Implementation Reference
- src/tools/tool-call.ts:26-66 (handler)The `execute` method implements the core logic of the 'tool_call' tool. It constructs a URL with the specified tool and method, sends a POST request with parameters using veyraxClient, and returns the response as formatted JSON. Includes error handling for 404 (not found) and 500 (server error) cases.
async execute({ tool, method, parameters, question }: z.infer<typeof this.schema>) { try { const url = `/tool-call/${tool}/${method}?include_component=false${question ? `&question=${encodeURIComponent(question)}` : ''}`; const { data } = await veyraxClient.post(url, parameters); return { content: [ { type: "text" as const, text: JSON.stringify(data, null, 2), }, ], }; } catch (error: any) { console.error(`Error calling tool ${tool}.${method}:`, error); if (error?.response) { if (error.response.status === 404) { return { content: [ { type: "text" as const, text: `Tool or method not found: ${tool}.${method}. Please check the tool name and method name.`, }, ], }; } else if (error.response.status === 500) { return { content: [ { type: "text" as const, text: `Server error occurred while calling ${tool}.${method}. Please try again later.`, }, ], }; } } throw error; } } - src/tools/tool-call.ts:15-24 (schema)Zod schema defining the input structure for the 'tool_call' tool, including required fields: tool (string), method (string), parameters (object), and optional question (string).
