Create, track, retrieve, update, and delete custom business metrics for configs. Covers full lifecycle: define metrics with the LaunchDarkly MCP server, emit events via SDK, and query results.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Custom Metrics for Configs
Full lifecycle management of custom business metrics: create metric definitions with the MCP server, track events via SDK, retrieve metric data, and manage metrics programmatically.
## Prerequisites
- LaunchDarkly AI SDK initialized (see `sdk-install`). The SDK reads `LD_SDK_KEY` from the environment.
- The remotely hosted LaunchDarkly MCP server configured in your environment
- A LaunchDarkly API token with the `writer` role, only to update or delete metrics, or for scripts that can't use MCP
- Understanding of built-in agent metrics (see `built-in-metrics`)
## API Access
Use the LaunchDarkly MCP server tools wherever one exists: they authenticate via OAuth and need no token. Create metrics with `create-metric`, check that events are arriving with `list-metric-events`, and read definitions with `get-metric` and `list-metrics`. The MCP server can't update or delete metrics, so those steps use the REST API. For them, or for scripts that can't use MCP, ask the user to paste an API access token for this session and substitute it for `{api_token}` in the examples below. Do not search environment variables, `.env` files, or agent/MCP config files for…

How to install
mdr add launchdarkly/ai-tooling/custom-metrics@sha256:9645e1adf79b8685The line at the top of this page pins the label v1.1.0-experimental, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
