As answered by people managing StackMail and Reach MCP.
Reach MCP's answer:
The only LinkedIn MCP server built for AI agents and for LinkedIn account safety.
Reach MCP's answer:
Reach MCP is built by the Kanbox team, trusted by 2,000+ teams on LinkedIn. Customer names are kept private by default.
Reach MCP's answer:
AI and automation agencies and builders who give their AI agents LinkedIn access, often across several client accounts.
Reach MCP's answer:
Other tools added AI on top of LinkedIn automation; Reach MCP was built for agents from day one, with account safety enforced by the server, not left to the agent.
Reach MCP's answer:
We're the team behind Kanbox, a LinkedIn tool used by 2,000+ teams with 2 million messages sent. When AI agents arrived, our users wanted Claude and n8n to handle LinkedIn for them. But an agent with raw LinkedIn access doesn't know when to stop. It sends too much and repeats actions, which gets accounts restricted. So we built Reach MCP: everything we learned about keeping LinkedIn accounts safe, packaged as a server designed for agents.
Reach MCP's answer:
Backend: Python, FastAPI, PostgreSQL Frontend: React, TypeScript, Vite, Tailwind CSS Infrastructure: Google Cloud Run and Cloud SQL (EU, Belgium), Cloudflare Protocols: Model Context Protocol (Streamable HTTP), OAuth 2.1 with PKCE, REST/OpenAPI, signed webhooks Other: a Chrome extension to connect LinkedIn accounts, Stripe for billing
