§ OVERVIEW
Look up and search packages on npm, PyPI, and crates.io — latest version, license, dependencies, repository. The "what version is X / is this package maintained" tool agents reach for constantly.
- › What is the latest version of the npm package "zod" and its license?
- › Search PyPI for HTTP client libraries
- › Get crates.io info for "serde"
mcpmeter sits between agent and publisher: authenticate the bearer key, forward the JSON-RPC body unchanged, count tool-call envelopes in the response, write a ledger row, return the response unchanged. The publisher never sees the consumer's API key. The consumer never sees the publisher's secret. The proxy is open source so the meter can be inspected.
§ TOOLS
2 tools Read tools are read-only; write tools mutate state. Tap any read tool to try it inline.

§ INTEGRATION
Pick your client. The proxy URL and bearer key go into your client's MCP config. The same shape works in 30+ MCP-compatible agents — for clients not listed, see the docs ↗.
Cursor & VS Code prompt for permission then install. Claude Code: paste the copied command into your terminal.
Paste, save, restart your client. It'll prompt you to "Authenticate" — click it, sign in here, done. No keys to manage.
Paste your mcpm_live_… key into the snippet. Older clients without OAuth support, scripts, and curl all use this.

The proxy authenticates the bearer token, looks up the price, forwards the call to the upstream MCP, returns the response unchanged, and writes a usage record.
§ PRICING
PER_CALL pricing at $0.0002 / call (USD).
Each consumer gets 30 calls / month at no cost. Resets on the 1st. After the allowance, calls bill at the per-call rate above.
§ TRUST & COMPLIANCE
JSON-RPC bodies pass through. We log call metadata only.
For PCI scope, mcpmeter is a network passthrough.
Metering code is auditable on GitHub ↗; reconciles to Stripe nightly.
13 months retention in your region. CSV export.
