Apizr

An open-source capability compiler for Python codebases.

Understand what existing Python code can expose before connecting it to an API or a tool client. Scan a codebase, inspect its capability graph, expose eligible functions through REST or MCP, and execute trusted code under explicit policies.

Discover

apizr scan . inventories Python files without importing or executing them. Scan your repository.

Understand

apizr graph . reports statically known relationships. apizr inspect example.py explains individual contracts; apizr readiness . assesses repository exposure evidence under a policy. Unknown evidence remains unknown. Understand the architecture.

Expose

Generate REST and MCP interfaces from the same eligible contracts. Start with a small typed function; no Docker is required for discovery or generation. Generate REST or generate MCP.

Govern

Choose direct execution or an explicit local-process/OCI policy. Static READY is not a safety guarantee. Local processes do not isolate filesystem/network access; OCI containers are not VMs. Execution remains experimental and requires trusted source and infrastructure. Understand execution boundaries.

Existing notebook workflows

Scripts and notebooks remain supported for inspection and generation. The Legacy generation pipeline is retained. See compatibility notes for supported environments and output behavior.
