Implementation Reference
- src/tools/init-chain.ts:5-13 (handler)The handler implementation for the aga_init_chain tool.
export async function handleInitChain(args: { specification_hash?: string }, ctx: ServerContext) { if (ctx.chainInitialized) return ctx.error('Chain already initialized'); const genesis = createGenesisEvent(ctx.chainKP, args.specification_hash ?? sha256Str('AGA Protocol Specification v2.0.0')); await ctx.storage.storeEvent(genesis); ctx.chainInitialized = true; ctx.portal.sequenceCounter = 0; ctx.portal.lastLeafHash = genesis.leaf_hash; return ctx.json({ success: true, genesis_event_id: genesis.event_id, genesis_leaf_hash: genesis.leaf_hash }); } - src/server.ts:80-92 (registration)Tool registration of aga_init_chain in the MCP server.
