Open Quality
Open healthcare quality measures: CQL, SQL and FHIR with provenance and known issues
Should I use this
Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢search_measures(query, collection, dataModel, kind, limit)
Find measure packages by CMS id, title words, steward or package id. Every word must match. Shared CQL libraries are packages too; pass kind "library" to search them.
Input Schema
{
"type": "object",
"properties": {
"query": {
"type": "string",
"minLength": 1,
"maxLength": 200,
"description": "Words to match, for example \"CMS122\" or \"diabetes glycemic\""
