MCP servers offer agents read-only access or true ownership

The MCP (Machine Computation Protocol) server is becoming a standard feature for data tools, but a critical distinction exists in its implementation. Some MCP servers merely provide agents with read-only access to existing applications or data, limiting their utility to conversational queries. Others, however, offer agents ownership over infrastructure, allowing them to provision databases, write data, and persist information beyond a single interaction, thus enabling true autonomous agent capabilities. AI

IMPACT Distinguishes between agent-accessible data interfaces, highlighting the need for persistence to enable true autonomous agent functionality.

    Every data tool shipped an MCP server this year. Your agent still can't build on most of them.
