Fair meeting point discovery for AI agents with isochrone-based travel time fairness

Code source Documentation

Installation

Ajoutez ceci à la configuration MCP de votre client (Claude Desktop : claude_desktop_config.json ; Cursor : .cursor/mcp.json ; VS Code et les autres utilisent la même forme « mcpServers »).

NPM package rendezvous-mcp
Claude Code 
claude mcp add rendezvous-mcp -e 'VALHALLA_URL=<VALHALLA_URL>' -- npx -y rendezvous-mcp@1.1.3
Configuration JSON (Claude Desktop, Cursor, VS Code)

Fair meeting points for AI — isochrone-based fairness, not naive midpoints.

MCP server for AI-driven meeting point discovery. Give your AI the ability to answer "where should we meet?" using real travel times, venue availability, and fairness algorithms.

Works out of the box — free public routing, no API keys needed. Self-host Valhalla for unlimited queries, or use L402 Lightning credits for our hosted endpoint.

Tools

ToolDescription
score-venuesScore candidate venues by travel time fairness for 2–10 participants
search-venuesSearch for venues near a location using OpenStreetMap
get-isochroneGet a reachability polygon (everywhere reachable within N minutes)
get-directionsGet directions between two points with turn-by-turn steps
store-routing-credentialsStore L402 macaroon + preimage after Lightning payment

Quick start

Add to your MCP client config (Claude Code, Claude Desktop, Cursor, etc.):

{
  "mcpServers": {
    "rendezvous": {
      "command": "npx",
      "args": ["rendezvous-mcp"]
    }
  }
}

Then ask your AI: "Where's a fair place for Alice in London, Bob in Bristol, and Carol in Birmingham to meet for lunch?"

Remote (HTTP/SSE)

For ChatGPT, remote AI agents, or any client that connects over HTTP:

TRANSPORT=http npx rendezvous-mcp

Starts a Streamable HTTP server on port 3002 with the MCP endpoint at /mcp.

ChatGPT connector

In ChatGPT settings, add an MCP server with:

  • URL: http://your-host:3002/mcp
  • Transport: Streamable HTTP

Configuration

VariableDefaultDescription
TRANSPORTstdioTransport mode: stdio or http
PORT3002HTTP server port (HTTP mode only)
HOST0.0.0.0HTTP bind address (HTTP mode only)
VALHALLA_URLhttps://routing.trotters.ccRouting engine URL
OVERPASS_URLPublic endpointsVenue search API

Self-hosted routing

For unlimited queries with no rate limits, run your own Valhalla instance:

{
  "mcpServers": {
    "rendezvous": {
      "command": "npx",
      "args": ["rendezvous-mcp"],
      "env": {
        "VALHALLA_URL": "http://localhost:8002"
      }
    }
  }
}

How it works

  1. User asks "Where should we meet?"
  2. AI geocodes participant locations
  3. AI calls search-venues to find candidate venues near the area
  4. AI calls score-venues with participants + candidates — returns ranked results with travel times and fairness scores
  5. AI presents the fairest option with travel times for each person

For deeper analysis, the AI can use get-isochrone to visualise reachability and get-directions for turn-by-turn navigation.

L402 payments

The default routing endpoint (routing.trotters.cc) offers free requests. When the free tier is exhausted, tools return a payment_required response with a Lightning invoice. After payment, call store-routing-credentials to store the macaroon for the session.

Self-hosted Valhalla has no payment requirement.

Architecture

Thin MCP wrapper over rendezvous-kit — the open-source TypeScript library for isochrone intersection, venue search, and fairness scoring. Each tool is an extracted handler function (testable without MCP) plus a registration one-liner.
