Implementation Reference
- src/handlers/helius.ts:64-71 (handler)Handler function that executes the getBlockHeight logic by calling Helius SDK's connection.getBlockHeight and returning a success or error response.
export const getBlockHeightHandler = async (input: GetBlockHeightInput): Promise<ToolResultSchema> => { try { const blockHeight = await (helius as any as Helius).connection.getBlockHeight(input.commitment); return createSuccessResponse(`Block height: ${blockHeight}`); } catch (error) { return createErrorResponse(`Error getting block height: ${error instanceof Error ? error.message : String(error)}`); } } - src/handlers/helius.types.ts:12-14 (schema)Input type definition for GetBlockHeight, accepting an optional commitment parameter.
export type GetBlockHeightInput = { commitment?: "confirmed" | "finalized" | "processed"; } - src/tools.ts:45-55 (registration)Registration of the 'helius_get_block_height' tool in the tools array with its name, description, and input schema.
