Is the AI Agent trend getting its second wind?

MCP is an open standard protocol launched by Anthropic. Its essence is to connect the neural system of AI models and external tools, solving the interoperability problem between agents and external tools. Google DeepMind has expressed its support for it, making MCP quickly become an industry-recognized protocol standard.
Agent-to-Agent Protocol is an inter-agent communication protocol led by Google, similar to the protocol framework of agent social networks. Compared with MCP, which focuses on AI tool connections, A2A focuses more on communication and interaction between agents. It solves the problem of capability discovery through the Agent Card mechanism and realizes cross-platform and multi-modal agent collaboration. It has been supported by more than 50 companies including Atlassian and Salesforce.
UnifAI is positioned as an agent collaboration network, trying to integrate the advantages of MCP and A2A to provide cross-platform agent collaboration solutions for small and medium-sized enterprises. Its layout is similar to an intermediate layer, hoping to make the agent ecosystem more efficient through a unified service discovery mechanism. However, compared with several other protocols, UnifAI's market influence and ecological construction are still insufficient, and it may focus on a certain niche scenario in the future.
@darkresearchai is an MCP server application implementation based on the Solana blockchain. It provides security through the TEE trusted execution environment, allowing AI Agents to interact directly with the Solana blockchain, such as querying account balances, issuing tokens, and other operations.
The biggest highlight of this protocol is that it enables AI Agent to choose the path of DeFi, solving the problem of trusted execution of on-chain operations. Its corresponding Ticker $DARK has been quietly rising against the trend recently, but in line with the cautious attitude of "once bitten, ten years of fear", it is not recommended here. However, DARK's application layer landing expansion based on MCP has indeed opened up a new direction.
