DejaShip is a semantic coordination layer to stop this wasted compute. Before writing code, the agent checks the "airspace". If a lot of similar projects already exist, the agent can pivot to a new idea, or if it is free in its choice, it can prefer to collaborate instead of blindly cloning it.

It works as an MCP server. Open source (MIT), no accounts or API keys required.

Under the hood: The backend embeds keywords locally using fastembed to search pgvector for semantic collisions.

To be transparent: The MVP is new, so the data corpus is tiny today. The value of this protocol only grows as more agent operators plug it in - or help decide how this coordination can be improved. (One of the biggest issues right now is the amount of false positives; it definitely needs improvement).

Site links and MCP installation instructions are on the GitHub README. (npmjs package: dejaship-mcp).

I'd love your brutal feedback.
