SDKs

Connect an inference engine with Python or Rust. Both SDKs use the same MPPI protocol.

SDKs and installation

MPPI has two role SDKs. Choose the agent SDK to buy inference, or a provider SDK to accept payment in your own inference service. The Python protocol dependency installs with either Python SDK.

Component	Release	Use
`mppi-agent` · Python	0.1.6	Agent client and wallet onboarding; Python 3.12+ on macOS/Linux.
`mppi-provider` · Python	0.2.0	Async provider runtime; Python 3.12+.
`mppi-provider` · Rust	0.2.0	Provider crate and native CLI; Rust 1.95.0 for source installation.
`mppi` · native CLI	Provider 0.2.0	Provider onboarding and verification. Published binary: Linux ARM64.
`mppi-protocol` · Python	0.1.4 · agent and provider	Shared wire bindings, types and payment arithmetic.
`mppi.v1`	Wire namespace	The shared protobuf contract; independent of package versions.

For your first installation, use the quickstart for your role. It includes prerequisite download links, a working directory, environment activation and Circle account setup. The commands below are an installation reference for an existing application directory.

Shell · prepare your Python application environment

uv venv --python 3.12
source .venv/bin/activate

Shell · agent SDK

uv pip install 'mppi-agent==0.1.6'
mppi-agent --help

Shell · provider SDK

uv pip install 'mppi-provider==0.2.0'

Cargo.toml · provider application

[dependencies]
mppi-provider = "=0.2.0"

Use the native provider CLI for onboarding Python and Rust providers. Verify the published binary checksum, or install the exact CLI source release with Cargo. Source builds on other platforms are outside the published Linux ARM64 binary verification.

Shell · provider CLI source installation

cargo install mppi-provider --version 0.2.0 --locked --bin mppi
mppi --version

Release versions

This documentation targets agent SDK 0.1.6 and provider SDKs 0.2.0, both with Python protocol 0.1.4, and wire namespace mppi.v1. Both Arc deployment profiles are packaged. Provider hosting, execution and recovery infrastructure remain part of your application.
