Tool Provisioning in MCP Servers: Controlling AI Agent Access in Production

MCP servers facilitate tool discovery and invocation for agents, but challenges arise when these servers are shared across multiple teams and environments, leading to issues in access control, credential management, and auditability. The core problem lies in unrestricted tool access, where agents can inadvertently access tools beyond their scope, resulting in over-permissioning and compliance risks. Effective governance requires a two-level tool provisioning model, with organization-level provisions controlling overall access and workspace-level provisions managing access within teams. This model ensures that only relevant tools are accessible to specific workspaces, thus maintaining security and compliance. Portkey's MCP gateway offers a centralized solution by managing tool provisioning, access control, and runtime governance at a gateway layer, integrating role-based access, authentication, and audit logs to maintain a secure and scalable infrastructure. This centralized approach prevents access sprawl and enhances traceability, crucial for maintaining trust and compliance across shared production environments.
