Implementation Reference

• adapters/mcp/server-stdio.js:433-441 (handler)

  The handler logic for describe_semantic_entity (which is the actual implementation for the describe_reliability_entity tool). It retrieves the entity definition from the SemanticSchema via describeSemanticSchema().

  case 'describe_semantic_entity': {
    const { describeSemanticSchema } = require('../../scripts/semantic-layer');
    const schema = describeSemanticSchema();
    const entity = schema.entities[args.type] || schema.metrics[args.type];
    if (!entity) {
      throw new Error(`Unknown semantic entity: ${args.type}`);
    }
    return toTextResult(entity);
  }

• scripts/tool-registry.js:186-194 (registration)

  Registration of the describe_reliability_entity tool in the tool registry.

    name: 'describe_reliability_entity',
    description: 'Get the definition and state of a business entity (Customer, Revenue, Funnel). Aliased to describe_semantic_entity.',
    inputSchema: {
      type: 'object',
      properties: {
        type: { type: 'string', enum: ['Customer', 'Revenue', 'Funnel'] },
      },
    },
  }),

• scripts/semantic-layer.js:86-88 (helper)

  The helper function that provides the semantic schema definition used by the tool handler.

  function describeSemanticSchema() {
    return SemanticSchema;
  }
