Currently, MCP only talks to servers running on a local computer, but Alex Albert, head of Claude relations at Anthropic, said in a post on X that work is in progress to allow for remote servers with enterprise-grade authentication.
“An MCP server shares more than just data as well. In addition to resources (files, docs, data), they can expose tools (API integrations, actions) and prompts (templated interactions),” he added. “Security is built into the protocol — servers control their own resources, there’s no need to share API keys with LLM providers, and there are clear system boundaries.”
Anthropic said that developers can start building and testing MCP connectors today, and existing Claude for Work customers can test MCP servers connecting to internal systems and data sets. And, the company promised, “We’ll soon provide developer toolkits for deploying remote production MCP servers that can serve your entire Claude for Work organization.”
