Implementation Reference
- src/core/mcp-shared.js:219-225 (handler)Primary handler for get_onyx_structs tool: delegates to SearchEngine for examples and formats MCP response with context.
async getOnyxStructs(structName, limit = 10) { const results = await this.searchEngine.getOnyxStructExamples(structName, limit); const toolMessage = structName ? `Searching for Onyx struct definitions: "${structName}"` : 'Searching for all available Onyx struct definitions'; return this.formatResponse(JSON.stringify(results, null, 2), toolMessage); } - src/core/search-engine.js:164-189 (helper)Core helper logic: loads githubPatterns data, filters Onyx struct definitions by optional structName, limits results, and formats output.
async getOnyxStructExamples(structName = null, limit = 10) { const patterns = await this.loadData('githubPatterns'); if (!patterns) { return { error: 'GitHub patterns not available. Run GitHub crawler first.' }; } let structs = patterns.structs || []; if (structName) { // Filter by struct name (partial match) structs = structs.filter(struct => struct.definition.toLowerCase().includes(structName.toLowerCase()) ); } return { query: structName, totalFound: structs.length, examples: structs.slice(0, limit).map(struct => ({ definition: struct.definition, file: struct.file, repository: struct.repository, url: struct.url })) }; } - src/core/mcp-shared.js:78-88 (schema)Tool definition with name, description, and input schema (structName: optional string, limit: optional number default 10). Used for MCP tool listing.

setupHandlers() { // List all available tools this.server.setRequestHandler(ListToolsRequestSchema, async () => { return { tools: TOOL_DEFINITIONS }; }); // Handle tool calls this.server.setRequestHandler(CallToolRequestSchema, async (request) => { const { name, arguments: args } = request.params; return await this.mcpImpl.executeTool(name, args); }); } - src/core/mcp-shared.js:634-635 (registration)Specific dispatcher case in executeTool method that invokes the getOnyxStructs handler for this tool.
