Beyond Prompt-Based Planning: MCP-Native Graph Planning-based Biomedical Agent System

arXiv:2606.04494v1 Announce Type: new Abstract: Biomedical agents promise to automate complex biological workflows, yet current systems face two fundamental bottlenecks: bioinformatics tools are highly heterogeneous in interfaces and execution environments, while agent planning still relies on flat prompt-retrieved tool descriptions. As biomedical software ecosystems grow, this coupling between tool coverage and context size leads to tool confusion, unstable planning, and inefficient execution. We introduce BioManus, an MCP-native biomedical agent built on graph-scaffolded planning over struct

Why this matters
Why now

The proliferation of bioinformatics tools and the increasing complexity of biological research necessitate more robust and autonomous AI planning systems to overcome current limitations in prompt-based approaches.

Why it’s important

This breakthrough addresses fundamental bottlenecks in biomedical agent systems, paving the way for more efficient and reliable automation of complex biological workflows and drug discovery processes.

What changes

AI agents in synthetic biology will transition from constrained prompt-based planning to more flexible and stable graph-scaffolded planning, improving their ability to navigate heterogeneous tool environments.
