Implementation Reference
- src/index.ts:304-366 (handler)The handler function for the get_hook_example MCP tool. Retrieves a React Native hook example by name from the codebase examples directory, supporting exact and fuzzy matching, and returns markdown content or error messages.async ({ hook_name }) => { if (!hook_name) { return { content: [ { type: "text", text: "Hook name not specified", }, ], }; } try { // First try exact match const result = getExampleContent("hooks", hook_name); if (result.error) { // Try to find by fuzzy match const hooksDir = path.join(CODE_EXAMPLES_DIR, "react-native", "hooks"); const closestMatch = findClosestMatch(hooksDir, hook_name); if (closestMatch) { const fuzzyResult = getExampleContent("hooks", closestMatch); return { content: [ { type: "text", text: fuzzyResult.content?.[0] ?? fuzzyResult.error ?? "Error: No content available", }, ], }; } else { return { content: [ { type: "text", text: `Hook ${hook_name} not found`, }, ], }; } } return { content: [ { type: "text", text: result.content?.[0] ?? result.error ?? "Error: No content available", }, ], }; } catch (err) { console.error(`Error getting hook example ${hook_name}:`, err); return { content: [ { type: "text", text: `Error getting hook example: ${err}`, }, ], }; } },
- src/index.ts:301-303 (schema)Zod input schema for the get_hook_example tool, defining the required hook_name string parameter.{ hook_name: z.string().describe("Hook Name"), },
- src/index.ts:298-367 (registration)Registration of the get_hook_example tool on the MCP server using server.tool() with name, description, schema, and inline handler.server.tool( "get_hook_example", "Get a React Native hook example", { hook_name: z.string().describe("Hook Name"), }, async ({ hook_name }) => { if (!hook_name) { return { content: [ { type: "text", text: "Hook name not specified", }, ], }; } try { // First try exact match const result = getExampleContent("hooks", hook_name); if (result.error) { // Try to find by fuzzy match const hooksDir = path.join(CODE_EXAMPLES_DIR, "react-native", "hooks"); const closestMatch = findClosestMatch(hooksDir, hook_name); if (closestMatch) { const fuzzyResult = getExampleContent("hooks", closestMatch); return { content: [ { type: "text", text: fuzzyResult.content?.[0] ?? fuzzyResult.error ?? "Error: No content available", }, ], }; } else { return { content: [ { type: "text", text: `Hook ${hook_name} not found`, }, ], }; } } return { content: [ { type: "text", text: result.content?.[0] ?? result.error ?? "Error: No content available", }, ], }; } catch (err) { console.error(`Error getting hook example ${hook_name}:`, err); return { content: [ { type: "text", text: `Error getting hook example: ${err}`, }, ], }; } }, );
- src/index.ts:64-84 (helper)Helper function called by the handler to locate and read the content of example files in the react-native/{subcategory} directories.// Helper function to get example content function getExampleContent(subcategory: string, filename: string): { content?: string[]; path?: string; error?: string } { const searchDir = path.join(CODE_EXAMPLES_DIR, "react-native", subcategory); const filePath = findFileInSubdirectories(searchDir, filename); if (!filePath || !fs.existsSync(filePath)) { return { error: `Example ${filename} not found` }; } try { const content = fs.readFileSync(filePath, 'utf8'); return { content: [content], path: path.relative(BASE_DIR, filePath) }; } catch (err) { console.error(`Error reading example ${filename}:`, err); return { error: `Error reading example ${filename}` }; } }
- src/index.ts:87-109 (helper)Helper function used for fuzzy matching of hook filenames when exact match fails.function findClosestMatch(directory: string, searchName: string, extensions: string[] = ['.js', '.jsx', '.ts', '.tsx']) { if (!fs.existsSync(directory)) return null; let closestMatch = null; for (const ext of extensions) { const files = glob.sync(`${directory}/**/*${ext}`); for (const filePath of files) { const fileName = path.basename(filePath); const fileNameNoExt = path.basename(fileName, path.extname(fileName)); if (fileNameNoExt.toLowerCase().includes(searchName.toLowerCase())) { closestMatch = fileNameNoExt; break; } } if (closestMatch) break; } return closestMatch; }
