Meter — plugin for Claude Code and Codex

Meter is the taxi meter and fleet platform: drivers run a meter in the Meter app, fleets manage drivers, vehicles, fares, scheduled bookings and money, and riders book rides from fleets. This plugin gives your agent the view you already have in the Meter apps, through the hosted MCP server, with your own Meter sign-in. One repository, native packaging for each client, plus the vendor-neutral Open Plugins manifest.

Sign in with your Meter account. The first time a tool is used, your agent opens a Meter sign-in in the browser (OAuth 2.1 with PKCE). The connection it gets is exactly as powerful as you are: owners and admins see fleet-wide data, drivers and riders see their own.

Install

Claude Code

/plugin marketplace add MeterApp/meter-plugins
/plugin install meter@meterapp-meter

Codex

codex plugin marketplace add MeterApp/meter-plugins
codex plugin add meter@meterapp-meter

Skills only, any agent

npx skills add MeterApp/meter-plugins

Server only, no skills

claude mcp add --transport http meter-fleet https://www.meterapp.co/api/mcp/fleet
claude mcp add --transport http meter-rides https://www.meterapp.co/api/mcp/rider

Start a new session, then try:

"How much did my fleet earn last week, and which driver had the most trips?"

"Book me a ride to the airport at 6am with my usual taxi company."

Claude and ChatGPT (no terminal)

Add a custom connector with the URL https://www.meterapp.co/api/mcp/fleet (driving or running a fleet) or https://www.meterapp.co/api/mcp/rider (booking rides) in the app's connector settings and sign in to Meter when asked. The skills are optional there: the server explains its own tools and asks for a preview and your yes before anything changes.

Keep it up to date

• Claude Code updates the plugin by itself at startup once auto-update is on for its marketplace, which Claude Code leaves off for marketplaces outside Anthropic's: open /plugin, go to Marketplaces, choose meterapp-meter and select Enable auto-update. By hand: /plugin marketplace update meterapp-meter, then /plugin update meter@meterapp-meter, then restart (or /reload-plugins).
• Codex: codex plugin marketplace upgrade meterapp-meter.
• Skills only: npx skills update.

Added this marketplace before 1.4.0, when it was called meterapp? CHANGELOG.md shows how to move your install to the new name.

The CLI, @meterapp/meter, installs its own new versions in the background, and meter update updates it now and refreshes this plugin wherever Claude Code or Codex has it installed.

What you get

Six skills and the hosted MCP server.

Skill	Job
meter-ride	Booking, following and cancelling your own taxi ride: confirmed addresses, the price first, your yes before booking
meter-fleet-insights	Questions about a fleet's trips, bookings, drivers, vehicles, earnings and accounting
meter-fleet-onboarding	Walking a new fleet owner through setup with the onboarding checklist and settings tools
meter-settings-changes	Changing fleet, booking, ride-option or personal settings: dry run, confirm, apply
meter-driver-personal	An individual driver's own trips, earnings, pay stubs, availability and profile, and a rider's past rides
meter-api-explainer	"How does this work / what does this field mean", and drafting integrations

The MCP servers at https://www.meterapp.co/api/mcp/fleet (Meter for Drivers & Fleets) and https://www.meterapp.co/api/mcp/rider (Meter Rides) provide the tools listed in references/tools.md; the objects they return are in references/data-model.md. Both files are generated from the server's own catalog. The server also describes itself: describe_api returns a domain index by default; pass domain to browse its tools or tool for full detail. explain_data explains any result field.

Sign-in

Surface	How you sign in
Hosted MCP	Your host opens the Meter sign-in (OAuth 2.1) and keeps the connection
Meter CLI (separate package)	npx @meterapp/meter login, the same Meter sign-in; meter call <tool> --dry-run previews any write

The host discovers the sign-in from each server's 401 challenge and its metadata at https://www.meterapp.co/.well-known/oauth-protected-resource/api/mcp/fleet or …/api/mcp/rider. The plugin itself asks you for nothing: you only ever sign in on meterapp.co. Details in references/authorization.md.

Safety model

• Read first, ask second. whoami tells the agent who is signed in and which fleets and roles they have; ids come from results, never from guesses.
• Every settings change is a dry run first. dry_run defaults to false, so the agent passes dry_run: true, shows the exact changes (field, from, to), waits for an explicit yes, then repeats the call to apply. Fares are never changed without stating the from and to values.
• A permission error is final for that person. The agent switches to a tool that fits their role instead of retrying.
• Results never contain payment-provider ids, GPS traces, internal notes or other people's contact details beyond what the role allows. See references/safety.md.
• Rides are booked only for the signed-in rider, only after a preview of the price, pickup time, payment and cancellation policy, and only on an explicit yes. Nothing is paid in the chat: when a ride needs paying for, the agent gives you a Meter checkout link (valid about 30 minutes, only for you) and the ride is booked once you have paid on meterapp.co; it then checks the booking before saying so. Rides the company takes payment for after the trip, and free rides, are booked in the chat. The agent never asks for or types card details. Cancelling shows the fee first.

What the plugin sends, and where

Everything goes to Meter's hosted MCP servers, https://www.meterapp.co/api/mcp/fleet and https://www.meterapp.co/api/mcp/rider, authenticated by your host with your own Meter sign-in. The agent sends the arguments of the tools it calls, which can include addresses you ask it to search or book, ride times and booking ids. The plugin is instructions and two server addresses: it runs no code on your machine and sends nothing anywhere else. How Meter handles that data: privacy policy. To disconnect, remove the connector in your host or revoke it in Meter under Account, Connected apps.
