atlas-pca-fastmcp

FastMCP guard for Proof-Carrying Authority (PCA): make every FastMCP 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-fastmcp

This installs atlas-pca>=0.2.0,<0.3 as a dependency.

Use

Entry points: PCAMiddleware.

from atlas_pca_fastmcp import PCAMiddleware

See the module docstrings in atlas_pca_fastmcp 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.
