mcp-mesh-core 2.5.0

Rust core runtime for MCP Mesh agents

MCP Mesh Core

Rust core runtime for MCP Mesh agents. This library handles:

• Agent startup and registration
• Heartbeat loop (fast HEAD + conditional POST)
• Topology management and change detection
• Event streaming to language SDKs

Building

# Install maturin
pip install maturin

# Build and install in development mode
maturin develop

# Build release wheel
maturin build --release

Usage from Python

from mcp_mesh_core import AgentSpec, start_agent

# Create agent specification
spec = AgentSpec(
    name="my-agent",
    version="1.0.0",
    registry_url="http://localhost:8100",
    http_port=9000,
    capabilities=[...],
    dependencies=[...],
)

# Start agent (returns handle)
handle = start_agent(spec)

# Listen for topology events
async def event_loop():
    while True:
        event = await handle.next_event()
        print(f"Event: {event.event_type}")
