marketing-mcp-server

An early-stage MCP (Model Context Protocol) server for marketing analytics, built with Rust, Actix-web, and async-graphql.

Status: Very early work in progress / scaffolding. The server starts and the MCP + GraphQL endpoints are wired up, but most domain logic is not yet implemented.

Overview

marketing-mcp-server is a Rust service that exposes two APIs simultaneously:

• A GraphQL API (via async-graphql) for querying marketing metrics
• An MCP endpoint (via rmcp) at /api/v1/mcp, allowing AI assistants to call the server as a tool

The intended domain covers marketing analytics concepts such as CPA (Cost Per Acquisition), churn rate, and integrations with platforms like Salesforce, SAP, and Microsoft 365 — though these are currently stubs.
