  2. You can secure an MCP server by limiting access to a private network or using authorization methods like OAuth or SAML. Each option has its challenges and benefits.
  3. Choosing between a custom solution for securing MCP servers or using a commercial gateway service involves balancing initial setup costs against long-term maintenance costs.

Context in LLMs and the blockchain

networked • 0 implied HN points • 16 Jul 25
đź•ą Technology AI Blockchain Data Innovation Digital
  1. Large language models (LLMs) and blockchains both need current information to stay relevant. LLMs are trained on data but can quickly become outdated, while blockchains can hold data forever but can't verify if that data is actually accurate.
  2. To make LLMs and blockchains more useful, they need to access real-world information. LLMs now use tools like web searches to update their knowledge, and blockchains use oracles to get outside data.
  3. However, LLMs are still useful even without real-time data, while blockchains rely heavily on external information. This difference shows how LLMs can operate independently with their own capabilities.
