nmp-protocol 1.1.0

NMP (NeuroMessage Protocol) — Open communication protocol for multi-agent systems with behavioral modulation signals.

NMP — NeuroMessage Protocol

Open communication protocol for multi-agent AI systems with behavioral modulation.

NMP is to agent communication what HTTP is to web communication — but with built-in behavioral signals. While MCP handles tool access and A2A handles agent coordination, NMP carries intention, modulation, and accountability alongside data.

Quick Start

pip install nmp-protocol

from nmp import create_message, TrustLevel, validate_message

# Create an NMP message with behavioral signals
msg = create_message(
    from_agent="router",
    to_agent="legal-analyzer",
    content="Analyze this contract for risk clauses",
    trust=TrustLevel.VERIFIED,
)

# Modulate behavioral signals
msg.signals.urgency = 0.7      # Time-critical
msg.signals.quality = 0.9      # High analysis depth needed
msg.signals.inhibition = 0.0   # No blocking needed

# Validate
errors = validate_message(msg)
assert not errors

# Serialize
json_str = msg.to_json()

6 Behavioral Signals

Signal	Range	Biological Analog	Purpose
urgency	[0, 1]	Noradrenaline	Processing speed (Yerkes-Dodson curve)
quality	[0, 1]	Serotonin	Analysis depth
inhibition	[0, 1]	GABA	Blocking / pausing
activation	[0, 1]	Glutamate	Processing intensity
focus	[0, 1]	Acetylcholine	Context narrowing
reward	[-0.5, 1]	Dopamine	Feedback signal

Trust Levels

Trust can only decrease through a pipeline: min(current_trust, source_trust)

Level	Value	Meaning
HOSTILE	0	Known malicious source
UNTRUSTED	1	Unknown / unverified
VERIFIED	2	Authenticated but not fully trusted
TRUSTED	3	Fully trusted internal agent
