MPLP Specification v1.0.0 (Frozen)

Authoritative definitions live in the Schemas (Source of Truth).
This site provides structured specification navigation, references, and evaluation guidance for MPLP v1.0.0 (Frozen).

Non-Goals: MPLP is not a framework, not a runtime, and not a platform.

Positioning Analogy (Non-Normative)

Often described as "The Agent OS Protocol" — a conceptual analogy for lifecycle governance. This does not imply an execution runtime, operating system, or vendor platform.

ProtocolGovernanceLicenseSchemasValidation Lab (External)

Governed by MPGC. The specification is frozen at v1.0.0 — no breaking changes permitted. Reference SDKs and Golden Flows enable protocol conformance without vendor certification. Governance processes and constitutional records are maintained in the Repository governance/ directory; this site provides pointers only.

Architecture »

The layered foundation. L1 Core (State), L2 Coordination (Governance), and L3 Execution (Semantics).

Modules »

Composable building blocks. Memory, Planning, Tools, and User Interaction standards.

Profiles »

Standardized agent capabilities. Define Role, Complexity, and Conformance levels.

Observability »

Full-stack visibility. Distributed Tracing, Event Bus specs, and Log Standards.

Tests »

Golden Flows and Conformance Suites define reproducible scenarios that generate evidence packs. Adjudication is provided externally by the Validation Lab.

SDK »

Build faster. Official libraries for TypeScript, Python, and Go.
