(provider)` — only when one app has several connected accounts - `call_tool(server_maskedId, tool_name, args)` — execute So the list below is what `search` can return for this server, not a set of callable tool names on their own. --- ## Tools (43) Descriptions are truncated to 160 characters; call `get_schema` for the full text and the argument schema.
