Implementation Reference
- src/tools/get-project-feature.ts:19-67 (handler)Handler function that executes the getProjectFeature tool logic: calls the Unleash helper, handles errors, and formats the response as MCP content.
export async function handleGetProjectFeature({ projectId, featureName }: { projectId: string, featureName: string }) { try { // Get the feature flag from the project const feature = await getProjectFeature(projectId, featureName); if (!feature) { return { content: [{ type: "text", text: JSON.stringify({ success: false, projectId, featureName, error: `Feature '${featureName}' not found in project '${projectId}'` }, null, 2) }], isError: true }; } const statusInfo = feature.enabled !== undefined ? `The ${featureName} flag is currently ${feature.enabled ? 'enabled' : 'disabled'}.` : ''; return { content: [{ type: "text", text: JSON.stringify({ success: true, feature, summary: `Feature '${featureName}' in project '${projectId}' retrieved successfully. ${statusInfo}` }, null, 2) }] }; } catch (error: any) { return { content: [{ type: "text", text: JSON.stringify({ success: false, projectId, featureName, error: error.message || 'An unknown error occurred' }, null, 2) }], isError: true }; } } - Zod schema defining the input parameters for the getProjectFeature tool: projectId and featureName.
export const GetProjectFeatureParamsSchema = { projectId: z.string().describe('ID of the project'), featureName: z.string().describe('Name of the feature flag') }; - src/server.ts:151-155 (registration)Registration of the getProjectFeature tool on the MCP server using server.tool().
getProjectFeatureTool.name, getProjectFeatureTool.description, getProjectFeatureTool.paramsSchema as any, getProjectFeatureTool.handler as any ); - Supporting function that performs the actual API request to retrieve a specific feature flag from Unleash.
export async function getProjectFeature(projectId: string, featureName: string): Promise<any | null> { try { const response = await client.get(`/api/admin/projects/${projectId}/features/${featureName}`); logger.info(`Successfully fetched feature ${featureName} from project ${projectId}`); return response.data; } catch (error: any) { logger.error(`Error fetching feature ${featureName} from project ${projectId}:`, error); if (error.response && error.response.status === 404) { logger.info(`Feature ${featureName} not found in project ${projectId}`); return null; } throw error; } }
