Description from the maker (original English)
Fair meeting point discovery for AI agents with isochrone-based travel time fairness
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
The GitHub repo last changed –, and the latest version (1.1.3) reached the registry 7 months ago.

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.
| Tool | Description |
|---|---|
score-venues | Score candidate venues by travel time fairness for 2–10 participants |
search-venues | Search for venues near a location using OpenStreetMap |
get-isochrone | Get a reachability polygon (everywhere reachable within N minutes) |
get-directions | Get directions between two points with turn-by-turn steps |
store-routing-credentials | Store L402 macaroon + preimage after Lightning payment |
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?"*
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.
In ChatGPT settings, add an MCP server with:
http://your-host:3002/mcp| Variable | Default | Description |
|---|---|---|
TRANSPORT | stdio | Transport mode: stdio or http |
PORT | 3002 | HTTP server port (HTTP mode only) |
HOST | 0.0.0.0 | HTTP bind address (HTTP mode only) |
VALHALLA_URL | https://routing.trotters.cc | Routing engine URL |
OVERPASS_URL | Public endpoints | Venue search API |
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" } } } }
search-venues to find candidate venues near the areascore-venues with participants + candidates — returns ranked results with travel times and fairness scoresFor deeper analysis, the AI can use get-isochrone to visualise reachability and get-directions for turn-by-turn navigation.
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.
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.
