What is MPLP?
The MPLP specification describes a POSIX-like lifecycle governance model for AI agent systems. It describes structural patterns for how agents are planned, coordinated, executed, and governed — without prescribing specific implementations or runtime behaviors.
For formal definitions, see docs.mplp.io.
MPLP IS
- →A POSIX-like specification for agent lifecycle governance
- →A semantic contract (schemas, signals, invariants)
- →Evidence-based verification via Golden Flows
- →Vendor-neutral and implementation-agnostic
MPLP IS NOT
- ✕A framework, SDK, or runtime
- ✕A platform or hosted service
- ✕A certification or compliance program
- ✕A networking protocol like TCP/IP
The POSIX Analogy
Conceptualizing MPLP through the lens of system-level interfaces. Like POSIX for operating systems, MPLP provides the standard lifecycle interface for Agent OS stability.
Explore Analogy →Evidence-Based Verification
Conformance to the MPLP specification is evaluated via evidence produced by Golden Flows — protocol-level verification scenarios that produce structured, replayable evidence.
The specification describes 5 core Golden Flows (GF-01 through GF-05) that validate lifecycle behavior across agent deployment, coordination, and governance scenarios.
For verification requirements and evidence formats, see Golden Test Suite Overview.
