Implementation Reference
- src/mcp.ts:245-255 (registration)Registration of the MCP 'create-handler' tool, including description, input schema using Zod, and handler function that invokes the addHandler helper to create the handler in the AO process.this.server.tool( "create-handler", "create a new handler in an existing AO process", { processId: z.string(), handlerCode: z.string() }, async ({ processId, handlerCode }) => { const result = await addHandler(processId, handlerCode, this.signer); return { content: [{ type: "text", text: cleanOutput(result) }], }; } );
- src/helpers/handlers.ts:31-53 (helper)Helper function that implements the core logic for creating a handler by sending the handlerCode as data in an 'Eval' action message to the specified AO process and returning the result.export async function addHandler( processId: string, handlerCode: string, signer: any ) { const messageId = await message({ process: processId, signer, data: handlerCode, tags: [{ name: "Action", value: "Eval" }], }); await sleep(100); const outputResult = await result({ message: messageId, process: processId, }); return outputResult.Output ? outputResult.Output.data : outputResult.Messages[0].Data; }
