Centralized MCP Gateway Resolves Enterprise Authentication Crisis
A recent study published on arXiv (2608.10760) details the implementation of a centralized Model Context Protocol (MCP) gateway aimed at resolving the authentication and governance challenges that have emerged due to the swift adoption of MCP in large enterprises. In just one year, organizations transitioned from having no MCP servers to establishing numerous internal servers, each managing authentication in varying ways—some lacking authentication, others utilizing API keys, and some employing full OAuth—resulting in a disjointed system. The proposed gateway acts as a unified layer for aggregation, governance, and authentication for all downstream MCP servers. The paper outlines four contributions based on practical experience, including a two-axis authentication model and solutions to identity delegation and the user/non-user persona dilemma. This work emphasizes the real-world difficulties of scaling MCP in corporate settings.
Key facts
- The paper is from arXiv, identifier 2608.10760.
- It is a cross announcement type.
- The Model Context Protocol (MCP) has become the de-facto interface for connecting LLM agents to enterprise tools.
- Adoption has been explosive: within a year, large organizations went from zero to dozens of internally built MCP servers.
- Each team implemented authentication independently, leading to a fragmented landscape.
- The proposed solution is a centralized MCP gateway that provides aggregation, governance, and authentication.
- The paper makes four contributions: a two-axis authentication model, identity delegation, and addressing the user/non-user persona problem.
- The work is based on production experience in an industry deployment.
