Article series maps agent memory and tools from context windows to MCP

On October 3, 2026, the Chinese developer platform Juejin published an article titled "Agent Memory and Tools: From Context Window to MCP," the latest entry in a series. The piece frames memory and tools as the two capability foundations of an Agent, arguing that no matter which decision-making and planning mode an Agent adopts, it relies on both. The previous installment in the series covered four decision-making and planning modes for Agents.

The article also traces an evolution path from the context window to MCP. Neither the summary nor the available excerpt names the individual stages, version numbers, or technical details along that path. A heading quoted from the excerpt states that memory and tools determine the capability boundary of an Agent, and the memory section is described as letting an Agent remember the past, accumulate experience, and maintain some form of continuity. The excerpt cuts off at that point, so the full explanation is not available.

As things stand, the record consists of a single Juejin post dated October 3, 2026, which positions memory and tools as the capability foundations of an Agent and uses the move from the context window to MCP as its organizing thread, while noting that an earlier piece in the series discussed four decision-making and planning modes. The report does not name any companies, product versions, or benchmark figures, and no other source has responded to or added to the article's content.
