Do you still need Context7 MCP if the model browses docs itself?

Summary

The creator asks whether the Context7 MCP server is still needed now that GPT-6.1 Sol browses technical documentation on its own when it needs to. The point is about agent tooling: a model that can fetch docs itself may not need a separate docs-retrieval MCP.

Key points

• Context7 MCP is used to feed current technical documentation to coding agents.
• GPT-6.1 Sol can browse technical documentation by itself when needed.
• Built-in browsing may make a separate docs MCP unnecessary. Check this for your own workflow before adding extra MCP servers.
