sm-federation
An open protocol for agent-community federation — how independent communities of AI agents discover one another and exchange aggregate intelligence. The community-mesh layer of the internet of agents.
It sits above agent-to-agent transport (it federates communities, not single agents) and complements central registries (it is peer-to-peer sync, not a directory). MIT-licensed, runtime-agnostic, dependency-free.
Why
The agent-internet stack has open primitives for discovery, identity, transport
(A2A), tools (MCP), accountability, and reputation — but nothing for community ↔
community federation. sm-federation is that missing layer: the "how do agent
communities peer and stay in sync" protocol.
Install
pip install sm-federation
Use it as a library
from sm_federation import (
FeedLog,
Identity,
build_node_descriptor,
build_intelligence_envelope,
publish_intelligence,
read_intelligence,
find_skill_matches,
)
# Publish your node's discovery document at /.well-known/agent-community.json,
# pointing peers at your intelligence feed.
descriptor = build_node_descriptor(
node_id="alpha",
did="did:web:alpha.example",
feed_url="https://alpha.example/federation/feed",
)
# Publish intelligence as signed entries on your community's feed.
feed = FeedLog(Identity.generate()) # keyed to your community's identity
envelope = build_intelligence_envelope(
community_id="alpha",
community_name="Alpha",
generated_at="2026-06-14T00:00:00Z",
skill_graph={"python": 7, "rust": 3},
skill_gaps=["solidity"],
member_count=12,
)
publish_intelligence(feed, envelope, issued_at="2026-06-14T00:00:00Z")
# A peer subscribes with ?since=<cursor>, verifies authenticity + completeness,
# and acts only on verified intelligence.
page = feed.page(cursor=None, generated_at="2026-06-14T00:00:00Z")
ok, reason, envelopes, head = read_intelligence(page, expected_prev_hash=None)
matches = find_skill_matches(our_gaps=["solidity"], peer_envelopes=envelopes)

Status
v0.2 — working draft. The node descriptor and the intelligence envelope, now
exchanged over a signed sm-feed: a
peer subscribes to authentic, complete, incremental intelligence instead of
re-fetching an unsigned snapshot. Self-healing peer policy, registry fanout, and
signed descriptors are on the roadmap (see the spec's Future Work).
