registerToolHandler("get_spend_limit", async (request: ToolCallRequest) => { try { const params = validateParams(request.params.arguments); const client = getBrexClient(); const spendLimit = await client.getSpendLimit(params.id); return { content: [{ type: "text", text: JSON.stringify({ spend_limit: spendLimit }, null, 2) }] }; } catch (error) { logError(`Error in get_spend_limit: ${error instanceof Error ? error.message : String(error)}`); throw error; } }); - src/tools/index.ts:123-133 (schema)MCP tool schema definition for 'get_spend_limit', specifying input as object with required 'id' string field.
