Pumperly-MCP
A tiny bridge that exposes any Pumperly instance as an MCP server, enabling LLMs to query real-time fuel prices, find stations, plan routes, and geocode locations.
---
## What you get
| Type | What for | MCP URI / Tool id |
|---------------|----------------------------------------------------------------|----------------------------------|
| **Resources** | Browse configuration, statistics, and exchange rates read-only | `pumperly://config`
`pumperly://stats`
`pumperly://exchange-rates` |
| **Tools** | Find stations, calculate routes, and geocode locations | `find_nearest_stations`
`get_stations_in_area`
`calculate_route`
`find_route_stations`
`geocode` |
Everything is exposed over a single JSON-RPC endpoint (`/mcp`).
LLMs / Agents can: `initialize` -> `readResource` -> `listTools` -> `callTool` ... and so on.
---
## Quick-start (Docker Compose)
```yaml
services:
pumperly-mcp:
image: drumsergio/pumperly-mcp:latest
ports:
- "127.0.0.1:8080:8080"
environment:
- PUMPERLY_URL=https://pumperly.com
```
> **Security note:** The HTTP transport listens on `127.0.0.1:8080` by default. If you need to expose it on a network, place it behind a reverse proxy with authentication.
## Install via npm (stdio transport)
```sh
npx pumperly-mcp
```
Or install globally:
```sh
npm install -g pumperly-mcp
pumperly-mcp
```
This downloads the pre-built Go binary from GitHub Releases for your platform and runs it with stdio transport. Requires at least one [published release](https://github.com/GeiserX/pumperly-mcp/releases).
## Local build
```sh
git clone https://github.com/GeiserX/pumperly-mcp
cd pumperly-mcp
# (optional) create .env from the sample
cp .env.example .env && $EDITOR .env
go run ./cmd/server
```
## Configuration
| Variable | Default | Description |
|----------------|--------------------------|--------------------------------------------------|
| `PUMPERLY_URL` | `https://pumperly.com` | Pumperly instance URL (without trailing /) |
| `LISTEN_ADDR` | `127.0.0.1:8080` | HTTP listen address (Docker sets `0.0.0.0:8080`) |
| `TRANSPORT` | _(empty = HTTP)_ | Set to `stdio` for stdio transport |
Put them in a `.env` file (from `.env.example`) or set them in the environment.
## Testing
Tested with [Inspector](https://modelcontextprotocol.io/docs/tools/inspector) and it is currently fully working. Before making a PR, make sure this MCP server behaves well via this medium.
