Launch the desktop GUI with map visualization, file pickers, and all workflow views. Requires the gui feature.

cargo run --release --features gui --bin web-ui

The GUI includes all the same views as the TUI — Extract, Clean, Compile, Optimize, VRP — plus an interactive map canvas with zoom/pan, native file dialogs, and a Bounding Box Filter on the Optimize page to limit optimization to a sub-region of a large .rmp file.

3. Command-Line Interface (CLI)

Use rmpca <COMMAND> for scripts, agents, and batch processing. All commands support a --json flag for structured output.

# Discover resources
rmpca list maps --json
rmpca list routes --json

# Run a task via Agent (JSON payload)
rmpca agent --task task.json --json

# Multi-vehicle VRP
rmpca vrp -i map.rmp --vehicles 5 --algo savings --coordinates stops.csv --depot "40.71,-74.01" --output-dir routes/

# Single-vehicle CPP Optimization (Outputs GPX)

MCP Server

rmpca ships an MCP (Model Context Protocol) server that exposes the route optimization pipeline as tools for AI agents. Compatible with Claude Desktop, Claude Code, Cursor, Continue, and any MCP-compliant client.

Quick Start

Add to your MCP client config. The cargo run command handles building automatically — no separate build step needed.

Claude Desktop — edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):
```
{
  "mcpServers": {
    "rmpca": {
      "command": "cargo",
      "args": ["run", "--bin", "rmpca-mcp-server", "--release"],
      "cwd": "/path/to/v2rmp"
    }
  }
}
```
Claude Code — run in your project directory:
```
claude mcp add rmpca -- cargo run --bin rmpca-mcp-server --release
```
Cursor / Continue / other clients — add the same JSON to your client's MCP server config under mcpServers.
Restart your MCP client (or reload the server list).
Ask your AI agent to use the tools. The agent will discover all tools automatically.

Example Conversation

User:  Extract Overture data for Monaco, compile it, and optimize a sweeper route

Agent: [calls extract_overture with bbox {min_lon:7.409, min_lat:43.723, max_lon:7.439, max_lat:43.751}]
       → 2340 nodes, 3102 edges, 45.6 km → extract-output.geojson
       [calls compile with input="extract-output.geojson", output="monaco.rmp"]
       → 1500 nodes, 2100 edges, 12 KB
       [calls optimize with input="monaco.rmp", mode="cpp"]
       → 52.3 km total, 92% efficiency, 12ms

AI Agent Task Format

The agent command consumes a JSON payload, allowing agents to trigger complex workflows without manual flag management.

{
  "type": "optimize",
  "input": "manhattan.rmp",
  "output": "delivery_route.gpx",
  "num_vehicles": 1,
  "solver_id": "clarke_wright",
  "oneway": "respect",
  "left_penalty": 1.5,
  "depot": [40.7128, -74.0060]
}

Usage (TUI)

1. Extract Road Network

Navigate to Extract Data view
Set bounding box (format: min_lon,min_lat,max_lon,max_lat)
Toggle between OSM and Overture sources
Output: extract_YYYYMMDD_HHMMSS.geojson

2. Compile to Binary

Navigate to Compile Map view
Set input GeoJSON file path
Output: .rmp binary file

3. Browse & Optimize

Use Browse Cached Maps to select a compiled map
Configure turn penalties and depot in the Optimize Route view
Run optimization to generate a GPX/GeoJSON route

Bounding Box Filter

When working with large maps (e.g., a full city), you can restrict optimization to a smaller area instead of running CPP on the entire network. In the Optimize Route view (TUI or GUI), set a bounding box in min_lon,min_lat,max_lon,max_lat format. Only nodes and edges within that box are included in the optimization. This dramatically reduces solve time for large datasets.

The core function is also available programmatically:

use v2rmp::core::optimize::filter_bbox;
use v2rmp::core::geo_types::BBox;

let bbox = Some(BBox {
    min_lon: -73.6,
    min_lat: 45.5,
    max_lon: -73.5,
    max_lat: 45.6,
});
let (sub_nodes, sub_edges) = filter_bbox(
    &nodes,
    &edges,
    bbox
);

// Pass None to use the full map

Elevation & Fuel

Query DEM GeoTIFF files from the CLI or MCP server. Supported via GDAL — works with any GDAL-compatible raster format.

# DEM metadata
rmpca elevation --dem dem.tif info

# Single point query
rmpca elevation --dem dem.tif point --lon -73.58 --lat 45.50

# Batch point query from JSON file (or stdin)
echo '[[-73.58,45.50],[-73.57,45.51]]' | rmpca elevation --dem dem.tif points

# Route elevation profile
echo '[[-73.58,45.50],[-73.57,45.51],[-73.56,45.52]]' | rmpca elevation --dem dem.tif profile -s 100

# Bbox elevation statistics
rmpca elevation --dem dem.tif stats --bbox "-73.60,45.48,-73.55,45.52" --step 10

# Fuel consumption from a route (base consumption L/km)
echo '[[-73.58,45.50],[-73.57,45.51]]' | rmpca elevation --dem dem.tif fuel -s 100 --base-consumption 0.08

All subcommands support --json for machine-readable output. See the MCP server section above for the corresponding elevation_query, elevation_profile, elevation_stats, dem_info, and fuel_estimate tools.

VRP Coordinate Input

The VRP solver accepts a CSV file of coordinates as its primary input. This replaces the previous JSON waypoints format.

CSV Format

The file must have a header row. Required columns are lat and lon; label, demand, and type are optional.

Column	Required	Description
`lat`	✅	Latitude (WGS-84)
`lon`	✅	Longitude (WGS-84)
`label`		Human-readable name (auto-generated if omitted)
`demand`		Per-stop demand (default: 0 for depots, 1 for stops)
`type`		`depot` or `stop` (default: `stop`; first row becomes depot if no `type` column)

Example

lat,lon,label,demand,type
45.5017,-73.5673,Montreal Depot,0,depot
45.5032,-73.5701,Customer A,5,stop
45.5100,-73.5800,Customer B,3,stop
45.4980,-73.5750,Customer C,2,stop
45.5050,-73.5900,Customer D,4,stop

Minimal (just coordinates — first row is automatically treated as the depot):

lat,lon
45.5017,-73.5673
45.5032,-73.5701
45.5100,-73.5800
45.4980,-73.5750

Binary Format (.rmp)

The .rmp format is a compact binary representation optimized for graph traversals:

[4 bytes]  Magic "RMP1"
[4 bytes]  Node count (u32 LE)
[4 bytes]  Edge count (u32 LE)
[N * 16]   Nodes: lat(f64) + lon(f64)
[E * 17]   Edges: from(u32) + to(u32) + weight_m(f64) + oneway(u8)
[4 bytes]  CRC32 checksum

Library Usage

use v2rmp::core::{extract, compile, optimize, vrp};

// VRP Solver Example
let vrp_input = vrp::VRPSolverInput {
    stops: my_stops,
    vehicles: 3,
    ..Default::default()
};
let solver = vrp::get_solver("clarke-wright")?;
let output = solver.solve(&vrp_input).await?;
