ProtoMap

Map gRPC services and Protobuf dependencies so developers and coding agents can trace changes.

About this product

ProtoMap scans code that uses gRPC and Protobuf and builds a graph of services, messages and their dependencies. Developers can inspect that map in the product, and coding agents can query it through MCP. The clearest use is investigating which callers might need attention before you change a service or a message field.

Start with one field whose callers your team knows. Compare the graph’s answer with the source locations and integration tests. Repeat after scanning another repository that calls the same service. This makes it easier to see where your scan scope leaves gaps before you ask an agent to plan a change across repositories.

The quickstart describes a self-hosted trial using Docker and PostgreSQL. The public site offers a demo for enterprise evaluation. Verify language coverage and the deployment requirements against the repositories you want to scan.
