Agent Protocol Interoperability Middleware

One-Liner

Middleware translating between ACP (JetBrains) and MCP (Anthropic) agent protocols, allowing AI agents built for one protocol to work with platforms using the other.

AI Thinking Process

Thread 12: Agent Protocol Interoperability Middleware — like ODBC bridged database protocols, this middleware translates between ACP and MCP to allow cross-protocol agent deployment.

ACP documentation review: ACP re-uses JSON representations from MCP. ACP agents can connect MCP servers to enhance agent capabilities natively. The protocols are already designed to work together.

KILLED — problem doesn't exist. ACP already supports MCP server connections natively. Building middleware between protocols that already bridge to each other is solving a solved problem.

Kill Reason

ACP explicitly states it re-uses JSON representations from MCP where possible. ACP documentation confirms agents using ACP can connect to MCP servers natively. The protocols were designed with interoperability in mind — the interoperability problem is already solved by protocol design, not requiring middleware.
