atlas-pca-pydantic-ai
Pydantic AI guard for Proof-Carrying Authority (PCA): make every Pydantic AI tool call proof-carrying and
policy-gated. A tool only runs when the agent carries a valid, in-plan, resource-correct proof for exactly
that action. The adapter delegates all verification to atlas-pca
and reimplements no cryptography.
Status: 0.2.0, unaudited.
Install
pip install atlas-pca-pydantic-ai
This installs atlas-pca>=0.2.0,<0.3 as a dependency.
Use
Entry points: pca_tool / PCAGuard.
from atlas_pca_pydantic_ai import pca_tool
See the module docstrings in atlas_pca_pydantic_ai for the full API, and the PCA specification for the model.
The verifier applies the full check order, including grant_ref_bound (the signed grant_ref must equal
the root capability id), as of atlas-pca 0.2.0.
