zainar-halo-agent-tools
FastMCP server exposing ZaiNar RF halo awareness to LLM agents and Claude Desktop.
Gives an agent the ability to ask "what's around robot amr-7 right now?" and get a live answer — entity types, 3D ranges (cm), closing speeds — sourced from ZaiNar's RF network, not from cameras or line-of-sight sensors.
Install
pip install zainar-halo-agent-tools
Run the MCP server
zainar-halo-mcp
Add to Claude Desktop (~/Library/Application Support/Claude/claude_desktop_config.json):
{
"mcpServers": {
"zainar-halo": { "command": "zainar-halo-mcp" }
}
}
Inspect interactively:
npx @modelcontextprotocol/inspector zainar-halo-mcp
Tools
| Tool | What it does |
|---|---|
get_halo(device_id) |
Rich egocentric halo — who's around this node, ranges, closing speeds |
set_halo_config(device_id, ...) |
Set safety perimeter and entity filters (operator-owned) |
query_near(device_id, radius_cm, entity_types) |
Ad-hoc proximity query, no persistent config change |
list_tracked_entities() |
All tracked entities with 3D positions and freshness |
list_zones() |
Active zones and entity counts |
get_zone_entities(zone) |
Raw TMI position list for a zone |
Resources
| URI | What it returns |
|---|---|
zainar://halo/{device_id} |
Live halo JSON for a node |
zainar://zone/{zone} |
TMI position list for a zone |
zainar://entities |
All tracked entities |
Demo vs. production
The out-of-the-box server uses DemoLocationService — a fixed set of 6
demo positions (warehouse scenario with AMR, forklift, human, drone).
In production, swap it for ZainarLocationService from the
zainar-location-service package, which connects to the kinesis-gw
WebSocket and maintains a live position queue. The tool signatures are
identical.
